i recently had a front component speakers put in doors hooked up to an Amp with the Factory Head unit. There is hissing sound coming from front speaker now with Stereo on or off. IT only goes away if car is off and running system off battery.
The shop i took it to said i need to replace the HU with an aftermarket stereo to fix the problem.
My question is , has anyone had a similar problem? Do i need to replace the head unit or was it just a bad install? And should i take it to another shop to have looked at? Any suggestions would be great.
This is a bad install, but a hiss that happens whether the radio is on or off is not because of running the RCA's with the power wire. Sounds like they wired your amp turn on to a source that stays on whenever the ignition is on. That is not correct. This is why I frown upon wiring the remote to the cigarette lighter.
Also, you don't need a new head unit. You just need your amp remote turn-on wired to the proper wire.
