if not can you show me one on E-bay that would be good.
~~thanks

That Lanzar one is 4 channel. It could work, but a 2 channel amp would be ideal just for simplicity sake. If you're looking for a decent amp at a decent price. Check out the Hifonics Brutus 1000 watt mono amp at www.woofersetc.com it's rated at 1000 watts RMS at 1 ohm.

the white lanzar is a very good amp. lanzars are a little bit of an old brand, but the amp does kick ass. you could just bridge it.

What is better for my 2 500W subs?

Legacy is sub par equipment. I doubt that those ratings are even RMS, I bet they are max output ratings.

All of those amps are overrated, which means you'll never get the output that they tell you they give out. The hifonics amp would be an excellent choice as GScivic7 said. But if your budget is around 100-150$, the Lanzar is better than a Legacy. You could look into Power Acoustik as well, they make fairly decent amps, but with the same type of overrated specs.
