Boss Amplifier ??

Hey, I've got 2 Infinity subs that are 275w rms @4ohms each. I need a amp and don't really have the cash. I saw this Boss Ripper series amp really chep. The Rip-495 700w (bridged) and Rip-595 1000w (bridged) wich is really more than I need. I heard that Boss is over ratted, is that true??? Their specs are really nice though, http://www.bossaudio.com/
I found both amps at less $200.00
What do you guys think of Boss and their amps??
