alan412 Posted November 27, 2008 Report Share Posted November 27, 2008 I'm planning on running 3 Rockford Fosgate Punch P2's. They are 2 ohm woofers, each rated at 250 watts RMS. According to Rockford's website when wiring 3 of these woofers to an amplifier they can either be as a 3 ohm load or a 1.34 ohm load. What i need help with is finding an amp that is capable of handling a 1.34 ohm load at 750 watts RMS. Any help is appreciated.

Thanks look into the sundown 1000ds, hifonics lower line or just about any amp that'll do 1000X1 @ 1ohm.

Thanks Actually if they're 2 ohm woofers and you wire them in parallel you will get a .66 ohm load not 1.34, and if you were to wire them in series you would have 6 ohms not 3 ohms. I don't know where you came up with that or where Rockford would say something like that but it's completely wrong. I'd check on the impedences of the woofers again because I don't think that Rockford even makes single voice coil subs that are 2 ohms. Check back and find out what you are actually getting.

He is right shades, didnt sound right at first, What threw you off is the fact that he said 2 ohm woofers, and not 2 ohm dvc's. x2 I bet you feel like a pro huh? I believe these are the subs he is speaking of? http://www.rockfordfosgate.com/products/pr...S&p_status= Since they are all dvc 2 or 4 ohm subs for the 8s, 10s, 12s, 15s. And the 10s,12s, 15s are all rated for 250wrms/500peak. Coil wiring configs. Quote Link to comment Share on other sites More sharing options...

Nightshade Posted November 27, 2008 Report Share Posted November 27, 2008 (edited) Yeah I thought that he ment that they were single 2 ohm subs since he didn't state that they were dvc's. Makes perfect sense now, but the guy shoulda included all the information since he was asking for help.
