What amp to power a sub?

[iGreek]

I have a Older Rockford Fosgate 12" Punch Z Sub with a 400 watt max, 150 Watt RMS and has 8 ohms. If I were to run this by itself, what type of amp would I need?

I've got a 1000 wat amp for sale for cheap ($80) that would power that sub wonderfully. Just don't turn the amp up all the way :). Let me know if you're interested.

Dude, anything from fry's that you have heard the name brand before... You could go asking for a mono-block amp AKA D-class.... they are sub only amps and are very efficient
