Waddup playas, so I just had a pioneer 1200x4 amp installed in my car the other day(GM Dx874?). I got after market basic focal components in the front and coaxial’ in the back. When I turn the music up on my Pioneer Headunit(AVH-1800) the front speakers will play up to about 15-17 and then cut out completely if I play it higher than that but will come back on when i lower it again. The rears however don’t get affected. I checked the RCA’s and wires on the amps and in the back of the head unit. Any ideas what it could be?
