I have just wired up my amp as stated on the instructions. Connected to the battery and gounded to the Chassis (I think) all fuses are in place and the remote power on cable is plugged into the antenna aerial wire on the HU. Speakers are connected to the correct terminals. When I turn the car on and fire up the HU I hear a noise from the speakers connected to the amp as though something is turning on but that's it. I get no other sound through them. Can anyone help. This is doing my head in!!!
Check all input & output signal cables and connections. Then test your speakers with an ohm meter or by connecting to a home system. How did you put the speakers in, where they in a box or somewhere they could hit some metal and ground out? Also what does the noise sound like? Does it just pop or is it a whining noise? Does it do it with the car off and on?
I did not see you mention hooking up the RCA cable (wich carries the signal that produces music) to your amp from the HU. Did you do that? Cause otherwise all you have hooked up is power! Some wire kits only hook up power, you have to be careful when buying them. Let me know if you have the RCA cables hooked from HU to input low (amp). good luck.
