I just wanted to make sure that if a headunit doesnt come with a sub preout, is it ok to use the rear preout for your sub amp? Im pretty sure thats what you normally do for decks without sub outs, but double checking my info. Thanks.

most head units without a subwoofer pre-out have an option to change the rears to a sub output. check the head unit manual to see what it says

ok so it seems that you are right except that it says the front preouts is switcheable to sub outs, but would i then use the rear preout for my fronts? Would it understand the difference in signals and my rear would become my fronts or what?

I like using HU with Sub Preouts cause most units have the option to cut the sub off from the deck itself...

yes old old old model pioneer decks have the feature on the front pre-outs
run your fronts from the rear pre-out and with the deck off, press the audio button and hold it, then it comes up with another menu, change the output from full to sub.
