It doesn't matter what type of speaker terminals the amp has. For something on the cheap I'd check thrift stores or if you have Craigslist that serves your area for a good buy on a stereo receiver. Audio Source sells cheap amps that seem to work well. If you are handy there are some do it yourself digital amp kits. I don't have any links but a couple guys here are into them. Do you have any other gear or just the speakers? If no other gear you should get either a receiver or integrated amp.
