I'm new at this and have run out of ideas.
I have installed the amp power, earth and remote lead. The light comes on when the Head Unit is switched on but I am getting no sound from the speakers.
I have checked the gain on the amp, made sure it is not switched to bridge and checked the phono leads to make sure they work.
What else is there to check? Can I put a multimeter on the Head Unit phono out sockets to check if there is any voltage?
