Have had my car for 7 years, and finally installed a new headunit, and wired up for a small amp for subs in the back. Had JL Audio separates left in by the previous owner I discovered front and deck speakers back, so sounds much better than stock speakers.
I used to have a 94 Grand Prix with a JL Audio dual 10" bandpass box. It was nice as we moved the single port from up top, to firing back, so it lined up perfect with the ski hole. This was great, as no sound was in the trunk at all. Of course they don't make that model anymore.....it was back in 94.....
I'm suprized I don't see more setups like this. Most are boxes just firing into the back of the trunk that just have to rattle the crap out of it.
