Hello,

Looking for a bit of help.

I have just installed one of the O-Audio 500w bash amplifiers into an 80ltr sealed enclosure, with an Acoustic Energy AV15-X driver.

I am using the subwoofer pre-out on a Denon AVR-1910 amp for a signal.

Testing it for the first time, and after a quick set up I was playing the bass heavy intro to Transformers 2 with the amp set to -10db and the fuse in the amp has blown.

Could this be a problem with my particular amp, or something else?

Thanks in advance for any help.

Are you sure you have it wired correctly? The av15-x is dual 2 ohm coils I think, if you wired it down to 1 ohm you could cook the amp. Aside from that I ran my o-audio at full gain for awhile and never blew a fuse at all.

Pretty sure it's wired correctly. Wired in series, the negative of one coil to the positive of the other, then the remaining positive and negative wired to the amp.

FYI - I sent an email to OAudio just before I posted this thread.

I am a bit disappointed that they have not been in touch yet, fingers crossed I'll hear from them soon.

For anyone willing to try it, here is the audio from my Blu Ray rip. The issue seems to occur at about 28 seconds in.

Take care, this has caused issues for my BK Monolith and SVS SB12+ before my DIY sub!

Yeah, my new 18" LLT loved that movie. Just got done watching that earlier today actually. I'm sure my neighbors thought their house was going to blow down though.

If the fuse is blowing, then that means it is drawing too much power. Might be a bad bridge rectifier.

Thanks for the info.

I am pretty sure that my sub could have dealt quite nicely with the rest of that film, as it was performing well when watching the challenging scenes in Cloverfield.

It's just that couple of seconds of signal at about 28 seconds in that caused it (and my last 2 subs) problems.

Has anyone tried the file I have uploaded?
