i can't say for sure the OP fits in this category,but it seems that way.

if you want to build an SPL system for competition,that's cool.i used to be into that scene,and i still enjoy car audio.
if you want "some bangin bass,son",so that you can pull up beside me at a stoplight,making my two year old in the backseat cry...that's not cool.

i guess the whole tone of his post-that "i wanna bust out mah back window" type thing is what gives the impression he's the second type of person...not to mention the lack of any kind of punctuation or sentence structure.
if the post included some kind of target sound level,a rough budget level("money is not a problem for me" does not count.if that were the case,get the Fishman to build you a system),how much room you're willing to give up,etc.,i'd be more inclined to give advice.

take your car to one of the audio shops around here.Custom Auto Sounds or Audiotronics would be my choices.i really don't think there are any shops in the area that are top level,but they're capable of making a lot of bass if that's all you want.tell them what you want,and how much you have to spend,then let them figure out the best setup for you.

two Kicker competition 15s and a Precision Power a1200.2 amp were enough to break the urethane on the back window of my coupe about 10 years ago.it was painful to sit in the car.the box was tuned to play down really low,and still have very good response and sound quality.one 15" or two 12" subs with a good amount of power should do it.i still ran the stock alternator-never had any problems,and that was also running an a600.2 to power the front stage.
