Bit of an odd one..

I've recently fitted an Amp to run my 6x9's (just an old cheap one kindly donated by my step-brother) this is it:



but since doing it, when the H/U volume is turned down or on low i get strange noises through my speakers.

1. A noise from the fuel pump priming on ignition
2. A horrid noise when i start the car.
3. A whining noise that gets higher with revs.
4. Clicking from the indicators.
5. A whining when i put my windows up.
6. When i use my washer jets.
7. Also an odd noise that seems to originate from the H/U itself when playing CDs and spinning them up or changing track.


When it was fitted i ran the battery live down the passenger side, and the RCA's down the drivers side as i was told to do this to minimise interference.

The amp is earthed underneath the rear bench and is screwed to the rear seat back, i've checked the earths for the amp and for my H/U and all seems fine, so what else could be causing this? and what if any, is an easy cheap solution?

Cheers

It's electrical interference caused by the ground wire.
Either fit a ground loop isolator, or run amp earth direct to battery.
But if it really is a cheap amp, some interference is to be expected, not that much though.

I second the ground loop isolator, easiest way forward and only cost 5-10 quid
