BIG...

I just bought this amp last week. From what i hear it is very effecient. ANd you are correct when saying "it is like having two amps in one".

IT IS stable @ 1ohm, people even run/burp these @ .5ohms on killer charging. The thing is beautiful, im my opinion one of the better looking large amps out there.

i assume its stable @ .5 ohm x 2 not once its bridged

although it would be nice to burb it at .5 x1 channel //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

.5 mono would be a long shot. The guy that owned my old amp burped it at .7ohm mono. But also had lots of batts

what type of voltage were you getting back there? also check it out with a multimeter first, make sure you're getting good voltage, even if you aren't getting any dimming or other symptoms. 9 times out of 10, big, current hungry amps like that blow up because your vehicle can't provide enough current.

you did do the big 3 right?

I sent that amp into protect once. but when i turned the car off and then back on it was fine.

I agree with Cochese. also check your ohm load //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
