I usto have 2 12' p1s but the specs between these and the p1s look the same how would the r2 and p1 be different?
A shopper on Dec 7, 2014
Best Answer: Different product lines. The higher model likely has a larger magnet, more voice coil venting ect.

this feels like a dumb question but will this do 150 watts rms from a Rockford amp? will it blow up or sound horrid?
matthup on Dec 18, 2014
Best Answer: Hello Matt,

The subwoofer will take it just fine; However, the problem lies with the User. If you do not tune the setup right, and/or if you send a Clipping signal in order to counter the lack of power, then That will harm the subwoofer. This is why we often suggest Overpowering a subwoofer, because you have the ability to dial down if needed.
