FIRST COMMON PROBLEM:
recheck your ground connection. Make sure that your amps ground wire is securely bolted to the metal body of your car. Not only that- yo uhave to scrape or use sandpapar to make sure that the terminal is touching bare metal..
this is a very common problem. Nobody realizes that the ground connection is just as impoarant as the power connection...
Next unplug youir rca cables from the amp. If the heartbeating goes away then mabye you have a rca cable or deck issue. If you can wiggle the rcas at the amp and make it heartbeat more or less.. then perhaps the rca terminals have come unsoldered form the circuit board...
in any case without me looking at it personally this is about all i can tell you. CHeck your connections and GOOD LUCK!!!!!

It means that the subwoofer is blown. The red light is called the Protect light. Disconnect the speaker wire from the amp and then turn the amp on and see if the red light goes away. But if as soon as you hook the speaker wires back to the amp and the red light turns on that DEFINATELY means the sub is blown.
ohm load check the way you wired it if the amp can handle 1ohm make the sub 1 ohm dule 2 ohm subs hook the neg from one coil to the pos on the other then take the empty neg hook it bridged to the neg on the amp and empty pos to the pos on the amp also check to see if you hooked it up bacwards subs dont hit hard when they are beating in and not out
This is an internal power supply failure - most likely a failed capacitor or bad ground trace.. Your amplifier requires repair. To verify this - remove the RCA cables and if the "heartbeat" is still present - take the amplifier to a local repair shop that specializes in car audio and tell them your symptoms.

sounds very similar to something that has happend to mine. if you check the fuses in the amp and they are fine, i recomend replacing the fuse in the power wire. if you are using the glass tube type fuses, sometimes the soldering at the endcaps melts, but the filament doesnt pop. the fuse appears to be fine, but isnt. that happend to me a few times. i had to upgrade to ANL type fuses
Actually. I don't think you have to wire a remote switch from the radio to the amp on this product. This powered subwoofer supposedly has automatic signal sensing turn-on circuitry. I have the same problem. So I think I'll try to just hook up the power (to the battery), ground and the + / - speaker wires to one of the back speakers in the car and see if that works.
