The specs on them say they will run from 150-1000w rms. I was thinking of getting two rockford 851s amps ( 425w X 2 channels @ 2 ohms rms ) which would be 850 rms per speaker. Does this sound right? I'm pretty much a newbie at this and just want to make sure, or are there any other amps that would work better? Also I heard these amps take up a lot of power and was thinking of also buying some capacitors, how many farads would be good? Thanks to all in advance. |

Get a deep cycle Optima Yellow top to power that with a Alternator. Those subs are frikin huge. The Amps should power them just right (as long as you bridge). Is this your sub? http://no.kelkoo.com/b/a/ss_rockford_fosgate_frc-3206.html |
