the only time i have had it blurred where you couldnt read anything and spinning rims looked like a fan in a strobe light was with 3 T2 15's and it was about 155 db.
Does anyone have specs for a spl box for a rockford t2 15"..i made the one from the specs on the rockford site..but i was just wondering if theres one built for spl thats tuned lower or something..any ideas would be great thanks
