Hi guys! I'm new to the forum and need some help. Here's what I've got. I have a high pitch noise from the speaker when vol. on HU is at 1 it doesn't change with engine RPM's or HU vol. if I turn the vol. up I can't hear it anymore but it's driving me nuts.

HU alpine 143bt

Components RF prime series

Subs RF r2d2-12 x2

Amps RF r500.1 subs

RF R300.4 doors

RF R150.2 kicks

Mall wiring is sky high 0 gauge to mini bus bars 4 gauge to amps. My ground from the bus bar is going to the frame(37" long) 14 gauge to doors.

Big 3 well 4 I have one ground going to the factor location and one to the frame

Does it make the same noise with the engine running and shut off, or just running?

Double and triple check all connections especially grounds.

I like to bench test my amplifiers to make 100% certain they do not have an issue prior to installation.

Pioneer AVH-X491BHS

PPI PC 4800.2

Only when running

Amp have been pulled and bench tested with no issues.

I have also disconnected the speakers and connected a test speaker to the amps and the noise is still there.

Hooked my iPhone directly to the amp with the same noise.

Amps are daisy chained

Can noise be introduced through the power wire ?

Reason I ask is my wire follows the factory harness from under the hood, down the frame rail up through the floor

If I turn my amps all the way down it goes away but once I move the gain pass 1/8 turn it comes back
