SOURCE: protection light keeps comin on

Unfortunately, P/A does not release schematics - even to repair techs. You have to find a knowledgeable repairman, or ship it to P/A.

1-888-990-1236 for support, and RA# info.

Plan to be without your amplifier, as NEW WARRANTY repairs are backlogged approx. 6 mo.

Rule out external problems by hooking it up to an isolated bench power supply.

If planning on doing your own repairs, see this site for info.


P/A has an ONLINE SUPPORT WEBSITE to order parts etc, and may be a useful resource as well. Do some fishing, and you may find what you're looking for.

I will too, and post any findings.

Make sure your head unit is off.

Reset the amplifier using the manufacturers specified method. Usually this is just power down briefly and then back up. I usually pull the amp fuse and make sure all LED's on the amp go out. Wait 10 seconds, and then put the fuse back in.

If the LED comes back on when you reconnect power, without the HU being on, you've got a bad amp.

If the LED does not come back on after reset, then check for short circuits on the speaker leads. Still leaving everything off, from the amp terminals, remove both wires to a specific speaker and check for shorts.

SOURCE: THE PROTECTION LIGHT COMES ON

make sure your ground is drilled threw thick metal and the paint is scraped off and make sure that all the wires connecting the amp are 4 gauge or higher and if that doesn't do the trick get a better amp that can throw more power

SOURCE: Protection light is on my REM 4300 planet audio

That means that 2 wires must have touched and the protection light came on to prevent further damage.. There is usually a reset button somewhere on the amp and pressing it should reset that light

I have just bought a planet audio ap1500d and when i hooked it up the protection light turns on not the power


disconnect any woofers and retry the ignition sequence (if still in protection get yourself a digital multimeter and check to make sure you have @ least 12volts of power (if under 10 volts the amp will go in protection from under voltage)and good ground as well as remote if you do have all these things return the amp where you bought it or have it checked out) if the amp works you have a blown woofer

What does the red and green light mean ???


red and green light? there is most likely a protection and a power light. The red I assume would either be a protection light or a clipping light signal. Does the amp kick off then these lights kick on red then to green?

More than likely, your speakers are wired up in such a manner that they are creating more resistance than what the amp can handle. That's usually what puts amps into protect mode.

Car speakers should be 8ohm's resistance, but if you're bridging and running a dual voice-coil sub or two subs in series... you could have inadvertedly wired it up so the amp is seeing 4 or 16 ohms of resistance? (depending on which way you went)

Try removing the speaker wire completely, then turn the amp/car on and see if it still goes into protect.

My amp protection light keeps coming on


If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, read through the following page.

This amp is similar to many of the planet audio class D amplifiers. These amplifiers have quite a few problems. If the amplifier has failed, it needs to be serviced by someone who is familiar with the amplifier.

Do not repeatedly replace the fuses. It will lead to more damage and a more expensive repair.
