[QUOTE="Motovet, post: 2471445, member: 570186"] Dammmmmit! It is not the amp. I tried another amp...and same **** noise. If I disconnect the power to sub amp all is quiet. I located the ground from the sub amp to the ground for the fronts, so that can't be a problem. This is what I have found prior to trying another amp, and re-grounding 1. Everything hooked up and home player off front amp = noise only comes through sub. 2.Everything hooked up, but RCA's off front amp = noise only through sub. 3. RCA's off all amps = less noise only through sub amp. 4. RCA's on front amp only = less noise through front speakers, and sub. 5. RCA's all off HU, but all connected to amps = noise through front speakers and sub. 6. Sub amp not powered = quiet. 7. Only sub amp powered = noise through sub. 8. Only sub powered and run off home player = noise through sub. 9. Different amp, and verified ground = all of the above. Where could I possibly be picking up this noise? Also this is the second HU with same results.... AND this noise is constant...key in any position, and no change with engine running. [/QUOTE]
