I am thinking of buying one JL Audio 12W0 sub. I also want a Rockford Fosgate amp but don't know what wattage to get and the model number the amp should be. Can anyone give me some suggestions. Also, I want to put the sub in a bandpass box, any suggestions? Thanks.

 

~500w in a sealed box. IMO

 

A Punch 250a2 will be more than enough. Make sure that you get a 12W0-4.
