sell the two crappy amps you have now and buy a better amp used from ebay. shouldn't cost ya much if anything.
this is why it's best to do your research before buying things, and buy the right things the first time, even if you have to save up to do it. impulse buying or letting money burn a hole in your pocket usually ends up biting you in the rear.
