I purchased one of these mounting plates and subwoofers from this site
WWW.TOYOTAWOOFER.COM and I got to admit it is pretty cool.......just hooked it up with a JL 250/1 sub amp and it kicks........the 8" Credence woofer is the toughtest 8" sub I have seen other than the JL 8w7 but that thing is from another planet..........it fit great , and is stealth , the seat folds down with out touching it which is great so my kids wont crush it............TACOMAS , check it out...........
