I've got an old Kenwood stereo. When I play it, there is usually a high pitched loud sound, followed by smelly speakers. This was temperarily fixed when I re-plugged everything (speaker wire, cables, etc), but about a month later the sound came back. Again, I unplugged everything, and when inspecting the wires, I noticed that a spot on the speaker wire was burnt black.

What is the problem? The poweramp, the speakers, or something else? I'm getting quite annoyed because right now, I'm using a terrible small stereo with NO PHONO OUTPUT (no turntable).

Buy a new stereo with a phono output!

I'd have to buy new speakers, cassette decks, CD decks, everything. I'd rather just replace one part. But I'm willing to buy a one piece stereo if it's cheap. Can you suggest something?

A grounding problem perhaps ?
Something must be burning up or heating up ?

A new stereo is my suggestion as well before you find yourself in a blaze.

Any friends you can borrow a part of to see if the problem is actually the amp or the speakers ?

Where on the wire?

My advice is start with new speaker wire, and make sure you have no dust or detritus shorting out your stereo.

It's randomly in the middle of the wire on the plastic, there's also a few smaller spots on the wire as well.

I have a pioneer system myself, nuance speakers. As good as anything else in the $5000 range I suppose.

Many claim harmon kardon is a great system. Fuck, to me and my broken metal ears myspace sounds fine over a relatively cheap computer system, so pick any brand name I guess as they are probably all about the same. Wink

This may be a gay question, but + to + and - to - correct ?
No accidental wire crossings or mislabelled wires ?

I would replace the speaker wires first, but monitor them while in use
-the speaker wire may be too light of a gauge for the power load...too high of a resistance
-the speaker wire may have been kinked in those places that are burning, therefore some of the strands maybe broken and creating higher resistance
-if it is only one speaker that is the problem, you can compare the output of both speakers with a multimeter to see if the amp is acting up on one channel
-if it was the amp or the speakers that were the problem, chances are the places where the speaker wire would be burning would be the connections at the amp or the speakers because these would be the places of highest resistance (high resistance gives off power in the form of heat)

The above post helped very much. There is one small detail that I didn't think was important. The wire input in the back of one of the speakers is slightly yanked out.

And the poweramp is 125 watts power, perhaps I need heavier speaker wire.
