07mazda3s Posted July 26, 2007 Report Posted July 26, 2007 I've been thinking of getting a new HU for a couple reasons. It would be nice to be able to play Mp3 cd's, def wouldn't hurt performance of the speakers or sub, stock HU sucks ass. My question is kind of dumb but I honestly don't understand. All the headunits I'm looking at have 4 channels. My car has six speakers and the sub. I know that aftermarket HU's have sub outs, but how would I divide the 4 channels of the HU between my 4 5x7's and 2 tweeters and how do they know whether to play high or low or what?
