Amp help *NOW WITH BIG UPDATE*, The LED went red Options

[aslearvert]

Ok, I have a power acoustik 980 watt plasma sphere amp (part # TS980-2... I think). Its hooked up to 2 kicker comp subs. Today I was listening to it at medium volume (not even close to the loudest I've ever had it) and the LED went from green to red. I'm pretty sure the subs didnt blow. There was no loud noise, It just stopped working. The amp wasnt hot at all so it didnt overheat. Is there some way to reset it or something. I've turned my car off and let it sit. I disconnected the power cable from my battery and the LED is still red which the manual says stands for "protect". I checked the fuses (by eye, not with a meter) and they seemed ok. Can anyone help me out with this? Is there a trick to get it working? What should I do?

Thanks for all your help

check the fuse for the power cable....

Disconnect the sub(s) at the amp and then switch it on. If it then works OK then there's something wrong with the sub/wiring. The protection feature should reset itself once you switch power off (and the amp is cool).

CHECK YOUR GROUND!! a lot of times protect will come on due to a bad ground, make sure its a clear spot and the paint is removed

Thanks, I'll give all those a try when I get home, and report back.

Sounds like the ground

I checked the ground and its working. I checked all the fuses including the one by the battery, and its not blown. I disconnected the speaker wire and the LED was still red. I dont smell any burning or anything so I dont think the amp is blown. My fuse holder was a little burnt though because it looked like the fuse was bouncing around in it for awhile. So I am going to buy a new one and hook it up to see if it makes a difference. Any other suggestions?

-Thanks for all your help everyone.

Its been awhile and I didnt know if anyone was still interested, but I thought I'd post whats goin on with this. We determined that the amp was bad because no matter what we did the amp would not go out of protect mode. I got a new one, its a kenwood KAC-8103D. When we replaced it, the amp worked and did not go into protect mode, but the subs were barely working. We found a test to use online to see if the subs and amp were bad. We hooked up my ipod directly into my amp and ended up getting the sound we were looking for, so this meant the amp and subs were working fine. This left the deck and RCAs to rule out. We pulled the deck out and replaced the RCAs and still barely any sound came out. We heard that the outputs on decks can blow, so thats prolly what happened. I talked with a sony rep (for a VERY long time) and they said they would replace it under warranty. So hopefully it works.

Yeah Sony had a problem a couple years ago with their outputs being bad. My friend had a brand new Sony deck with the motorized faceplate and stuff and we could not figure out for the life of us why we couldn't get the subs to work. We took it back to the place we bought it and they determined it was the outputs. good luck with your endeavor.

Well my subs and speakers all sound better than they ever have this morning after working on my car until 2:00 in the morning. I finally got my refurbished sony deck back from sony, and I put it in and still there was very little sound, so I thought it might just be something with sony decks... So I bought a kenwood deck to test it... turns out it wasnt sony. I always had static in my speakers, and weird noises. So I thought I had seen something in the forums about a factory amp. Sure enough the guys at best buy just left it hooked up to the deck. Well after doing a little bit of thinking, this may have been the problem. The speakers were getting a lot of power, and were really loud, while the subs were still very quiet. Anyway moral of the story... IF YOU HAVE A FACTORY AMP AND ARE INSTALLING AN AFTERMARKET STEREO, UNHOOK THE AMP!!.

Oh and also, my old amp and Sony refurbished deck will prolly be up for grabs soon if anyone wants them.

The amp is a 980 watt power acoustik plasma sphere TS980-2 and the deck is a CDX-400... I dont really know how sonys numbering is, but its something like that. I just got the refurbished deck from the Sony factory yesterday with a new wiring harness and all the accesories. I only plugged it in once to test it. I wanna test the amp out before anyone buys it, and make sure everythings ok with it, but if not the deck is still up for grabs.

Its not uncommon for a headunit/reciever to drop a channel. I work at an electronics retailer and deal with these kind of issues a lot.

I had the best question at work the other day, Customer comes in wanting to hook up 2 outdoor speakers. He says he had a reciever but blew it out...So I figured he probably had it for 10-12 years or so because they last so long.. So I had to ask ... What happened to the reciever? verbatim "Well, I ran out of places on the back of the reciever to hook up speakers and I had one extra speaker, so I twisted the positives together and negatives together of two speakers and screwed it in...Any idea why it blew the reciever?"
