Item(s) Description/Condition: Great 4 channel SQ amp. Been sitting in a closet for some time. Took it out and cleaned it up. Powered it up today on some cheap JBL bookshelf speakers and almost decided to keep it. Man this thing sounds good. It is huge though, so if space is a problem, this amp is not for you.

Amazing amp here. I wonder if the rear channels bridged would push my W7 10 adequately . Always wanted one of these

Any needs for trades?

Not really looking for anything... But, I could use a pair of 3" or 4" mids, such as rainbow vanadiums or scanspeak 12M. I could add some cash if you had the scanspeaks...
