I dont have a reccomendation for speakers, but pay attention to the RMS and not so much the peak power of your reciever. Peak power can only last a short time, as in a musical burst of energy. I find the better your reciever up front, the better your speakers sound (unless you've got seperate amplification) Also, I've read you're not supposed to mix different speakers for front and back because often they will give out a different sound. However, I mixed some Pioneer TS 6-1/2's in the front and Kenwood KFC 6x9's in the back. They sound pretty damn good. Im sure if you go with a decent brand name speaker you won't be unhappy with them. ANYTHING is better then those factory speakers..unless you own like a BMW or something.
I find this website to be usefull with what fits your car and what harness's are needed ect.. http://www.crutchfield.com/

i plan on getting the same brand all around, and im also undecided whether i should get another amp to run them or just run them straight off the headunit.
i dont really care for loudness (as most ppl do when they bump down the street) i just want my system to sound good. the stock speakers are fucking killing my desire for music.
ugh.

Infinitys are excellent speakers and don't require a honkin' huge amp to sound great. The Kappa series will sound smoother (especially on strings, piano, and vocals) than the Reference series. The Kappa series also gives you better efficiency than the Reference series, so you get the most out of the power you do have available to you.
This does NOT mean either series is necessarily more efficient than the speakers you currently have -- it may very well be that they are LESS efficient, in which case you'll have to turn up the volume a tad to attain the same sound levels you're currently getting. But the increase in quality of the sound is worth the loss of a bit of max volume, especially if you're not a bumper.

I sold high end car audio from 1981 to 1983, and I've kept up with developments just because I've always been interested in fine audio gear. Infinity's car speakers have always been top notch. Not the cheapest speakers by any stretch of the imagination, but very tough to beat at any price when it comes to speakers which will fit into existing installations rather than going with custom enclosures (although they have speakers for those applications, too).

so guys, i can get the KAPPA462.7CFP 4" x 6" & KAPPA693.7I 6" x 9"
on ebay for around $200
can i get by (for now) w/o an amp to push them without them distorting or being ruined? i already have an amp & subwoofer, so if i was to get an amp for just those 4 speakers, what type of amp should i get? like how many channels? how many watts? etc etc.
i just got my tax refund and i want at least *something* to show for it before its sucked away to bills. =[

Your car deck puts out MAYBE 15rms per channel. Dont believe those listed wattage numbers.
You can try infinity, but they tend to be powerhogs for the kappas.

yes, they work just fine without an amp, when you get one turn the gain down on all the amps to about 3/4 as opposed to full, it'll prevent the distortion you'd get normaly at higher volumes

without going overboard, a 100 to 200 watt 4 channel is sufficient to have decent sound without rattling the the fenders off the car, also look into picking up a digiat signal processor

^Exactly. Those number are usually garbage. Plus the speakers will sound much better with a descent amp powering them rather than the deck. Go look at sounddomain.com. They're a bunch of car audio nuts. They have a tendency to bicker though. Also, I suggest you just use the front speakers because using the rears will only distort and drag your sound stage back from your ears. I would also suggest component speakers as opposed to coaxials or triaxils or the most ridiculous quadaxials. there are a ton of different speakers out there. take a look at CDT, or resonant engineering. I'm curious to see RE perform because i've heard nothing but good things about their subwoofers. Infinity's are good for the money as well. For the amp, if you have the money, zapco is really good. other wise an old rockford fosgate would do the job well. good luck

MB Quart.... you want badass sound, look 'em up. I put 2 2" tweets, 4 3-way 6x9's, and then added a Precision Power 2 channel 400w amp for my 2 Power Accoustic 10" in a tuned and sealed box. It's NOT cheap but DAMN! they are nice.... I don't think they're breakable! You can really REALLY push the limit of power with them and they have never crackled, popped, or made any kind of distortion that I can discern.... but I'm deaf 'cause of my car stereo...

I'm a Kenwood Excelon fan, you should check out some of their stuff, their midrange holds high RMS, and their amps can power it too, plus they've got a good frequency range.

I second the MB quart suggestion, but i really hate 3 ways. they always sound terrible. i wouldn't do anything more than a coaxil. Polk has some descent stuff too

I love the W7 too, but it's way too overpriced. You can get a resonant engineering XXX for less than half the price and it sounds almost as good. or a brahma for the same price but sounds even a little better than the xxx. Alpine head units are pretty good, but i'm not all that happy with their speakers

Head units are a bit more preference and application dependant. I have used alpine and Blaupunkt (sp?).... wasn't much difference between the 2 but the price... Actually, Sony makes some excellent head units too, even if they aren't "cool" technophile units. I like the double din units best though, if you have the dash space. Better display, usually you can get doubles with higher power ratings, and they flip open all stylish like...

