ThatRockfordFosgateGuy Posted July 30, 2012 Report Share Posted July 30, 2012 I Have 2 Rockford Fosgate P3 Subwoofers, and They Are Dual 2 Ohm That Handle 1200 Watts but The Amp I Want Is 1500 Watts, But It Has To Be 0.5 Ohm Stable To Get The Max Power... Some Amp Ideas...? Thanks Link to comment Share on other sites More sharing options...
BobbyG2 Posted July 30, 2012 Report Share Posted July 30, 2012 Wire them to 2 Ohms, get an Rockford bdCP 1500 You'll get a little better sound quality and a lot better efficiency out of it than if you wired your subs to .5 ohms. *New vehicle and system coming soon.* Link to comment Share on other sites More sharing options...

OP look at sundown DD AQ DC audio SKAR Its called Constant Power for a reason 1500watts at 2ohms no problem its called box rise. read up on it big man. i hope you realize when you wire your 2 D4 12s to 1 ohm you are probably rising to 2-4 ohms and utilizing that constant power you paid for. but when you wire to 2 ohms that BOX RISE puts you 4+ohms most likely and you will see 1k on those subs if your luckily. or you may get lucky and not have a lot of rise but you will still be over 2 ohms. learn a thing or 2 before calling someone out.

BobbyG2 Posted July 30, 2012 Report Share Posted July 30, 2012 Was judging by the guys name and recommending an Rockford amp for him. He shouldn't lose too terrible amount of power with rise. It's rated for 1,000 at 4 ohms. And Rockford just like all the other companies listed underrate their amps. I guess if he's worried about the 500 watts effecting how loud it is, he could build the box a little bigger to get more efficiency. *New vehicle and system coming soon.* Link to comment Share on other sites More sharing options...
