Spooner: I have the AAS in my RL. All I want to do is kick up the bass with a sub. What do I need to buy? Thanks!
For the most part, just an amp, a box for the sub, and make sure you're reading what these guys are doing to hook it up. So you'll need some sort of adapter to go from speaker wire to RCA jacks. Or you can get an amp with speaker wire inputs that you can take from the rear speakers. Please make sure you buy good quality wiring, it's not cheap. My power wire that runs from the battery up front in the Camaro to the amp and subs in the rear was about $100 for a 7' length. It's about 1/2" thick too.
If you roll into a smaller car stereo shop, they'll help you alot. As long as you know enough to keep them honest. There are some spefics that you have to adhere to, like the size of the box, the power from the amp to the speaker, the amount you can bridge the amp, etc.
The easiset thing you can do is to buy a set of 10's, or 12's, that are already installed in a box. If you're not planning on really pounding hard, then one 10" or 12" speaker will be fine. Choose a good brand, don't be afraid to pay some cash to get a speaker that will last. My 12" JL's are over 10 years old and work perfect still. The power of the amp you want is balanced by the amount of power the subs can handle, and the amount of power you have going to the other speakers, so they aren't drown out. That's my issue in the Camaro, could never afford another amp for the 6 speakers I had up front. Again, buy a good brand of amp for the subs, while a $50 amp and a $200 amp may put out the same power, there are alot of differences within them, the most important ones, to me, being the durability of the power circuits, and the noise level of the circuts. Without researching all of your choices deeply, just make sure you get a decent name brand.
Check out the Crutchfield website for some good DIY stuff, and they have some pretty good explaintions of what the different stuff is good for.