MB Quart is a pile of suck now 
CDT is a much better route for decent quality coaxials without to much cost. So is infinity, though I find their tweeters a bit harsh.
Image dynamics makes some nice stuff as well, not sure if they even have coaxials though.
Buy a small amp that puts out 100rms over 2 channel (or 100rms over 4 channels if you want to add a single sub later) and buy a decent set of components for 200ish or so. JL Audio XR's are nice, DLS, CDT, etc.

If you can find the CDT CL61A for cheap like this, I would definitly go with this, along with a ~150 watt rms x 2 at 4 ohms amplifier. I would ditch the rear speakers and use the extra money if you can't afford two sets of speakers and an amp. Believe me, one set of good comps like these powered by a good amp will be plenty loud and sound mightly clean to boot. Rock on.

Yup. Rear stage just screws up the image anyways. A properly ampd front stage will fill an entire car loud enough to go past your ears distortion points anyways.
40, you've heard my last car. You only need a decent set of front components and a nice 100 watts a channel to make em sound good. A single 12 with decent power will fill a low end.

If you don't mind gettin' your hands dirty, cuttin' up your car a bit and runnin' multiple wires -- talk to Dylan Matlow over at OlogyAudio. I've used one of his crossover sets with a dayton reference series midwoofer and tweeter and its great. He's also got more customized solid equipment on the way (workin' with a partner to start their own speaker build house), but who knows how long that'll take to come to fruition.
CDT's a solid brand, but they're mainstream -- run with the little guy and create some change!

you could always get a 4 channel amp and run your speaker through that. Good speakers need CLEAN power that's consistent. RMS is key and using good cables is also key. I had a 4 channel JBL amp going to polk audio and the sound was GREAT!. IF you have a small car battery a capacitor cap is good to take strain of the battery.

Forget the rear fill. Stick with fronts, and a small sub. Also, let me echo the infinity suggestions. 
If you're able to and willing to do things right, and mount for much better sound, get these: http://search.ebay.com/5863024688 (166$ shipped)
Since you're not too concerned with bass, a cheap 10" sub will do the trick: http://search.ebay.com/5864377416 (~50$ shipped)
To power everything, this is a great amp, and gives you the options to expand and change your system as you see fit in the future. Its a great amp. http://search.ebay.ca/5761a (260$ shipped)
To hook everything up, just get any old 4gauge amp kit: http://search.ebay.com/5865081034 (30$ shipped)
50' 12gauge Speaker wire: http://search.ebay.com/5862709354 (17$ shipped)
20ft Twisted pair RCA connects: http://search.ebay.com/5861901254 (20$ shipped)
3/4" MDF 10" sub enclosure, proper dimenions to match sub. Get it locally.. should be about 25$.
So everything you need for a total of about 575$ shipped.
Those 4x6" speaker mounts are probably not in the most ideal position, and probably won't give very good imaging, regardless of the speaker's quality. You're most likely much better off cutting the doors and mounting the speakers there, or molding them in the kicker panels.. For the parts I suggested, I'd strongly suggest running that amp in trimode, which would give you 2 channels at 150wrms, and a single 280wrms channel for the woofer. I'd go for those components, running off the two 150w channels, and forget rear fill. Place the component's subs in the kicker panels, and the tweeters in the window columns (google on how to do this correctly). Mount the amp to the back of your trunk, and put the sub in an MDF enclosure in the trunk facing towards the front of the car. The amp will provide plenty of clean power for your speakers, and you'll never have to worry about it sending nasty clipped power. Adjust and tune everything to your liking... and you'll have one kick ass system. If you want to bring the SQ up a notch, replace the cheap sub with a decent 10".. like an infinity kappa perfect, which you can find typically on ebay for around 130$ shipped.
Best of luck on your system.. its an addicting hobby... and I only wish I had done it right the first time, rather than wasting time with cheaper components, and poor mounting locations.
Buy nice, or buy twice, they always say.. and do it right, do it once... etc. etc.

