what do I power a 15 inch with?

I just picked up a Blaupunkt PA2150 for $80 plus shipping. Its a 2 channel that's bridgable to 400watts @ 4 ohms.
I came with a birthsheet that stated 473watts @ 13 volts. Pretty nice setup and includes remote bass gain.

Just got it in so can't comment, but the specs look great for the price.

that sounds nice, I do want alot of bass but 700 watts might be overkill for what car i'm planning on putting the system in. I'll have to read up more information of both of these amps

I think more around 4-5k watts would be overkill. 1000rms is great for a daily driver... then again it all depends on the installation.
