20 Most Recent PPI PCX-280 Car Audio Amplifier Questions & Answers

If you look at the speaker hookup it will say bridged and have a line going to the two that you should use....If it doesnt then it might be an amp that you cant bridge

make sure the remote wire from the deck is in the amp but move your ground wire to a new solid metal location you may have to scrape the paint surface where the ground is going to go but it will stop protect mode and run properly (make sure to bolt it down by its self no other wires just the ground from amp) also make sure the ground wire is bigger than the power wire
hope this helped

have you checked your speaker connections and any other connection for shorts or multiple ground loops. cause that will definately cause the protection mode.

the remote wire goes in between the front speaker connects. the extra spot in the middle.

Try a place online called Allied Electronics. I use them all the time things just like that.

Sounds as if you may have a bad ground. try running an external ground from the radio to a bare piece of metal underneath the dash.

you can try to open google.com type the model and diagram
