Hello. I have a DEI Studio 3124 12" 400w RMS 4 OHM single VC sub-woofer and I need to get an amp for it. Would it be best to get an amp that is also rated at 400w RMS? Right now i'm looking at the Rockford Fosgate Punch 401S. It's bridged RMS power is rated at 400w x1. Would this be a good match? Thanks. -JP

 

 

???

 

is it rated 400W RMS at 4 ohms?....if so then you should be ok...even if not, that amp should still be fine, just know the limits of your sub!

 

Sounds pretty good.

I am running 2 300 watt JL subs off a Rockford Fosgate Power series 451s amp, and even that does a decent job, though the subs could definitely take more.

But yours, nice match.

 

i would try to go right smack dab between the RMS rating and the peak rating of ur subs. Take me for example. I am running 2 Alpine Type E's (200 RMS 600 Peak) with an Audiobahn 800 watt mono amp at 2 Ohms. 400 to each. The subs slam and dont distort at all.
