When running multiple amps you need a relay most of the time for the remote wire off the radio this is because the radio was built to power one not multiples. one 12 volt relay may help .check local car audio store. also when hooking up relay it has to have a 12 volt power wire connected to it usually the center pin on the relay is your connection for the power wire the you connect your remote wire from the radio to the relay then connect each amp independently to the relay. Hope this helps write back if not . and if so leave feedback

it sounds like you have a short someplace. also, if you have a multimeter, check the voltage coming out of the speaker terminals of the amplifier. if the voltage is higher than 4 or 5 volts, the amp is probably bad.

Amp doesn't come on


Hello rheabarb,

You did not say whether or not you checked the wiring going to your subs. Many times, a shorted or grounded speaker wire will cause an amp to fail. And if the amp powers up OK with the subs disconnected, I'd suspect one or more of the wires.

Hope this helps.

Amp works but no sound from sub


Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.

Car amp's stopped working. Putting out a heart beat sound through subs but no bass.


could be low current ,disconnect all power including ground for 20min N.B most amps will seem to be shorted at output but this is normal due to damping ratio.

Sub does not fully work


My guess is that one of your subs has a damaged voice coil, which acts like a short circuit to the speaker outputs. If you put an ohmmeter on the speaker terminals you should measure a resistance of not much less than 2 ohms (assuming you've wired the VC's in parallel). If you measure a significantly lower resistance then you have a damaged subwoofer.
