Hooked the damn thing up power my subs wonderfully for that evening, and all day today, got in this evening and nothing, checked the amp and red light, ok, fine, checked the manual, says the light protects...

probably something corssed in your speaker wiring. be sure that you did not exceed the ohmage capabilities of the amp, and that no speaker wires are crossed, or shorting out on the frame. if you have too many speakers hooked up, that can reduce the ohmage, and your not supposed to go below 2 ohms -per channel, or 4 ohms bridged mono.

Okay i have a mtx 300.2 car amplifier. ive had it for a while and all of a sudden it stops working.... i take a look at it and see that the red power light is really dim and not as bright as it usually is....

Sounds like your power wire or your ground wire are either not geting a good conection or they are to small to cary the amperige it takes alot of amperige to do the work.

Hi there just picked up a jbl bp 1200 for good price although just wired it up and turned the key to find the red light come on few seconds then solid green and no sound...checked ground,remote wire rca...

Most amps do a "power up" where all the lights can come on, then settle into "green light" or some sort of "ready status" light comes on. The red or yellow lights can indicate "protection mode" (a bad amp) and green is the universal signal for okay. - So try this - Double check your connections and the amp. Pay close attention to the settings on the amp before you declare it not working. I have had many amps (especially newer ones) cause problems from a simple switch that was in the wrong position. Be sure to use good power and audio cables matched to your amps capabilities with good strong grounds on a clean non-painted metal surface. If all is in order from there start checking your signal from the deck to the amp. You can also check manufactures website for the manual, (if you didn't get one) looking at it may give a clue about proper switch configurations and hook-ups. Let me know if you need additional info concerning these idea's.

Red light comes on but amp still tries to kick.

Try removing the caps out of the system. It sounds like they have gone out. What is happening is the caps start storing up the power like they are supposed to do but then they are being discharged as soon as they are full. Bypass the caps and that should correct your problem.

If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. I'll assume that you've checked the amplifier's on-board fuses.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

Let me know if you have any other questions.

Red light on my amp?

Does the amp power up normally if you disconnect the speaker wires from the speaker terminals of the amp?

It's never a good thing to blindly short across a power source.

Okay i have a problem hifonics brutus 1500 mono d class amp

well your amplifier is obviously going into protect mode,(i used to have this amp and it is awesome) anyway i would go through just to be sure and check all the power connections with a test light, remote wire, positive, and ground. and check the fuse to see if it is still good. you can buy a test light at wal-mart and any automotive store. if you stil have a problem then i would check to see if your running below 1 ohm on this amp. that would cause it to go into protect mode. if all this fails i would just go buy a new one.
