Negative Tinsel Lead touched the Positive!!!

[JKD 10+ year member]

Hey guys, this past friday, we installed a setup in my girlfriends car. Kinda got in a rush and I'm paying for it right now //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

I have a 12" Soundstream SPL Mule from the late 1990's. The subwoofer is actually really nice, in my opinion. I bought it pretty cheap because one of the tinsel leads (negative) had been soldered up.

Well, had it hooked to a Soundstream Reference 500 amp (old school) and it pushed it pretty good. Good enough, to rebreak the tinsel lead. Well, we resoldered it again and it worked great. However, over a few minutes it broke again. This time wasn't so lucky. The negative tinsel lead slapped into the positive. In turn, cooking my somewhat "rare" amp. It's on it's way to be repaired now, unfortunately.

My question is: Did this little episode damage the sub? I haven't tested it out because the lead is still broken. There is a local shop that said they would run both new tinsel leads for $30. I'm going to do this providing the sub isn't damaged from this.

Anyone else have this happen before? If so, what was the outcome? I should probably test it out before dumping $30 into something that may yield disappointing results.

Thanks in advance guys.

Moral of the story: Triple check to make sure your fuses are correct and not too large and don't ghetto stuff up by rushing things and not taking your time to not check everything twice. Oh, and run new leads - don't solder them. $30 bucks is cheap insurance to not damage your amp and/or other stuff.

and make sure you put enough solder on that bish.

G/L, mayn.

With my limited knowledge, I would still

guess that the short between the two leads

prevented any real signal from reaching the

voice coil. I think your sub is fine.

Thanks fellas. I'll keep ya'll posted.

I too think the sub is fine.

just the wires touching I dont see why the amp wouldnt go into protect instead of frying

i dont think the older sound stream has it. i might be wrong tho

its an olllllllld amp... i doubt it has protection circuitry at all, and if it does its prolly not anywhere near as advanced as todays amps

Don't know about all that guys. All I know is one of the resistors popped next to a capacitor.

I didn't look at the correct amp fusing soundstream recommends and a previous owner of the amp had a MUCH too large 60A fuse in there. Not sure if that is why this happened or not though. Lesson learned. Going to fix everything up before putting everything back in.

the sub should be ok, just make sure that solder bond is really secure, otherwise you may have to get a new sub from re soldering all the time. hope the next time around goes better for you man!

Thanks boomzilla! I'm not going to try to resolder it. Just gonna let the shop run whole new leads. They know alot more about it than me. Been there for 20-30 years or so.

I could probably try to get it to hold, but I'm not going to take that chance. I strictly use "old school" amps and I'd hate to have another 200 dollar mistake if it decides to break again.

Anyways, thanks guys !
