no, i dont have ANYTHING hooked up now. I tore it all apart to install sound deadening. I install B-Quiet EVERYWHERE and im looking into a good sound dampener now, then carpeting (but the carpeting depends on the system I am installing.)

The thing is that the subs that are in the hatch arent going to get the best "sound" they will only give a good "thump". (the current system leaves just enough area for the box to fit within the hatch confines and kinda seals it off, with enough room on the sides for air flow. I cant hear them at all as far as sound quality goes, i have them setup to only pick up bass levels and no real low end sound.
IE - they dont give ANY musical sound except a punch.

I have 2 6x9 and a 2 6.5 for the sound quality - and they give great quality sound
