Scooted back all the way--would like more but nothing I can do:
The sub box doesn't go back as far as I would like it to, but that's my fault. When I put my deadening in I also put in 1/4" carpeting from Lowe's (to help with road noise). That adds quite a bit of thickness to the contours of my floorboard, so when I try to push it back all the way it just won't go. It's not too bad, though. Plenty of foot space---even I crawled back there and I'm 6'5".
Can say one thing that I learned today:
The dog loves having "her" seats back.
New amp came in. Finally something goes right---hooked it up where the defective amp was and it worked perfectly. Finished up the wiring, cleaned it all up, and reinstalled the seats....
The low end difference is amazing. It hits harder, louder, and is more crisp. Such a more natural sound than the preloaded MTX.
Just to get an idea of the difference (sounds like crap on camera):
Rock: P.O.D. - Youth of the Nation
Rap: Young Jeezy - Welcome Back
That's as far as I've gotten in the last three weeks. I'll try to update with some better (daytime) photos and vids.
