ok...so I thought I had a duff amp.
Amp was a cheap unknown brand and my second hand but like new Pioneer headunit was like new. And the best headunit I have owned or bought.
Turns out to be headunit...but I am hoping someone can shed some light on fixing the issues/headunit.
Basically with amp phonos plugged in to headunit, one for sub, one for shelf speakers, with volume on 0 and ignition on, there is a high pitch buzzing from speakers and low pitch grumble from the sub.
Engine on and this becomes a VERY loud buzzing from both.
With just ignition on, if you operate fans or indicators or wipers, you hear them operate via the speakers...if that makes sense.
I assumed amp was gone...so got another. same problem
I tried new earths on both amp and headunit, new phonos etc...
then plugged in an old tatty slightly buggered headunit...and nothing. No buzzing at all.
I am gutted
any suggestions?? the model of headunit is Pioneer DEH-P70BT
I have ordered one of each of these to try:
