Can't Get Headunit out of Protect Mode

[Ryguy588 10+ year member]

Okay, I've done about 4-5 set ups in the last couple years and have never had a problem.

My Father sold his old car and got a new one. He did however keep his old setup. I recently went to install it in the new car and the head unit (Kenwood) Keeps going into protect mode.

It is the identical setup that was just running. I have a great ground, direct power, and everything else seems to be wired correctly.

The deck will turn on but within seconds goes into protect mode. If i run the headunit straight to the speakers it works fine. The second I try putting the amp in the middle it goes into protect. If I pull the RCA's and start it up Its fine. Connect the RCAs and protect!

Any ideas?

What kinda amp are you using? If you don't have it you can probably just download a pdf manual. It'll give the basic steps to troubleshoot why it's going into protect.

sounds like a bad rca or amp

Amp is good. RCA could be bad but three different cables and two different amps giving same effect. Never been this stumped. Feel like pulling it all out and starting over.

if the deck works fine not plugged into the amp then its not the deck.something with the wiring
