I got one big ass box that replaces back seat in a jeep. It does in fact double up as a seat and has seat belts on the whole works.
Box is meant to fit up to four 12inch subs with room on the back for mounting of EQ, Amp,etc...
I paid 200 for box but desperately need to get rid of it so im open to offers.
This box will set of alarms of parked vehicles while driving buy.
