What would be some nice Subs that wouldn't sound bad in the trunk? Maybe just one 12"? HELP!!!

 

It all depends on what your wanting as far as sound. 1 12 inch sub will give ok performance with more of a rolling bass but what matters is what type or brand of sub along with what amp you are planning on powering the sub. If you want good sound inside the cabin without overwhelming bass I would go with 2 quality 10's in a nice enclosure made to spec then get a nice amp to push them. The 10's will not over power the cabin components like a 12 inch will so it will be easier to tune if your not upgrading the inside components.

 

i had 2 12" kickers in my trunk ... sounded great inside but the trunk rattled, if you want it to sound clean you gotta use dynamat
