im not really an audio guy...i would say 1 12' or 2 10'.

you wont hear the speakers with all that bass and unless your going go crazy in do a nice custom fiberglass enclosure then all you are doing is adding weight. Not to mention the price of 4 subs and the amps needed to run them wont be cheap.

2 10' under the front seats would be cool.

yeah.....i hear ya...i think im gonna just start out with 2 12" i dont know if i really want that JL thing its cool and all but too pricey.....

two 8s under the seats would be nice. i wouldn’t get 2 12s unless your gonna go and put the sound insulation all over the car. if the speakers are making it rattle then subs will shake the thing to pieces.

true.....so what do u think is it cheaper to build a box for a sub or buy one...

-some other stuff

those are sweet but way too expensive lol

85 for a hidden box is not bad at all.

yeah but i dont know what i wanna do yet......what is better single voice coil double voice coil or none??

How much for a reasonably priced trunk sub w/ box?

im gonna get the 12" infinity reference sub to go with the speakers i have in my car already...

best buy usually has something running for a sub and box. then ya need an amp. expect to pay 300-600 depending on brand and size and what not

lol those best buy speakers that they have those deals for are ____!!

Forget that. My system is fine without the boom.

hahaha i cant wait till you hear robs system shannon you wont be able to hear for a day and u should wear a hat cause ur hair stands up in his car lol

My best friend's bf had a few subs in his old car and I had to listen to it allllll the way from San Diego to Vegas and alllllll the way back. My hearing has never been the same.

im not really an audio person either. its nice and all...but i would rather put the money into other parts of the car. to each there own.
