Mmm, the smell of smoke.

So I bought a couple Polk C300.2 amps on super discount, they were some floor model amps. Hey, they worked good... well, until they stopped working, that is.

one amp to the front components, one to the sub.

Burned out the fuses one day in my component amp, so I put new ones in... blew them... doh! forgot to unplug the battery.

Unplugged battery, put new fuses in, connected battery... whoa! terminal started smoking! ... and fuses blew. But no, SuperK won't give up just yet!

So... Unplugged the battery, plugged in MORE fuses (I know, this kid won't learn!) then slowly, carefully plugged the terminal back on the battery, not causing a spark... or at least not a big one... fuses still intact, great!

turn on the radio... plug in a cd, music starts playing... only out the sub.

So I turn my head and lower the seat to look at the amps, and I see this happy white smoke pouring out of one of them. Do I turn it off? Naw, I just stand there and stare at it. For minutes. Then I realize my car is going to stink of burned electronics so I disconnect it finally. but when i go to disconnect it, it randomly decided to burn my last two fuses. bastard amp

lol. I've done this once. Very expensive mistake.

sure you didn't put a screw or something threw the power wire? or maybe put it through a part in the fire wall that it would get cut on?

I always suggest a professional install. Because not too many people know what to do when something goes wrong.

I'd take it back where you got it to have it tested. Or replaced under warranty. But if it's an installation problem, they will just throw it back into your face.

but it sounds to me like the component amp's speaker output was shorted - thus overheating the amp to the cooking level. It happens. A speaker wire touching ground, a speaker terminal touching ground. Most amps blow the fuse before a problem occurs. But sometimes the amp is just kaput.

ummm.. not to sound mean or anything, but when a fuse blows you are supposed to fix the problem and then put a new fuse in. Also your logic of slowly putting the terminals back on makes no sense. Next time get a professional to do everything.

Heh Professional install

Maybe he didn't want it to look like mine

Fuses mr1in6? I don't use no stinking fuses. Seriously though I use fuses from the front to rear and between battery bank to battery bank but if you look close no fuses to the 2 1200.1's. If you have a fuse pop in an amp there is likely something really bad happening, that usually another fuse won't fix. Only amps i have fuses in are the ones requiring a fuse to power on. Protection circuitry should kick in if there is a direct short before any fuse will pop. If a fuse pops in an amp the prtection circuit is dead and preety much so is the amp if the fuse pops as they are all located on the input side of the amp, which means anything bad happening at the speakers has already passed through the amps outputs and inputs causing damage on the way.

In the electronics world that is called the Magic Smoke b/c when it leaves the electronic piece seems to no longer work.

I had that same magic smoke come out of a sub about 1 month ago. It no longer worked either

, Upon dismantling the sub a "slinky" came out of the MOTOR assembly.

same thing happened to my bro....... bt he did it worse..... he kept on blowing his 40 amp fuse for his 1000 watt pyle amp...... which was powering a 10 inch kenwood typhoon sub pushin 125 watts...... so the kid decides that hes sick and tired of replacing blown fuses and puts in a 60 amp fure and leaves it....... he moved to ontario and well lived there for 2 days and moved back and just before thunder bay poof the whole cab fills with smoke small flames come out of the amp so here the kid is driving down a windy road rolling down his window turning off the radio and trying to see through the thick smoke and put out the damn fire... some how he manages to and well the amp fried completely butt the sub is ok and still works..... beats me how the sub didnt blow but ya it was a brutal ride home for him...... o and mcdonalds food gets rid of the burnt smell in the vehicle as per my bro

That is b/c McDonals smells worse than anything on the planet to begin with. Live and learn. I hope he learned his lesson.

Why no, I didn't learn my lesson!
You should have seen what I did to my computer!

Billows and billows and billows of schmoke. It burned in my power supply connectors straight on to the motherboard.
Still worked, though.

I wasn't too worried about my Polk to begin with. I double checked the connections before I re-fused the thing, then I placed my second amp in the first one's wiring, to see if it'd blow. It didn't.
It was already cutting out at random times, so I figured it was on it's way out. Still got warranty, so am A-OK on the thing. Thought I'd just hasten it's death. Cruel to die slowly, and a whole lot more fun to kill it fast!

My amp just went yesterday night...

I noticed driving home that it was not working right (could not hear my subs).

I got home and checked my amp (sony Xplod 1200 watt). Sure enough, the protection light was on. Oddly enough, the amp was still on as well (it was still glowing blue).

I checked all wires, and they were all good. triple checked my ground wire as I figured that may be it. Still nothing. Also checked all fuses, they were good.

I turned off the cd deck, then turned it back on. Hey it works!! or does it? nope, after a few seconds, I hear a "POP" from my speakers, and the light on the amp is back on. WTF!?

Turn off cd deck again, turn it back on but keep volume off. This time amp stays on.

I find out that when I turn up the volume, or turn up the subwoofer bass setting, the amp goes into its protection mode.

So best buy has my amp in for repair. Hopefully Sony don't try to pull some BS on me and make me pay for this crap... lol

same thing happened when my bro hooked up his new system and he ended up having a blown sub so it would set the amp in protection mode.... its a rockford p2002 amp so maybe you have a blown speaker or sub which may cause this....
