Are you talking about the diagram on the unit itself? Are you trying to install without the factory harness or are you just wondering what wire are what?

Sounds like there may be a problem with the unit internally. The laser may be out of alignment or very dirty. Have you tried a cleaner disc?

What exact model of amplifier is this?

I would suspect the factory amplifier has failed, or possibly the factory sub is blown. Try unhooking the sub and then power the system.

Depending on what model of P3 you have, you'll need to order re-cone parts. The subwoofer will have to be stripped down to a bare basket and all glue sanded off and surface clean. Shims will be needed to get the coil in place properly around the pole. Clamps may be needed as well until the glue sets. There are many videos online to show you how.

Something is shorted on the output, or there is a leaking or shorted op-amp in the input section.

There is something shorted inside the amp causing it to shut down.

Decent amp, not my favorite line. These models were built a little cheaper and tend to suffer catastrophic failures.

For what?

No problem!!!

Shorted components inside the amp or the speaker it was hooked to could be shorting the voice coil.

If this model is a pre HD model, you must remove the bottom cover and there are 4 fuses inside the amp on the circuit board.

Is it going into thermal protect or short circuit protect?

Are you running the amp bridged mono or in stereo?

Are they in the manufacturer's recommended enclosure size?

Here is a wiring diagram. Second from right is positive and third is ground

It can't be done unless you choose to include some power resistors in your circuit for impedance matching. The problem with that would be some of your power will be lost in the form of heat across the resistors without the benefit of contributing any sound. Also, the amplifier's damping factor will be compromised, so you may notice a loss in sound clarity. It's possible that you might not easily tell with subwoofers, depending on the enclosures they're mounted in, and whether they're isolated in a trunk vs being in the same airspace with you (hatchback, SUV, or pickup truck).

You have shorted outputs that are causing this. The amp will have to be repaired. I can repair it for you.

Yes run it in parallel for a 2 ohm load.
