Have any of you seen this before?

Was in the boys car driving with him tunes were medium loudness. We were able to talk over them. Suddenly speakers sounded funny and shut off. By speakers I mean subs. We get back home and amp fuses blown. We replace fuses subs come back on, sound even funnier and then pop. Fuses gone. Allow me to add, after the first pop of fuses, we checked all cables and wires. No shorts. Started checking subs and every one of them showing open. Not dead short. open as in there is no circuit from positive to negative. How do four subs all do the exact same thing at the same time. I am befuddled. I mean, what are the odds? Oh yeah, 4 sundown E8 rebuilds and a Sundown SAE 1000D. Does anybody have experience with something like this? Trying to figure out how this happened and how to avoid it in the future.. Amp gain at like under 25% subsonic up high enough so that the woofs would not break up and pop. woofs wired for a dcr of 1 ohm. Anything else I can tell you let me know.

Please help!!

thanks,

Cub

check the tensil leads mabe those broke of the solder joint let loose

change the ohms try 4 and see what happens... sometimes the amp just cant handle 1 ohm for long periods time... the amp just might be getting old. Good luck

[canuhearmenow 1]

are your speaker wires grounding out somewhere that amp should handle 1 ohm all day and if they are reading open there is something not right those coils are beefy as hell i cant believe the 1000D burnt them something else is going on check the speaker terms on the E8 make sure that the wire isnt poking threw the term to the basket

also try unhooking everything but power and see if it pops the fuses if it doesnt hook the RCAs up and try it then speakers

Sorry I didn't expand. Amp is working fine after fuse replacement. I tried it at 4 and 1 ohm loads on a different sub. I wiggled the terminals on the E8's When we were installing these woofs I made sure the wire was stripped 3/8" to avoid shorting to the basket. I am really trying to figure out how this happened. The same thing on all four woofers???? I am totally stumped. I set the whole system up to handle a 16 year old and lot's of rap music at maxed out levels. It really has me stumped.

[canuhearmenow 1]

have you taken the woofers out to inspect them ? `i know the subs take alot i had a SAZ-3000D @ 18V on 6 got a 146 in a ghetto box so i know they take alot i am lost if they read "open " what did the triple joint look like ?

Not sure what the triple joint is. I am in Arkansas this week. When I get home I will check. One sub I can believe. But all four subs at the same basic time same issue? I should buy a lottery ticket and stay away from any tall metallic objects when it's cloudy. I think i am going to send them back to Mike to have him look. It had to be some type of common item that failed between all four of them. When I find out, I will let you all know.

Did you put a DIMM on each sub or just all 4 wired together?

[ABXX49 20]

You're blowing the fuses on the amp right?

[cubdenno 0]

To answer Spy yes and Yes. I use my DMM I tested all four or actually each pair then each one seperately.

To answer abxx... Yes the fuses blew twice. now I CAN CONNECT ALL FOUR WOOFS AND NOTHING HAPPENS (OBVIOUSLY AS THE COILS I AM GUESSING ARE OPEN) and the amp will safely power a subwoofer still as I hooked it up to mine which is wired for a 1 ohm dcr.

[ABXX49 20]

Weird. So the amp powers another sub. Have you tried powering each one of the subs individually on the amp?

The amp appears to be fine. What I am wondering is... Did one of the coils short causing a power surge that say damaged the other speakers the first time the fuses popped. Then when I replaced the fuses, the now damaged other speakers died during a second surge that popped the fuses. That is a hypothesis I have. I do not know what has caused this. Like I tell my friend this is crazy.

I tried powering other speakers on the 1000D. I tried a toyota factory 6 ohm 6X9 first. You know... Just in case. Then moved to my TC3000 15. I tried it first @4 Ohm dcr then 1 ohm DCR. It worked fine. New fuses and all.

The E8's, I did not try on an amp. I just tested them with a DMM. Oh wait... I did have them hooked to the 1000D again before we tested amp on 6X9. They did not play. I first thought it was the amp. I seriously did not think all four woofs would have what appears to be the saqme issue.

This is by no means a slam on the E8. The thing is a beast. four of them just plain kill. We did buy four of them from the first batch that jacob sold to Mike to be rebuilt. I am in contact with Mike. Or at least I will be when I get back home. In Arkansas for work now. I am just asking to get something I missed or overlooked. I keep saying it. This is just strange.