Also, forget stiffening caps. I don't feel like getting into it, but they don't do anything. If you're having power troubles, get a better altenator, and a better battery.
Screw caps. :P

the thing I hate about most car systems is not only the shitty rattling sound caused by everything vibrating, its the size of speakers they have in there.
18 inch speakers? wtf? they reproduce down to atleast 40 Hz... and the wavelength on most of the subsonic frequencies is 10 to 30 feet long. you cant even hear anything under 80 Hz sitting in a car.

Nuh UH!! Sorry to disagree, but this statement is almost completely false. I do agree that using any sub larger than a 12" in a car is rediculous, but, properly configured bass drivers can produce strong 20-100hz sub bass frequencies which you can not only hear, but FEEL all the way from your hair to the tips of your toes. With the bass set up right in a car system, you should not be able to tell what kind of car is following you too closely without holding the rear view mirror with your hand. Play Alanis Morrisette's "You Learn" on a system with great subs and the ending (26hz) loooonnnng bass note will rattle your intestines and yes, you can HEAR it too.

With small systems, I agree, however, if you're running a 600 Watt HiFonics Zeus amp (or the like) driving (4) 10" or 12" subs, you better have at least one huge stiffening capacitor unless you like seeing your headlights dim with the bass beat as you drive at night.

(im drunk right now)
ya'll spoke too late, but im satisfied with my purchase. since i got them online its going to take a few days to get to me, but i went to frys electronics today and got to listen to both sets simaltaneously & im very fuckin impressed.
i took the recommendations of everyone & got these
for teh front: KAPPA462.7CFP 4" x 6" & for teh rear: KAPPA693.7I 6" x 9"
and to boot i picked up this amp to run them: Rockford Fosgate ? - P4004
was thinking to run them at 100 W x 4 @ 2 Ohms RMS.
i already have a 12" sub & amp (forgot the brand names, i think JL or polk or some shit.)
so im going to run both amps. what does worry me tho, is just the amp alone that i have right now, when the bass hits hard/loud enough, it turns my headunit off. if i run 2 amps, im pretty sure its going to happen all the time if i dont do something about it. will a 1 farad capacitor prevent this? (i just read from someone up there that they are garbage??)
i JUST bought & installed a brand new alternator last month, the best one they had + lifetime warranty.
annyway, comments, questions, suggestions, etc.
p.s
freezy your ride is dope you big show off. 
=P
honestly, if i have anyone to blame its you. you FUCKED my musical appreciation up. everything was fine until i stepped into your ride & heard your system. now everything else sounds like CRAP to me. thanks buddeh. 
p.p.s i love this thread. all the cool ppl come out to talk shop.

Well, you can't do that unless you buy 4 pairs of speakers and then you'll still end up with 50 watts per speaker. You see, the speakers have a 4 ohm impedence, so you're only gonna get 50 watts x 4 from that amp. You'll also have a rear stage with the fader set at midlle position, a big mistake according to everyone in this thread, including me. I'd have taken most people's advice and custom installed a large pair of seperates in the doors or kick panels and just eliminated rear fill altogether.
Quote:

Something's not wired right. You should have the amp grounded to the body as close to the amp as possible and the main power feed should be at least 4 guage run right to the battery positive terminal. Your head unit should also be properly grounded (both by the back strap and the ground wire) and fed 12V+ by the car's factory power lead. Since you're adding a second amp, you should get a 2 guage positive lead to run from the battery to a 50 amp circuit breaker (within 2 feet from the battery) then to the trunk where you'll connect it to a fuse block that will distribute the power to your two amps.
It is also advisable to run at least a 6 guage ground wire from the battery to the same bolt you use to ground your amps. That provides a solid ground for the amps and prevents ground loops.

"Sounding nice" means having a FRONT stage. When you go to a concert do you face the back wall so that the majority of sound comes from behind you?
40, you're a very cool dude and I don't mean any disrespect, but I not only used to be an auto accessory installer for 5 years, but I had a $12,000 stereo system in my '95 GTP. I made a lot of mistakes in the design and ended up installing the system 4 times with redesigns each time before I finally got it right. That $12,000 system cost me over $22,000 because I was lazy and paid two different shops to do the labor. Also, there was a lot of custom fabrication that I didn't have the tools or facilities to do myself.
The point is, it was a learning experience galore. Admittedly, I'm a serious car audiofile and you're not, but you're the one who asked for advice and didn't take the best advice you got. Now you'll have the same learning experience on a smaller scale.
You'll probably live with the system, as it will sound WAY better than what you have now, but you'll wish you did the larger speakers up front and you will next time.

i said up there^ 'im drunk' (disclaimer!) so i may come off like a drunktard. 
you confused me talkin about "4 pairs" of speakers, i was like huh?  i was only looking for more/definate clarification from you in my last post. (not the cocky rebuttal as you assumed.)
if this front sound stage shit is really all that important to me sometime in the future, all i would need is a bigger pair in the front & disconnect the rears. no biggy im not sweatin it. 
in your opinion, i didnt take 'the best advice'. in my opinion, i chose what i chose for what i felt best suites MY needs & im beyond satisfied with what i chose.
anyway, no hard feelings TM. yer a chill dude  btw, ill be looking for your advice on a motorcycle that was givin to me. more details on that later.

