Right now, i have two, 12" Blaupunkt Over Drive subs behind the back seat in my QC. Space is cramped and they dont sound as good as i want them to. I was thinking of switching to two 10" Kicker L7 in a custom center console or modifing the back seat to get a larger box for the 12s i already have. Any suggestions on which set up would be louder. I am using a 1000w Sony explod amp. (I know, its sony but it was FREE!!!)

The amp you have wont power them it will only fry them from distortion when you play it at high volume. The kicker L7's have an RMS 3 times what your current speakers have. OD=200rms ea. L7=600rms ea. You have way more potential w/ the L7's. The subs are just small and it seems like you want something larger. If you have the funds go for the L7's, but get a good amp. I would suggest the Kicker 06ZX1000.1 if your trying to stay within the relm of kicker. BTW you would have to get the Dual 2ohm woofers to wire them correctly to this amp.

Thanks for the advice Josh. I looked that amp up and i am a little confused about it. I dont quite understand all the specs. When its says Mono that just means that there is one (+) and one (-) terminal so i have to wire the speakers together right? And when it says 1000w @2 ohms and 500w @ 4 ohms, does that mean if i use subs that have that have 2 or 4 ohms, that is the wattage that will go to them? Sorry about all the questions, i have never completly understood all of this.

ADKwitDAK,
A few things to know if you're starting out in car audio, or audio in general.
A few things to remember: bigger is not always better and big box stores sell junk at outrageous markups. Also, a lot of companies will rate things in "peak", "max" or "dynamic" power. These ratings are misleading and cheap, typically double what you're actually getting out of it, which is called RMS, CEA or continuous power. A few popular companies that rate in "peak" are pioneer and sony. There's really no way to tell which companies rate by what, so when buying you should always look for RMS or CEA power ratings. Another thing, some people say dual voice coil subs are "better" than single, but all DVC does is increase wiring options. Lastly, creating too low of an ohm load will fry an amplifier (creating a 1 ohm load in your case).
You are correct about your assumptions on power in your last post. However, there is still much to learn (and perhaps you already know it, but I'm going to assume you dont). Ohm's Law is the principle to wire up speakers. In a nutshell, the impedance (rated in Ohms) determines how much current goes through a speaker. The lower the impedance, the more power. However, if you wire a sub in a configuration with a lower ohm loading than your amplifier can handle, it pushes the amp to drive more power, which can over-draw and burn up your amp. There are tons of wiring guides out there, and not to be mean, but go google them. There's not enough space on this entire forum to fit all the information.
Check this out:

Josh apparently knows the specs your current subs, but honestly I do not have the time nor energy to look into them. I am assuming theyre single voice coil, 4 ohms a piece. If you wire the subs in parrallel, you will have 2 ohms at the amp. This will cause the amp to push 500 watts RMS (1000W max) to the pair, which is more than adequate for most. However, you have wired them in series, you will make the amp operate at 8 ohm and push about 125W RMS (250W max) to the pair, which is seriously under powered.
I think a 10" L7 ported and @ 2 ohms on your amp would sound pretty good. If money's an issue, you can always consider a single 12" Blaupunkt OD in a sealed enclosure. (Sealed enclosures are smaller).
I'll be glad to try to answer any questions.
Good luck,
Jay

Heres My Current Setup.
MTX Thunderform w/ Alpine Type R Shallow Mount Sub.
This hits very hard for only a .7 cbft box.
But
My friend has a 2003 Quad Cab with two Rockford Fosgate P3's 10's (Punch Stage 3 - 10'') With the boxes from supercrewsound? i beleive... and believe me that hits hard. Hes putting out 1200 watts RMS to both and its enought to shake things in your house from across the street.
For the price... i think L7's are a bit overkill... you'd be spending near 500 on an amp to power them at they're rms...
If your looking for good deals on Kicker Products... Use http://www.sonicelectronix.com
They have the 750 watt kicker amps for around 215 i believe... Good luck with the system.

See, right now i have those Blaupunkt 12s beind the seat right now but i made the box and inch shallower than what would fit so i could put the grill over it because the cone sticks out above the rim of the sub. I did this because i didnt think having the sub pressed against the seat was a good idea. Has anyone had any problems with their sound being muffled or distorted because of the sub being pressed against the seat?

Sean, what kind of amp is your buddy using to run those P3's? Im assuming the amp he has is kind of pricy. What would be a sub - amp combo comparible to that?

Hes running a Kicker ZX.1500 Amp (I believe) Which is technically 750 watts to each channel.
As for comparable... if your putting it in your dakota i would go for the following setup:
Try to get a box similar to these... but with at least 1.0 cubic ft of space. These are a bit to small to handle any real power without falling apart.
http://www.supercrewsound.com/shop/detail/11/91.htm
Any custom audioshop will be more than glad to build you an awesome box!
For a truck... all you really need maximum.... would be around 600-800 watts to really shake things up.
For a budget system this amp will handle whatever you run off of it:
http://sonicelectronix.com/item_8845_Power+Acoustik+PS2-2600.html
Its reasonably priced and a friend of mine has it... very strong and great sound quality.
Power that to two 10'' Kicker Comp subs... or something in the 100-200 dollar price range ... and your set!
Make sure teh subs have at least a 500rms though.
The kicker Comps are awesome subs.. they hit hard.
