At the point we quit for the day we had it playing. This box hit the lows very very well. Turned out very well considering it's a trunk car with no folding seat. We'll have to deaden the roof, floors, and get the doors some more later down the road as well. Also going to be adding a battery soon of course. But for now, this has turned out pretty well.
Oh ya, of course I'll get vids of this today at some point, so keep your eye's pealed for that as well.
I'll update this build log when we get the amp rack finished as well. Thanks for looking.
