smoking amp, no blown fuses

[bjanicek]

I know that this amp worked as it was in another vehicle before. I hooked everything up to make sure it still worked after it was ran at low voltage after an accident. About 5 to 10 seconds of power being supplied I heard a small pop and some smoke rolled out. I immediately disconnect power but no fuse blew and the lights were still on. Also, there was no audio running to the amp. Not sure what could have happened and wondering if it could be serviced, no warranty, amp is a few years old.

Pop.. probably something to do with the onboard capacitors.

IF it's korean or chinese made, there are many service centers to choose from.

Even your local audio shops may have their own technicians there to service amplifiers.

In our city, our local shops will service any amplifier that shares the same Board designs of products they sell.

I also had my subs connected at 1 ohm and a pre-amp connected. The amp is stable at 1 ohm and the subs are dual 4 ohm voice coils. I was going to test everything but as soon as I hooked the battery up this happened. Could any of that play a factor?

What amp is this?

Pretty much. They are good for about 2- 3 years max.

Well that's unfortunate. It is probably about 3 years old. worked great originally but I got a new car after my accident and it's been sitting for months now.

You didn't accidentally hook up the power and ground backwards did you?

It has happened to me before.----- magic smoke----blown caps

 

[bjanicek]

I had two caps in series before the amp and the wires to the amp from the second cap were backwards but I didn't have the trigger wire installed. Disconnected power, switched wires and installed the remote wire. Connected to battery and then it smoked.

You cant wire caps in series. Then you would be seeing higher input voltage like 16+ volts. That can fry an amp.

Sorry, I had them wired in parallel. Got myself confused, they have digital readout and were setting nicely at 12.3V

wiring the power and ground backwards even without the remote wire hooked up might still smoke it.

I had the ignition off- so remote wire had no +12v signal,,,, still smoked

I have an inline fuse that blew when they were wired backwards. After I switched everything, no fuse blew, turned on like normal and smoked after a few seconds. I cracked it open and there is no visual damage but that doesn't mean something still isn't fried. I don't want to cause more damage and have to buy a new amp if it's just some internals that could be replaced.

To direct current a capacitor is seen as an open circuit. Capacitors only come into play when the current level changes. They charge as the current is turned on, then if for any reason the current level drops the capacitor attempts to equalize it back to the level it was. But capacitors get really fun with AC!
