I guess you stuck that beneath the rear seat... You must not have read this guy has a crewmax...JL just rolled out a new W3 10" JL shallow mount Sub, has more flex / range then there 13". I'm breaking one in now and it sounds great so far, hits low and kills the 13". I know a guy that put two in his truck.. mine shakes everything.. I'm pushing it with a 400 watt RMS alpine Mon amp. i'm also using a 4 channel Alpine for the other speakers..
and that box has been out if it is the one I think it is... I am not sure, you have no model numbers or anything... hmm.
