[QUOTE="iowabucks, post: 8161232, member: 625364"] Hey everyone, I am a DIY'er, but have pretty basic knowledge when it comes to wiring amps or subs. Right now I have a Sony CDX-GT510 that I am wiring a sub to with a Cadence Amp. I also am going to wire up an Alpine KTP-445U 4 channel power amp, which is kind of a mini amp in a way, for the 4 Kenwood cabin speakers. The Sony HU only has 4 RCA outputs along with 2 more RCA inputs. Remember, I said my car stereo wiring knowledge was pretty basic. So what I want to know is how do I wire both subs up with the RCA's when there is only 2 sets of rca outputs on the HU? One pair for audio out front, and one pair for audio out rear? I see my HU can switch the rear RCA outputs from rear speakers to sub. If I switch it to sub, how can I power all 4 cabin speakers (front and rear) from the amp. I don't want to be limited to only powering 2 cabin speakers and the sub. How can I use an RCA splitter to get all 4 speakers and the sub (on a separate amp) powered at the same time? I know the HU is a little old and might not be capable of doing what I want without some kind of balance/fader limitations. How do I handle this? [/QUOTE]
