Ok If the power wire as well as the remote wiring was checked then you know the problem has to lie within the amp?? Yes it does. Do you know how to check b+ lines with a vom?? as well as use a schematic to trace one curcuit to another?? If not its best in my mind to have a pro look at the amp but if you really wanna try to see if theres something burnt in side by all means open it up look around and if you dont see anything out of normal such as burnt things crispy parts or fried wire then its time to unistall the amp and take it to your local repair depot. Now your local repair person may or may not be a sspecialist in auto amps?? If not My advice would be to ship your unit directly to the manufacturer for repairs. First thing you wanna do is look in the owners manual under troubleshooting . it will tell you where to call and if a RMA is needed(RMA means Return Materials authorization).Or contact the company at 1-425-788-0932 or online at [email protected] Good Luck

I have a PYLE Amp. Model No. PLA-2380. I had it installed into my car it was working great! And then one day it just stopped turning on. It is getting power, the Ground is still good, And my remote wire...

You want to verify your wiring first. Use a volt meter to make sure the power and ground are good. You can jump the + to the Remote to bypass the head unit(after unhooking the remote wire). If at any point you had your speakers short out or wires hit together it will have smoked your power supply and damaged it internally. If you end up verifying the power and remote are working right and there is still no amp turn on, measure the fuse for resistance. Should be 0 ohms. If the fuse is good, the power/remote are good, then the amp is internally damaged. Any number of things could be wrong. Good luck

Everytime I cut it on. It cuts back off like there is something wrong with it

If you turn it on and it clicks right back off you may have a short. Make sure the wire panel does not have any straggler wires going from one connector to another. Also you may have a very weak fuse. Check the fuses in your amp and at the battery terminal. Make sure the power, ground and remote wires are solidly connected. Make sure that ground is tight. Is the deck shutting off at the same time your amplifier does? The remote wire off the deck powers that amp so if the deck is also cutting out the problem may be the deck and not the amp. If this is the case then run through the steps I listed above but with the deck as well.

I have a sony explod stereo and it works fine. Ecept that every once and awhile it shorts out and stops playing for a couple seconds. When this happens all of the stations i had saved and the clock are all...

could be power, could be ground, do you have a factory amplifier aswell as an aftermarket one in your vehicle.. If so if you have the 3 remote wires spliced together to kick on your factory amp you can have problems with this. Basically having more than 1 amp wired in series together can do this... there are many factors to this but first check your ground on the headunit and make sure it's makin a good chasis ground..

!!!red protect light is on!!!

Hello beaugarcia26,

Unless the amp itself is defective, there's a short or ground somewhere.

First disconnect the speaker wires and RCA (or high level) inputs, leaving just ground, remote turn-on and power leads connected. Then see if the amp powers up normally. If it doesn't check the ground with a multimeter and make sure it is good. If the amp powers up normally, check the speaker, speaker wires and inputs for shorts or grounds.

Hope this helps.

If you have a voltmeter, check that you have 12V at the power connections and also that you have 12V at the remote turn on terminal. If this is all OK, be sure that there is no short in the sub box cresated by something loose. If this is a sub that you take in and out with quick connectors (like the kind you push down and then insert the wire into the hole) be sure that there isnt a strand or two of stray wire shorting the terminals on the outside. If all that checks out, you most likely have a bad amp.

Sony Xplod amp no longer working

First i'm sure you have checked all fuses. Second you need to test if you have voltage coming out of the remote wire. If not and no fuses are blown then something shorted out internally and you need to run 12 volts to the remote wire on the amp. You can do this by using a switch and running a wire to it from your fuse box, or you can find which side of your fuse box is switchable, which means that when you turn your key to the on or accessories position that power will run to the remote then. Make sure you don't use the constant power side or your amp will remain on all the time. Now, if everything is fine and you have power on the remote wire coming from the head unit going to the amp and no fuses on the amp are blown then something is shorted inside the amp. Then I suggest you take it back where you bouhgt it if you bouhgt it at a store and your able to return it. Ifr this is not an option then I own my own amp repair business and if interested I can repair it for you cheaply. I am the cheapest you will find anywhere. Most of my customers are from this site. If interested send me a private message by clicking on my name. Hope this helps you out, let me know please so I can continue to assist you if you still need more help. Good luck

My 2000 watt nitro amp just stopped working need help

Think about anything out of the ordinary that may have happened the day (or day before) it quit.
  • Was work done to your system?
  • Did someone mess with your system?
  • Smell anything odd?
  • Especially loud?
  • Did it quit mid-song or did it work yesterday and not today?
Assuming nothing special, here are some diagnostics you can perform. At the very least, they will help tell you what the problem isn't, First....

Eliminate power supply problems.

Use a meter to make sure you have power to your amps +12v terminal. A meter is preferred over a test light to confirm a full +12 volts.

Make sure the ground terminal is grounded. A meter with a continuity test option is best for this.

If either of these fail, trace the wires to find the fault. Large amps like yours normally have dedicated power cables. These cables usually have an additional in line fuse close to the battery. Check it.

If they pass, double check the amp fuse.
Pull the wire (usually blue) from the 'remote' terminal on the amp.
Then try jumping the +12v line to the remote terminal.

If it still doesn't power up, check for signal shorts.
Turn the gains down low.
Pull the input lines and try the +12v to remote jump again.

Next pull the speaker wires.
Your amp should now have only two wires and a jumper attached to it. Try the same jump.

If it still fails, the problem is in the amp itself and (I'm sorry to say) leaning toward the serious.

Hope this helped

Start removing wires from the amp, one by one (except for the +12V, Ground, and remote) until the amp seems to work fine. Usually, this type of issue is due to a speaker wire shorting to something it shouldn't be touching. Check the "non-amp" end of all the wiring to make sure they are solid and correct.
