I just hooked up 2 brand new Fosgate Prime amps. I took out a good, working amplifier and used the same wiring. Both amps are going into protection immediately. I have a hard time believing that both amps are bad. Here is a rundown of my set up and what I’ve done.

-14 Fusion using stock radio. I use a line out converter with a remote turn on. I have used this for the last couple of years.

Pioneer component that worked as of 10/19/19.

Brand new IDQ 12 that I haven’t listened to yet.

KnuKoncepts Kolossus ofc 4 gauge power and ground wires. KnuKoncepts distro block and fuses too.

With all wires connected, amps go into protection.

I unhooked all speakers and rca cables, still in protection.

Unhooked both power and ground wires to check for stray strands. Made no difference.

I get 12.56ish volts at amp terminals with ignition off (testing across + & – ). I get over 14 volts with engine running.

With remote wire connected, I noticed that the voltage reading drops to about 9 volts. I swapped out my line out converter for a new one and the voltage issue remains.

If I remove remote wire, voltage goes back to 12.56ish.

What is the deal with the remote causing a voltage drop? I have a feeling that is the issue, but I’m not sure what’s causing it. The line out converter is right next to the amps, and the wire from the remote to the amps is a short run (less that a foot).
