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.

2500 power acoustic amp green light no sound to subs

There could be a few potential reasons why you are not getting any sound from your subs even though the green light on your Power Acoustic amp is on. Here are a few things you can check:

Check your wiring: Make sure that all of your wiring connections are secure and that there are no loose or frayed wires. Check that you have connected the amp to the correct terminals on the subs and that the speaker wires are properly connected to the amp.
Check your settings: Check the gain and crossover settings on the amp to make sure they are properly set. Ensure that the crossover is set to the correct frequency for your subs and that the gain is not turned down too low.
Check your power source: Check your battery and alternator to make sure they are providing enough power to the amp. If they are not, you may need to upgrade your electrical system or add a capacitor to your system.
Check for a blown fuse: Check the fuse on the amp to make sure it has not blown. If it has, replace it with a fuse of the same amperage.

If none of these steps resolve the issue, you may need to take your amp to a professional for repair or replacement.

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:

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.

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.

Amp has Red LED light on.

Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

2010 Toyota Camry LE Aux/CD not working When I first got the car, hitting the Aux/cd button did absolutely nothing. Used some contact cleaner to see if possibly the button had debris or was sticking but it did nothing. I inserted a cd and it spit it back out after trying to read it and will no longer accept any cd. Weird thing is now when I hit the button, it will go to CD and will constantly try to read a cd that isn't there. Though it will never show AUX when I hit the button. Tried playing through the aux cord but don't believe it will work unless I can actually get it into Aux mode via using the button. Is this something fixable or is replacing the radio the way to go?
