[QUOTE="hispls, post: 8354972, member: 614752"] OP, it's really time you do some troubleshooting to isolate the problem. Trust and believe that any audible noise is unacceptable and you should NOT be paying to make that go away (unless you're buying equipment at walmart). If the shop is just trying to up-sell you on new equipment RUN away from them. A simple process of elimination should be able to isolate the source of your problems by just pulling wires and listening for noise. I'd like to say first of all, if your battery terminals are corroding clean those up really good and use either some Vaseline or dielectric grease on them to keep corrosion from returning. Have you removed the RCA cables from the amp then listened for the noise? Remove at the head unit, remove at the amp. Where is the amp grounded? Have you upgraded the ground from the battery - terminal to the vehicle frame? This should NOT cost you money to fix. Either the install is bad or you have a faulty piece of equipment that should be warrantied. Buying snake-oil wires is NOT going to fix this. [/QUOTE]
