This is my current setup... I actually have a 15 that i'm going to put in it




As for what was already said.. Yes - top down - can't hear it that well..

Therefor i'm taking one of those silly seats out of the back and putting that F'er in.

Going to take the one out directly behind me - therefor when if I ever wreck I will be trapped behind my steering wheel and subwoofer -(joke).

I didn't buy this car for it to be a passenger car.. but - as I have kicker door speakers and its wired to a pretty good 4 channel - it sounds really good at high speeds with the top down.. I just lose the bass when i'm going above 50...

But as for installing something in your trunk - from my pictures should give you a idea of what you can do with the space provided.. That amp in the picture was what came with the car - I have a better amp - which makes a great difference, and it's a kicker 12... Not a bad setup.. Hope that gives you something to think about

FYI Thats a 4 ohm kicker 15 , being powered by a P1000X1bd now... Just need to drop the box in - the dimensions are perfect to fit that space
