My Precision Power PCX2125 amp is just making a clicking sound win on what is wrong


Not a car amplifier man.

Do know the clicking sound is a circuit breaker. You are hearing it set, then click off.

Something is overloading the amp, or something HAS overloaded the amp.
Like somebody hooked the crossover wrong.

(Hmmm, lemme see...........Subs need 4 OHM's, and tweeter/mid-range needs 2 OHM's, and I need to bridge it how?)

Has overloaded may mean board level component repair.
You're going to need a solder jockey for that.

(However I wouldn't be surprised, if it's easy to replace Electrolytic Capacitors inside. Just need a little soldering expertise.

Yes, this is for desktop computer mobo's, but can apply to any electronic item that uses them,

I have a PCX-5F POWER ACOUSTIK 5-Farad Digital Capacitor and after i turn the car off it stays on and sometimes when the keys not even in the ignition the cap stay on. why is it doing that?


It is a capacitor. Please read up on how capacitors work and it will explain itself.

The capacitor is holding a charge, just like it was designed to do.

I HAVE A PPI PCX 2200 THAT IS NOT GETTING ANY POWER AT ALL I CHECKED ALL FUSES STILL NO POWER


1.verify connections...Make sure your ground wire is grounded to a location on the body where you will sand the paint away to make good metal to metal contact. 2.with a volt meter check for battery voltage on the red wire of the amp as close to the amp as possible.verify that your remote or trigger wire from the radio (blue wire) id connected to the remote terminal of the amp.. turn on key switch, turn on radio and see if amp powers up. if no then verify 12 vdc at the remote terminal of amp, very 12vdc at red power wire. verify ground. If all this is good i would suspect you have a faulty amp.

I have a PPI PCX-2400 and want to power two TREO subs that handle 2500 watts apiece. What is the best way to ire the PPI to these subs so that I get as much power from the amp to the subs without causing...


That would depend on the impedance (resistance) of the subs. Your best bet would be to use the full power of the amp to one channel (i.e. bridged) instead of to two separate channels (i.e. stereo). Two 4 ohm subs wired in parallel would present a 2 ohm load to the amp, which should allow you to get all 1600w out of it.

This explains series vs parallel quite well:

Need to know how to bridge the channels on the amp is it left pos and right neg or opposite


If you look at the speaker hookup it will say bridged and have a line going to the two that you should use....If it doesnt then it might be an amp that you cant bridge

Subs and amp sat in my garage for a year. I just


check your subs by connecting them straight from the stereo. If they work then there is an issue with the signal comming from the stereo through the rca cables to your amp, check those. Try another amp if you can with those rca's or test the amp with a friends car, either way try to rule out everything until it points to the problem.

My ppi 2200 power light flash's on and off


yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

PPI AMPLIFIER NO SOUND PSX-280


make sure the remote wire from the deck is in the amp but move your ground wire to a new solid metal location you may have to scrape the paint surface where the ground is going to go but it will stop protect mode and run properly (make sure to bolt it down by its self no other wires just the ground from amp) also make sure the ground wire is bigger than the power wire
hope this helped

Cant figure out where to connect the remote wire to


The Remote Wire Connects to the Blue Wire From the Stereo If you have an Aftermarket Stereo. This will control the Amps Power with the Ignition Start and Accessory Positions.

Problem in ppi pcx-2400


Check the amplifiers fuses. Some amps have speaker fuses that leave the LED on if blown. Check for continuity on the voice coils of both subs. Check for 12 volts on the remote turn on line from your receiver. If all of the above are good, the amp is probably toast.
