I currently have an Alpine 9813 HU, if i added a in-dash cd/dvd (Alpine IVA-D900) can i or is there something that would let me still be able to use both, as if i didnt want to always use the screen and just the HU for sound etc? Something maybe that can split the RCA's to be able to go into both? i dont really want to get rid of my HU, so i was thinking of an option if i get a good deal on the IVA-D900
you want to use two head units with one set of amplifiers? Look for a Sony XA-39. it's a small electronic switching relay box set up to take inputs from two head units, and go to one set of amps to avoid feedback. you can't just use Y splitters for this.

essentially the RCA's go from the units to that relay box then into one set to the amps?

ok, i looked up what it looks like, but then how would you be able to use the subs with both? only front/rear capable, or so it seems (or would you just buy 2, and then do the speakers with one and the subs with the other)