Basic psychoacoustic laws state that a soundwave has to make one full wavelength before it can even be heard, which means that if something has a 20 foot wavelength, you will have to be 20 feet away to hear it. Also, exposure to subsonic frequencies is horrible for your GI track.
Check out some psychoacoustic laws sometime....

You must be extremely confused.
Think about this: Hundres of thousands of dollars are spent each year on car audio systems.
The most elaborate systems can run upwards of 50-$60,000.00 or even more.
Most of these systems have an elaborate subwoofer system capable of response down to 20hz and even lower.
Why the hell would people pay for this if they can't HEAR it?
AND... Show me documentation that says that exposure to subsonic frequencies is "horrible for your GI track"...
I think you meant to say "tract" but you probably are as much aware of that as you are that there's really no such thing as "psychoacoustic laws".
Dude, get a clue.

I can hear down to about 30hz or so in my car with some noticable dB loss, but not a massive amount. Proper deadening and subwoofer aiming will bounce it back up front.
Phase also matters.

I almost wish I still had the GTP and I definitely wish I had pictures of it. Man, freezy, it'd blow your fuckin' mind. 1500 watts, 3 amps, 14 speakers, all active crossovers, 2 pairs a/d/s 325is, (4) 10" Kef free-air subs, 2 Focal 6.5" mid-bass drivers, Alpine 8939 with AI/net sound feild processor and AI/net changer. The amps: HiFonics Zeus (for the 4 subs) a/d/s 860-MX for the sats, HiFonics Olympus (only used half of it) for the Focals. RTA scored very high with a top db level of 127!! I even custom installed the guts of the Alpine remote into the steering wheel and used the factory buttons to control every feature! The head of the SFP with spectrum analyzer was mounted on the headliner in front of the moonroof on a perfect angle. I could go on and on, but you get the basic picture.
I'd take you up the offer of the a/b comparrison in a heartbeat. And blow you away.

Quote:
Infrasonic frequencies are felt as vibrations which, if intense enough, may result in feelings of nausea, vertigo and eventual black-out or internal hemorrhaging. Such sound or vibration is difficult to contain because of DIFFRACTION and RESONANCE effects, and the tendency for these vibrations to be transmitted through earth and building materials. The long-term physiological and psychological effects of constant exposure to these sounds are poorly understood. Quote:
Quote:
Low Frequency Noise To a degree, it is useful that we have a reduced sensitivity to the lower frequency range as it relieves us of being annoyed by low frequency sounds within and around us. However, very low frequencies, subsonic or infra-sounds, can be produced in buildings by long air-conditioning ducts and wind effects. Subsonic sounds generally act on the inner ear, the position-sensing organ, and significant levels may cause disorientation, seasickness, digestive disorders, troubled sight and dizziness.
Frequencies of between 1 and 8Hz can correspond to resonant frequencies within the body itself, 8Hz being thought to cause circulatory resonance phenomena, overloading the heart or bursting blood vessels. 7Hz also seems particularly unpleasant as it has been shown to cause tiredness, headache and nausea. It is suggested that 7 Hz corresponds to the median frequency of the brain's 'alpha' waves.
Quote:
Im willing to bet that if I rolled off 50Hz and below from your system you would not notice the difference while inside the car.

elemental audio systems stuff is dirt cheap as it isn't marketed, but is really quite good. If you want the best then go somewhere else. If you want pretty damn good for rock bottom prices so elemental.

Speaking of which, here is a pic of my Elemental Designs 15A in a ~4.5cuft ABC box. This is my old bassmobile .

Here it is again in a 1.5cuft sealed. Yes, a 15 in a small box is a good thing for a small trunk!

It was a rolling concert, man. Absolutely flawless (seemingly) AFTER the RTA/tune up.
But, yeah, I could have lived without the rear satellites, however, properly time-shifted, they were up front anyway.
