[QUOTE="Jimg, post: 8795939, member: 676695"] I have a 2010 camaro ss running a jvc 750bt a us acoustic Barbara Ann only using the two front channels on the door speakers sub amp is a ct sounds ct1500.1D subs are two 10 inch Dayton HO here is the issue I am getting zero noise on the 4 channel amplifier or the door speakers so we are good there I am getting some alternator RPM noise on the sub amp playing throng the subwoofers the battery on the camaro is in the trunk of the car I am using stinger 8000 RCA cables from the head unit. I am using 0 gauge OFC wire going to a distribution fuse block then using 4 gauge ofc wire going from the distribution block to the amplifier I am also using O gauge wire going to a distribution block direct from the negative post on the battery. both amps are powered off the same distribution block both amps are grounded on the same distribution block both amps are located real close together on an amp rack What would be the issue with the noise? Why am I getting it only out of the sub amp and not the 4 channel how would you fix the issue 1. Possible run a second ground wire from the battery negative to somewhere else on the car for An additional ground 2. Ground loop isolator? [/QUOTE]
