I have four subs that the speaker leads burned through. What would cause this? Same amp ran all subs. They died at same time. Would amp putting out DC do this? Coils are fine. I am stumped.

Sounds like it has to be too much power if you burned them.

maybe the leads touched each other and shorted or somehow too much resistance occured in your leads.

Do you mean a direct short?

I think that would be tough to do, maybe I'm just not looking at it right though.

it's due to too much current.

If they shorted, lol, then you have modified the design and warranty is void.

If there was too much resistance... then there would be less current so it would be improbable.

I've set a sub on fire before so i know what you are referring to, same principle.

Excessive current to cause this is usually caused from severe clipping.... so i'd suggest you retube your amp via o-scope.

too much power and a clipped signal most likely.

kudos to quality control tho. very hard to find products that fail simultaneously when abused.

lol just throwing up ideas here after a long day at work, gimme a break here! . and now that i re-read his post and noticed all 4 of his speakers went...well....ya.

Lol. All good, just had me really thinking there!

Ok. Strange but OK. Amp (Sundown SAE 1000D)

volume was @30 out of 62 or so. Zero bass boost. Song playing WAS a ridiculous rap song. by ridiculous I mean LOTS of lows. Amp blew all 3 fuses. When subs come back will retune amp.

Have been beating brain to figure this out. Could loss of voltage (ie running out of juice from electrical system have helped cause this?) played into this?

Amp blew all 3 fuses.

That should be an indication of something isn't quite right. Properly functioning and operating equipment doesn't blow fuses on its own.

I get that. This was out of the blue. system has been working fine with no issues. Just Boooooom. Then nada.

Check all wiring, make sure you have good connections (ground too), and check/reset the gain with an o-scope if possible.

Will do all of the above. Got an O-scope so will recheck gains as well as all filters.

Thanks guys!!!

what subs?

E8

Burnt leads on an E8 ? That is something I've never seen - even when we plugged them in to the wall socket.

Any pics of that ?

gonna ask the stupid question here

Are you positive they burnt and did not break from over excursion, reason I'm asking is you mentioned you were playing a song with lots of lows. Leads could have touched when they broke, popping the fuses. Or I could be low input voltage at the amp.

No pics as of yet. I had them looked at and that was the diagnoses. Sorry guys. I am more stumped than you. I have the subsonic on the amp set at about 30 hertz. It is a crazy thing here.

i was told that an o-scope doesnt prevent clipping

An O-scope never prevents clipping. The only thing that prevents clipping is not overdriving the input to any of the stages of amplifier/buffer in your signal chain.

If you have a tough time with this, a simple answer is the volume knob on your deck caauses clipping when you turn it up too high....

And o-scope won't prevent clipping. But it will show you it.

are you talking to your friends at school again about audio???

an O scope is not a add on like a EQ or a cross over... its TOOL like a screw driver..... or who ever told you that.

are you talking to me?

with an o-scope you can find out what volume your deck clips at first, then you set the volume on your deck right below clipping. after that is done you move on to your amp and start to adjust your gain on it while monitoring the o-scope to make sure that you dont clip the amp.
