SOURCE: in thermal mode

if i understand correctly its possible that the amp shorted out during the bump...check all connections and fuses, if all is fine then the amp needs repaired.....watch out for those bumps next time.

SOURCE: No Power :( NEED HELP

Check the connection with the subs. See if all wires are connected or check for any break in the wire. Also make sure that the RCA's are connected to the subwoofer output at the back of your deck. Also check setting on your AMP.

SOURCE: lit up like a christmas tree

If they're green, that's normal. IF they turn amber, there's a problem. The lights don't indicate whether the power supply is working or not. If you get no sound, the power supply in the amp may have failed.

Cannot get pyle driver 413 bridgable mosfet1000 watt amp to work with 800 watt subwoofer . followed instructions all the lights are lit but no sound need help


just wondering how you connected the amp . you should do the following steps
1 battery cable with right size fuse at battery
2 remote wire from radio
3 rca cable from audio out from radio
4 ground the amp to a good clean piece of metal

then make connection on the amp
1 battery or power cable to the 12volt connector on the amp
2 remote wire to b+ or rem on the amp
3 rca cabel should be pluged in the channels are using cause you tell me that the amp is 4 channel
from the model numbers
4 clean and scrape off paint on the metal surface you are going to install the ground cable from the amp . make sure your ground is no more than 12 inch max. and is the same gauge as the power cable
5 . run your speaker wires to the amp and make sure your ohm load for the subwoofer is 2 ohms or 4 ohms to make the amp work proper .

if need help on anything email me @ caraduioquestion@gmail.com

No sound from speakers, but there is power to amp


make sure the power wire and the remote wire have voltage. at least 12 volts. make sure the ground wire is good and has a good solid ground. after that make sure the rca cables are getting signal from the radio. if you have a small speaker or tweeter you can touch the wires from the speaker to the rca cables and it should play music very quietly. meter the subs and make sure theyre ok and not shorted or bad. if all that checks out good.... the amp is probably bad. start with all the simple stuff and work youre way up. if the amp has good power and signal and good speakers then the only thing thats left is the amp. good luck

Amp Power Protection


sounds like the amp gain is too high, grounded incorrectly, or the amp is bad. the ground wire should be no more than 2 feet long.

Powers isnt turning on but everythings hooked up?


Check the fuses. If the fuse is bad the amp's power supply is burnt. If the red light stays red and never goes green then your amp is in protect mode and the output section is burnt.To test for rem. problem just use a jumper wire (paper clip... or whatever)to jump from +12v power to rem. If rem. wire has no voltage when your radio is turned on that will make your amp come on. then look for the fuse in the rem. line. Good luck !

RCA Pre-Out Making Producing a Mumming and a Popping Sound.


the speakers hook to speaker wires not to any thing else no power no negative poles do you have a remote shut off switch connected to amp this would be important to cut off amp

when cut off amp if you still here the humming this can be an indicator of low power being produced by alternator alternators produce 14 anything below 12 would mean replacement of alternator

if alternator fine then you need to find new ground for amp and make sure you have a good ground for sterio this can be checked with a test light
to check a ground all you do is hook gator clip to power then touch test light end to ground on radio end light comes on got a good ground (make sure not to touch any other sterio wires just the ground wire while connected to power to check grounds)
if pulsing in test light on the ground means you have a bad ground
just disconnect move to better ground

check the amp ground the same way as decribed above

My car amp works produces distorded noise . As I plug in the rca cables i noticed that if just the tip of the connector touches i get a good sound but if i insert the whole connector it becomes distorded...


You have a grounding issue.

The RCA inputs of the amp are many times NOT tied to chassis ( the chassis of the car ) ground.

Same goes for the RCA outputs of your head unit.

The speaker outputs of your amp SHOULD NOT EVER be tied to chassis ground.

  • make sure that no speaker wire from the amplifier is touching or attached to ground.
  • Make sure that your amplifier ground (GND )( of the 3 power inputs.....GND, +12V, Rem) is securely mounted to a bare metal spot on the frame. Best practice is to have the amp GND, and the head unit GND at the exact same physical point.
  • Make sure that your RCA cable shield ( not the center tip, but the part around it ) is not touching the chassis.
  • Make sure that you have not nicked the wire while installing it and are accidentally getting a connection to the frame of the car.
  • Make sure that the head unit is grounded properly.
  • IF for some reason you have an equalizer between the head unit and the amplifier, make sure it has its own switching power supply INSIDE the EQ.
Bad grounds are a pain to troubleshoot......best of luck....Rob
