here are some pics of the amp in question: http://www.putfile.com/album/185437
the board looks almost identical to the rockford fosgate 360a2 on the ampguts site . The heatsink is different on mine and it looks like at one time it had a top mounted power indicator LED.Is this amp perhaps just a new version of the 360a2?There is nothing I can find on the amp at all to indicate what model number it is.I'd like to find some more info about this amp but its kind of hard when I don't really know what it is.any help would be greatly appreciated.

I also found a mystery RF amp but its a baby one. It is an 2.3 I think or maybe Z.3, bright red sink on one end & bottom with a silver square cover over the rest with texture stamped in the top. I think 2x30w and is dated on board 1998 IIRC. Need to find outputs for it or replacements, nobody seemed to have them. Only 4 TO220s. Could not find manual at RF. Lots of SMD inside, only about 4x5" or so.
Lol, I thought I looked on there! Must have missed it. Yes it is about exactly half that. If you cut the right channels off and made the PS a little smaller that would be it. I thought it might be good for tweeters or who knows. I did not know if it was a typical RF amp and under rated or not, or a cheap line? I think it is bridgeable but says nothing on it.
Yes it was a short run of their cheaper line. It is bridgeable into a 4 ohm load. Left positive and right negative, are the bridge terminals. I think they had special parts with rockford numbers on them. IRF-540 and IRF-9540 were suitable replacements. I do not remember if this amp had 4 N channel FETs or if there were 2 P channels and 2 N channels.
I dug it out, each channel has a P12P10 and a 36N06V. PS has two 36N06V. It runs and has rail voltage on right channel so I was going to put outputs in it. The P transistors must be RF parts I can't find, the 36n06v comes up IRFZ44E I think as a replacement if I wrote it down right. I also wrote down STP 36NE06. It says made in USA 5/8/96 and rail caps are nichicon 105C 2200uf 25v. According to that ampguts it would be 120w x 1 bridged, nice if I had two and they sounded good and it actually put out 100wrms or so. I think my alpine 2x30 is 90 bridged.
It does not look like anything has been soldered on board, but did have sink grease all over the sink clips.

Funny! i just repaired and sold one of those. mine had bad power supply fets. Nice sounding little amp! it isn't much to look at but perfect to throw onder a seat to run some highs. here is a link to the manual:

whats cool is that it gives you component values to modify the crossover cards to whatever you need.
i just sold a rare 5-channel model like this too and the guy that got it is very happy with it. he has it on 4 infinity door speakers and a kicker comp 12" sub. again, a bit ugly but great sound. the plug in cards versus potentiometers for crossovers might have something to do with that?
