[QUOTE="Badbowtie7, post: 5446733, member: 606035"] I am in some dire need of answers. I just installed my audio system in my 08 Silverado, 2 10" subs on its own amp, then a 4 ch amp for my door components and rear pillar 4x6. My head unit is a Pionner Avic N3. I am using the sets of pre-amp outputs from the back of the headunit. I have all the wiring set up and connected to the proper wires and rca's to the amp running my subs. But here is where it gets tricky, then i plugs the rca's from the headunit into the amp running my highs and mids. When i do this i get this ear piercing noise from all the speakers. For some reason when i plug those rca's in, i get the awful feedback. I tried using the rca noise cancellors, but that only makes it worse. You can also here the engine reving in the speakers when you rev the engine. It's not the amp, not the cross-overs in the doors and they are new rca wires. I am stumped. I was wondering could it be the wiring harness that holds the rca wires, could that be bad. I am looking for answers, if there is anyone out there that can help me out, it would be greatly appreciated. Thanks, Mike [/QUOTE]
