Ok, I did a really dumb thing - a really stupid thing - I think I broke Ohm's Law.

I bought a Pioneer amplifier (GM-5000T) on E-Bay, which had a broken RCA jack. No big thing - I removed the circuit board, soldered on some new jacks, and voila - problem solved. Unfortunately, the left channel output didn't provide any sound to my speaker, but that's unrelated to the repair, and I have little recourse to say it's a problem - the amp was sold 'as is', and for $25, you get what you pay for.

Now, here's where the stupidity comes in. I hooked up the stock speakers (in my 1989 Saab 900S, which I'm sure doesn't have the best stock speakers to begin with) to the functional right channel output, essentially placing two 4 ohm speakers in parallel.

(Co-incidentally, I read the manual after the fact, and it says this is a 'big no-no', as it can blow the amp, etc. etc.)

So, I was driving along for about 15 minutes, and then I heard a small 'pop', and all my music was gone. I checked the amp, and the power light blinks on and off, and only a small ticking is heard (in unison with the blinks) from any speaker attached.

(Yes, I know... "Bravo!" )

I've removed every other connection except the power, ground and trigger lead from the head unit, and still, the light blinks. (I have since verified that the RCA outputs from the head unit still put out sound, so thankfully, it was not one of the casualties of my misfortune.)

My question is: can the amp be 'reset' in some way, or is it likely totally pooched?

Does anyone have any ideas? (On another note, if its a 'quick fix', is there any way to troubleshoot the lack of sound from the left channel output?)

Thanks, very much, in advace!

Anyone? I see a bunch of people have read my post, but I didn't even get a nibble yet.

(Perhaps the experts haven't read it yet...)

nope no experts here
disconect power and reconnect to see if it resets itself it should have some sort of protection circuit against short a circuit or thermal issue
