Sorry, took a couple days to get back - tried to upload the pictures straight from my phone but they were too big...
Lee - I'm looking for something I can just run bluetooth from my phone or maybe hook up a radio/CD player to and make decent sound from my speaker so I think an Amp might be able to suffice on it's own. Thanks for the rec on the Samson Servo, those don't look too bad pricewise.
Also, since you can't really tell from the picture, the speakers are a pair of old Peavey 112-Hs and just take a standard mono jack cable.
