Help!
I have an '05 Murano SE with the Bose system and a PAC OEM-1 with the NIS-2 adapter and the ADD-RCA harness hooked up to an Alpine 4 channel amp with 4 Infinity door speakers. I have ran all new wiring to the door speakers and the rca cables from the PAC are on the right side of the vehicle while the amp power is on the left. The amp is grounded to the common Nissan ground bolt behind the rear seat.
I just got finished installing the Alpine amp tonight and I am using the Bose amp to power the Bose subwoofer only. The problem is that I have a warbling sound in the rear speakers, sounds like birds chirping. I switched the rear rca cables at the amp to the front channels and the noise transfers to the front speakers. I have adjusted the output on the PAC so that the front levels are both at about 60% and one of the rears is at about 20% and the other is at about 70%. If I set both rears to the same level the warbling, bird chirping comes back. It doesn't matter whether it's left or right that is set lower but I can't set them at the same level like the front.
I tried unplugging the Bose amp right at the amp and the warbling sound is still there.
I'm almost ready to chuck the PAC OEM-1 and run from the Bose speaker outputs on the Bose amp into the hi-level inputs on the Alpine amp.
