  cable burning
After you've stopped laughing, maybe somebody has an answer for this. I have Transparent speaker cables. At the amp end of this cable there is a black plastic cover. This is where the cable is seperated into two connecting ends....about 5" or so. I recently bought new amps and the posts are at each end of the amp. The cables didn't have enuff spread to reach. My local audio dealer said he could have the cables sent to Transparent and for a cost they would extend the ends to what ever I needed. Where I work, we make some cables for barcode reading guns. Thinking I could save a few $ I brought mine in thinking we could take those plastic boxes off and recover the cables with some sheathing and it would give me the extra length I need to reach the posts. We had a little trouble with a resister that was glued into that plastic box but we were able to make it work. I had just barely enuff length to make the connection. I have Mag 3.7 speakers and they are fairly new....about 120 hours on them now. So, I havn't been playing anything to loudly, till the other night. I decided to crank it up some. All was well until, here it comes....I see smoke comming up from behind one of the amps. A thin line like from a cigarette left burning in an ashtray. At the same time I smelled it. I hit the off button on the CD and dived to the off buttons on the amps. Upon further review I could see that the speaker cable right where we had covered that resister was melting. After waiting for it to cool off, I covered it with some electrical tape and turned it back on just to see if it would still play. No problems Sounds fine. My intention now is to do what I should've done and send them in to be fixed professionally. Seeing as how I have very little knowledge of all things electrical, anybody want to try and explain what happened?

Thanks for all the suggestions. I'm sorry but I can't be any help as far as the resistor value. Just from a common sense approach I think Almarg may have hit it with the idea that it was covered so tightly may have trapped the heat in. I never imagined that that much heat could be sent thru a speaker cable. In the original form that resistor is located inside that plastic junction box cover where the cables spread apart. I may have just suffocated it. Since this happened I've got about 12 more hours played and everything sounds fine. I will be taking them to be repaired properly very soon and I will ask them why this happened and pass it on then.

Well, I've already made a mistake by mess'n with the little plastic cover. I have no intention of doing the same with the big box in the middle. Again, when these go in to be repaired properly I'll question what goes on in those enclosures. Something tells me you won't need an answer cause you'll have it figured out before then.
