The little blue wire on the head unit labelled p-cont? Yes.Have you wired the remote cable to the head unit from the amp?.
The head unit sends a signal down this to the amp each time its turned on/off.
Checked the fuses on the amp?.
A good old fashioned wire coat hanger is helpful in pulling wires too.
You can earth anywhere on the body if you rub back to bare metal. Vaseline will help conduct the current too amongst other things.
I've tried all suggestions but amp still not working, even tried a different amp still no joy. Could there be a problem with the p.cont wire? How can I check that?The little blue wire on the head unit labelled p-cont? Yes.
Fuse checked and ok.
Thanks for all the adviceT:
Hi mate, tried all that, what should the output read for the remote wire?Start with the fuses. Check the potentiometers on the amp aren't all the way down.
Get a multimeter on the job mate, switch to ohms and check if there's any resistance between amp negative and van chassis, this should be as close to zero as possible if the amp is earthed.
Check if the HU remote wire is outputting a voltage, check this at the back of the head unit, then connect it up and check it at the remote input at the amp.
Failing that you could use a very small wire to jump from the 12V input into the remote bit. Check the manual before doing this though as I don't want you blowing anything up. T:
This should give you a better idea of the state of the amp
