Not an expert but I did install it and did my research each step along the way.
Recently my music stopped working. Sometimes I connect to the Bluetooth and it works again.
D4S JP84
Skar rca cables from head unit to the amplifier
OFC wiring
Running 4 channels to 4 Rockford Fosgates P1683 130watt 6x8 3 way.
Used ferrules
Multimeter says
Battery is less than a year old
No inline fuses out
Getting 14v to the amplifier
Ground was a little funky but sanded and reattached to sanded bare metal. Still getting a solid
Remote wire is giving a reading
Amplifier is in protect mode.
Tried disconnecting everything and reconnecting after 30 min - protect
Disconnected speakers and inputs leaving power ground and remote - protect
Might have been on the wrong setting but didn’t feel like I was getting a signal from head unit to inputs.
All rca and speaker wires passed continuity check.
I’m down to either a bad amp or head unit not giving signal any easy way to check. I do not have another amp to check with. And thoughts. Why sometimes yes and then no?
When I started looking into it, it’s played for over 1hr no problem then went out again.
I’m stumped
