Will someone please give me an idea how I should hook up my outputs from my alpine w235bt..I have a mid size Toyota truck so I have infinity 4 1/2 in the dash and 6x9 for the rears..and a single polk audio 12 sub..I have 2 infinity amps..a 4 channel for my speakers and a mono for the sub...Soooo I havent got my w235bt yet but it looks like there are only 2 pre-outs..a sub and a front speaker..Of course my least effective speakers are my fronts..Soooo please post some ideas on how you would hook this up..Thankyou..jeff...cold in iowa
