I picked up this amp today, and cant find any info other then 125rms x4. Anyone familiar with it? Also, everything I find is with black heatsink. Any one know anything about this gold heatsink?

I dont know a whole lot about the amp, other than the Pink Logo..CRUNCH,and remembering those were just after the Black Beast of amps,and were rated at 12.9v within the same era as the USA US ACOUSTICS SERIES II,that was made by ZED AUDIO.Ill bet that amp is really clean for mids and highs,and is very under rated..Shes a Beaut!! Its a great amp for sure.I wouldnt mind having it..lol..Id run it on my mids and highs in any set up

I put this in my car today, the 4x125 is likely at 2ohm. I ran it at 4ohm, and it sounded very comparable to my Audison srx4 that I normally use (65w x4 @4). I was surprised how clean this amp sounded tho. Nearly as clean as my Audison, thats pretty impressive
