Early 2000's Rockford Fosgate amp. 2 channel. Came out of a storage unit with others all tested working just haven't had the time to test a few and this one happened to be one of them. Can be cleaned up if you know what you're doing. When going to take photos one of the screws on the underside snapped off due to oxidation. Took pictures of the inside board to show no damage, rust, or oxidation has touched it. As is unit. Was informed by someone here on ebay the model is a Punch 700S. Kudos to them for the hands on identifying it. Otherwise, the older amps I'm familiar with and they're both reliable and generate the closest thing to what they're actually rated for.
