hi, my friend just purchased a bunch of stereo equipment from somebody, and with it came a fosgate 200.2 and a fosgate 225.2. can any of you give me specs of these amps or a like to them. he wants to run 2 12"impulses of one and 2 12"comps of the other, these should be plenty of power eh? i have no experience with fosgate amps, but any info would be apreciated

Are you refering to "Rockford Fosgate" or just "Fosgate". Fosgate would be an amp from sometime in the 80s or earlier before they merged with Rockford. Are there any serial #s on the front or back of the amps? Most RF amps are rated like this, ###.% , ### is RMS watts while % = by that many channels. meaning your 200.2 is 100 watts RMS by 2 channels.
100 good RMS watts can run most subs. But if you really want to work those impulses or comps you are probably going to want a bigger amp. Here is a link to the amp on eBay, is this what you have?

I'm also not sure if the amp can be bridged and run at 2 ohm. But that might be a possibility.
Just my 2 cents.

I can't find the birth certificate for my old 200.2, but I do know that it was just under 500 watts x 2 channels RMS, at 4 ohms.
Before I got so power hungry, and realized the efficiency of the D class amps, I ran a few systems with my 200.2.
It ran a pair of RF Punch DVCs, a pair of Kicker Solo Barics, and a pair of Eclipses. So from personal experience, yes this will run them fine, just make sure his electrical system is upgraded, as these amps pull a ton of power to work properly. Example - 105 Amp alternator was not enough to run 200.2 with everything else stock. Once I upgraded to 160amp alternator, I was fine.
As for being bridged, you can run 4 ohm mono, 4 ohm stereo, or 2 ohm stereo.
Also - Check the 'card' that plugs in under the amp. This 'card' is the crossover, so make sure it's in properly, or you may end up trying to run the subs at 250Hz and up. Not that I would ever admit to doing this, just offering my advice.
