If a headunit only comes with 1 set, im limited to a 2ch amp yes but is there anyway around this? Like anything aftermarket out there to be able to use 2 or 3 sets of pre amp outputs on a headunit that only has 1 set? Or are you **** outta luck and stuck with what ya got?

 

there r a couple of things u can do either get a cross over or get splitters and turn it into a 2 channel i did it in my old ride its cheap but if you set it up right it will thump,u can buy an x-over where u can input your 1 channel and put out 2 or more for more amps,i still like rockford fosgate,the old school is much better than new
