Default two amps with one spark... wtf happened?

Hey, i have two amps hooked up , each with their own power and ground, etc. I un hooked my amp today to put a new sub in, which I didn't have to do and i wish I didnt. But I was moving wires around, and with the ground cable attached to the amp, I accidentally touched the power wire directly to its terminal.

It sparked and popped. Then when I tried to play music, only my back two speakers are working.(I have a amp hooked to sub, doesn't work. Other amp is hooked up to the two front speakers, doesn't work.) Everything was fine before.
I checked fuses and they look good, so I'm thinkin either the guts of the amp are now blown, or the remote turn on wire got fried.

Neither amps power indicator comes on.
Can someone help meh pleeeease lol.
Really. its making me mad
Thanks

Have you checked all the fuses? Some amps have multiple fuses.

If all the fuses are good, you might have to open up the amp (disconnect everything first) to see if there are any internal fuses or signs of burnt circuit board or components.

There's a good possibility that when you shorted the power to the amp it fried some internal circuitry that will take an experienced electronics guru to diagnose & repair.

Hopefully it wasn't an expensive amp so you can just replace it... if it was a high dollar amp, it might be worth getting it repaired though.

Yea i checked the fuses on both amps and their in line fuses and the cd player and they all looked good. I have never taken a amp apart before , but if that's the only thing I have left to do then i can try. It's not that expensive for a new one but I wanna make this one work :/

You wouldn't have damaged the amp. The short occurred outside the amp before any of it's components. It should have blown the fuse on your amp's power wire where it is hooked up to the battery. However, if you have a self reclosing circuit breaker on it instead, it would open and then reset shortly thereafter.

Sounds like some sort of protection in the equipment that reset after some time . Slow blow ckt or something , not sure . Check your manual or tech sheet and look at the schematic to see if there is anything like that in the device to protect from overload / high current .

That's what my dad said, that it might have overload. I just don't see why it would mess with the other amp. But everything seems to be working now. I think the amp might have something loose inside thep sub amp, cuz I had a wreck with it installed a while back. But never had problems til I touched wires. Anyway maybe somethins loose is why it had been erratic

I would also look at the paperwork and see if it has any special types of overload protection circuitry .
Product type and brand name and we can do an internet search on it as well .

Also if ( hopefully not ) it happens again , try and disconnect the unit and leave it disconnected for about 1 hour ( your choice ) . See if that ever resets it as well . Glad to hear its ok . Kind of like surge supression protection .

Shorting the power wires outside the amps will have absolutely no effect on the internal workings of the amp. The short and excessive current occurred outside the amp and would have no effect on anything after it in the circuit.

If your amps are acting up, then either they are defective/broken, or your electrical connections are intermittent.

I know. It doesn't matter. The short occurred outside the amp. The inside of the amp is uneffected by that.

Without the product type and brand , and knowing how the unit works , there is no way toknow what happened and get to an exact cause of it .
