Amp runs but then will just turn off and red light comes on

My lightning audio amp will run fine for a few minutes but then just shut off and the green light will turn off and red one goes on. If i take out the fuse and put it back in it will start working for a minutes again then turn off. Sometimes it will work for a while but in the end it always ends up turning off. Any ideas?

Re: Amp runs but then will just turn off and red light...

You need to get a fan for it because it does not come wit one and when you get the fan you have to hook it up from the inside by taking the torture tested/bolt sign off and look for a small white pug to attach it to

check ground cable, check fuse on amp, and check the fuse under the hood, on the positive cable should be about 12' from the battery, if all is well and theres no light, check the blue wire coming from your deck use a tester,if bad you can run one of your fuse box ,place a 12volt switch and hook it to the amp you should be good to go

Amplifier keeps running overcurrent

sounds to me like you are overheating the amp, try down tuning the peak level of the amp, and also if there is anything around the amp clear it away, check if the fan is turning on, you may need to replace it,

Jh202 amp works for a few minutes stops for a few minutes any ideas

Sounds like the amp is going into Protection Mode. Does yours have green LED light then RED LED on it? The green is power and the red is Protection. You will need to either change the OHMS wiring or Put A Fan on it to Keep it Cool Inside.

Amp won't turn on

disconnect audio inputs and outputs and see if one of those are causing it , if it still does it with all audio inputs and outputs disconnected then there is a problem with the power amp

Amp problem

Are you sure that the terminal isn't shorted to the case of the amp?

If it's not, the amp probably has a shorted output transistor.

If you want to repair it yourself, read through the following page. It explains the basics. Let me know if you have any questions.

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.

Red light

It sounds like the output transistors have failed. Disconnect everything from the amp except for the B+, ground and remote and turn the amp on. If it goes into protect, the amp is in need of repair. If you want to repair it yourself, email power acoustic for the schematic.

Overhaul light (red) stays on!

This is not a ovehaul light. It is called the protect indicator. It kicks in when the amp detects a fault on it's output. Disconnect the speaker / sub. Power up the amp and see if the light goes out. If it does you Sub is toast and needs to be replaced. If it stays on then the amp is done.
