Phoenix Gold Phorum

OK guys, fried one of my Rsdc 12s 2 weeks ago, with a hifonics Brutus, so I ordered 2 new hifonics Atlas subs, just got em in and turned it on without even giving them much juice, and pop!! One of them literally domed right out like a bubble, LOL, wtf happened?? Defective voice coil?? Have warranty on em, thanks

same side that blew the RSDC? how are they wired?

Paralled for 1 ohm, instantly popped right out! LOL, I'm a electrician so I know electrical, manufacture defect?? Buddy that helped me used to compete etc, said he'd never seen that

just because you competed, doesn't mean you know what your doing-

He knows what he's doing, wired right, just wondering if you guys have seen this happen on brand new sub, other one is fine, running 1/0 for power with 12 awg going to subs so good wiring, bad voicecoil??

There's scratching and friction when I push it in and out

??????? Something??

Yer having all sorts of bad luck with woofers so I have to think that they are being wired wrong in the first place. They aren't going to warranty a woofer that's been "abused" or installed incorrectly..... Can you take pictures of how things are wired so we can help ya alittle better......

possibly fried output, check output current at speaker connection?

Rsdc worked fine for 6 months though

I,d suspect the amp

Brand new amp though, had quite a bit of boost and gain before though, still wouldn't explain why the sub just popped out though! LOL, especially when other one is fine and they are paralleled

Would the amp going into protect mode right away when the rsdc fried mean its shot??

And how do I check the output with a bad sub? Risk the other one??

Problem solved, you over drove it dude

Ya bit that doesn't explain new sub, no boost and barely any gain when I powered it up, took 5 seconds and pop! Bulged right out, bad coil??

Guess I'm lost

Which brutus amp do you have???? The site seems to say ALL of the mono's are brutus' but different models......

Cant you fry mosfets in an amp if you have a blown speaker running on it too long?

D.C. offset @ speaker terminals?

Thing didn't run more than a minute with the fried sub, and it shut down anyways, ran parallel anyways and the other sub is fine ya know

Its the bxi 1600,

Gotta be flawed sub

From what I gather it sounds like the outputs to the amp are shorted.

Subs don't move out or in on their own without a signal from the amp telling it to do so.

That still wouldn't explain other new Atlas being fine though
