I know if I was to get into car audio, I'd go for a sealed sub.  Just personal preference.

4th order bandpasses are pretty intriguing.

nobody has mentioned this yet- but you'll definitely want good quality copper power and ground wires of a decent gauge to power your amp. finding a penetration in your car's firewall is way easier than drilling a new one. I assume your receiver has sub out connections? or are you trying to hook this up to a factory radio?

I used to have a ranger with an extended cab- probably the same cab area as your acura, OP, and I had a 10" mtx sub in a small sealed box behind the driver's seat powered by a bridged middle-of-the-road pioneer amp- and man that thing hit SO HARD. could hear and feel everything.

moral of this story is: you don't have to drop major $$$ to have a really sweet car stereo. and if you spend very much tine in your car at all, definitely take the plunge. it's a quality of life issue, brother!

and have fun with the cable routing (that's my favorite part)

I think Im gonna go with a single 12" sub in my trunk with a 600 watt amp or so. I want nice bass that can at times be a bit sloppy/grimy.

Sorry to BUMP but I felt this would be better than making a new thread. Im starting to go out looking for sub(s)/amp setup. A few questions, what hits harder, deeper bass, a single 12" or two 10"s? From what Ive gathered one 12" will hit deeper bass because its a bigger sub and all the amps power is going to one sub. And that 2 10's may hit harder, but theyre shorter and better for higher frequencies. Last question, sealed or ported sub box and why?

Sub size has nothing to do with how "deep" the bass is or what frequencies they play, the driver parameters and box are what determine that. 2 10's should be louder because they have more cone area.

Ported box if you build your own, have one built for you, or if the tuning frequency is advertised, sealed otherwise. A good rule of thumb is subs in a ported box will be twice as loud as the same subs in a sealed box. Or one sub in a ported box will be about as loud as two of the same subs in a sealed box. I say if you build your own, because most prefab ported boxes are tuned way to high and generally sound like crap. There are plenty of box calculators if you want to build your own. You want a tuning frequency of 32-36hz depending on the sub. Most prefab boxes are tuned to 40+ hz. You will peak ~8hz above tuning so a box tuned that high will sound like crap on low notes.

I've had ported subs sound just as clear as sealed at certain volume levels. The box has to be tuned to the frequency specified by the manufacturer. You can use a port calculator to put the right length and always use the biggest diameter port size as possible. Larger port will decrease port noise. This goes for slotted port boxes as well.

Your sub will require less wattage to perform in a ported enclosure.  It will also handle less wattage as well.

Choose the biggest box size specified by the manufacturer for your sub weather it's a sealed or ported box. Pm me if you got questions on box building when u get your sub. I don't mind helping u design it.

Im thinking about single 12", ported box, with an 800+ watt amp. Because having 1 sub is morr spacious than having 2. And ported because i like my bass loud, sloppy, and grimy (and I can.build it for free). I know sealed gives more of a "clean" sound. So one sub for like 140$ and a decent amp for about the same (making to check back of the amp like somene above said) and the wiring. So im looking about 350$ for a decent sound system.

sub:
http://obsidiancaraudio.com/index.php?id=6 ; <-- absolute best bang for buck sub in your pricerange, no questions.

amp:
http://www.ebay.com/itm/Kenwood-KAC-9105D-1800-Watts-Class-D-Monoblock-Amplfier-/200951162435?pt=Car_Amplifiers&hash=item2ec99f6643&vxp=mtr ; (note it is a 900w rms amp, not 1800. I owned a older version of this, they are good amps)
or
http://www.amazon.com/Hifonics-Brutus-BRZ1200-1D-D-Class-Block/dp/B0036B8URK

wiring:
http://www.knukonceptz.com/productDetail.cfm?prodID=KCA-K4 (quality wire, I have used them).

I'd personally go with the hifonics amp above. Any hifonics amp is good as long as it is a BRZ model. Either one of those amps on that obsidian 12 will be loud. If you don't want to spend that much on a amp just buy a used BRZ on ebay, there are a lot of those amps out there. PM me if you have any questions about setting everything up or designing your box.

2 10's need a similar sized box to a single 12, but with your budget, a single sub setup is the way to go. Hell I'd get a 15 if you have room.

I think 800w is too much for a single ported 12" sub. You should pick your sub first and then match an amp to it. Unless you find an amp/sub combo cheap enough.

blah- power handling depends on the sub, not the size

I remember him talking about budget is all. If he is getting a sub which is that demanding for power, then by all means...

oh yeah dude, also to get the most out of your amp you want to wire your sub to the lowest impendence (ohm) your amp is stable at. You can wire a dual 4 ohm subwoofer to 2 or 8 ohms, and you can wire a dual 2 ohm subwoofer to 1 or 4 ohms.
