So I have a new audiopipe Bluetooth headunit I installed in the boat. Im getting TERRIBLE static from it. It is not type of static which I usually associated with a bad ground (engine whine etc..) but a constant static that gets louder as vol goes up. It does not cut off if you set the headunit to 0 also.
Bad static on all sources (Bluetooth, AUX, FM/AM)
Popping noise when boat is turned off
HU Yellow to boat harness Yellow
HU Red 12v+ to boat harness Red
HU Blue remote to boat harness Blue
HU Ground to boat harness Black while also trying to move the ground around (ground block, and AUX battery).
Steps to correct issue:
Replaced RCAs from headunit to EQ - static
Ran RCAs directly to headunit to by pass EQ - static
Ran a different amp - Static
Ran different sets of speakers - static
Moved HU ground from harness to Aux battery - static
Moved HU ground from harness to ground strip under dash - static
The only time I got no static was if I bypassed the headunit as the source, using it to only power on the amps and hooked the iPhone directly into the amp (RCA to 3.5mm).
Am I correct at assuming more than likely the unit is bad?
Thanks for any help ...
