I just got a ida-x303 head unit for my 2004 saab 9-5 sportwagon with as-2 sound system, and it works fine, until I hook up my amp, my amp can be on and stuff just fine but when I hook up the wires from my head unit to my amp (240w) it makes a squeeling noise in all my speekers that gets higher in pitch as my rpm's in my car go up. The power ground and remote can stay hooked up, but once the signal wire goes in it makes that sound. what is causing the squeeling noise? What would fix it? And how much would it cost?
My car audio system makes weird noises when my amp is hooked up?
