I just bought two 12'' audiobahn subs. Their 400 watts RMS and 800 watts peak power does anyone have any suggestions on a good amp for these subs?

 

I would take those back.
They are over rated. And I don't mean as in quality. Quality is already crap.
( I mean as in watts). Don't fall for high power ratings. Buy quality.
I would'nt buy a sub or any other equipment without a "CEA" rating.
Only top companies use this rating. Many half ass companies say they have high input but they can't prove it. They are misrepresenting.
Look for the best, not the most.

 

As you can see your post had 40+ looks but no replies.
People just had nothing good to say. That says alot about your subs
