20 Most Recent American Pro VS1403 Car Audio Amplifier Questions & Answers

Have you moved all of the switches, controls and RCA jacks to make sure that the problem isn't a dirty contact?

Have you tried swapping the RCA signal cable from a working channel to confirm that it's not a signal problem?

Have you swapped a speaker from a working channel to the dead channel to confirm that it's not a speaker problem?

It's unusual that one channel goes dead and the rest work.

YOU CAN USE A UNIVERSIAL UNIT WITH RCA''

You can bridge 2 channels, Not 4. The individual channels will fight each other and one will cook...

I used to have a similar model, vs1405, and it was advertised to have 600w max. Its rms ratings were 260w bridged @ 4ohm. and 80x2 @ 4 ohm.
So I really wouldnt expect much.
I would personally suggest the HiFonics Brutus. Very nice amps for the price, and have TONS of power.

hey i had this happen to me, pull the deck out and move the rca cables to a different channel and see if that does not fix it. i blew out my sub pre out channel in my deck and had to use the rear pre outs. try this and let me know what you come up with. good luck
