New noises in System

[jcurto]

Ok first I am going to explain what is in my car and then explain what is going on. I need serious help though. I have a 2003 Mustang with a JVC head unit/DVD player, single DIN. I have 1 1000 watt ALpine AMP connected through the speaker wiring for the RCA. It is powering two Rockford Fosgate T1 12's. They sound good and arent the issue. I just installed a 1 FARAD Stinger Cap. and hooked up two alpine 4 channel amps. I only had 2 preamp outputs on the head unit so I connected those to one amp and then connected rca cables from the output on one amp to the input on the other amp. one amp is powering 2 6x9's and 2 6 1/2's and the other amp is powering 2 5 1/2's. Connected to the head unit I have 2 sunvisor tv screens and I have an ipod connected to the back of it and an xbox. All is coming off of an Optima red top battery. My issue is that when I switch to my ipod from the radio ie the aux input I get a high pitch squealing from only the 6x9's. It gets louder when I accelerate. Everything is wired with distance between wires and grounded correctly. I tried maneuvering the rca cables around and between channels but the squealing was still there only in the 6x9's. It has always done it even with my old amp. The amp i have them connected to now is literally brand new.

re route the muffler to the interior of your car to create maddddddddd dddddddbbbbbbbzzzzzzzzzzzzzz and send out an optimal sound wave canceling out he squeal it's happening because of how much extra power your caps making!
