Problem

[Jdog123]

I have a 1600 amp running two subs off it. Getting a whining or humming sound coming from the subs. I check all grounds and their fine wonder if it could be the head unit or alternator or rcas wires. Need help??

Give us more info Jdog. What brand and model amp is it. What subs. Tell us about the grounds that are fine. What kind of deck do you have. Where do you have the RCA's ran. Does the whining seem to wax and wane with the RPM of the engine?

Then do this:

Unplug the RCA's at the amp and see if the humming persists without an audio signal. If it does its likely something with the power or ground, ground being more likely. If not we are now pretty sure its an issue with the RCA's/deck/rca inputs on the amp.

Try this and get back to us. Dont be afraid to PM me jdog.
