425 watts RMS x 2 at 2 ohms 850 watts RMS x 1 at 4 ohmsSUBWOOFER HELP!?

Since you want two subs, then you should look for a pair of subs with 2 ohms resistance each. This will give you 425x2 Watts rms (in 2 ohm stereo).

Alpine Type-R SWR-1242D. These are excellent woofers for sealed or ported applications. If you wire a pair of them series/parallel, than you'll get a 4 ohm load at the amp.

Let us know what your looking for...SPL, SQ, or both. Also how about a price range. Thanks

if you are running subs you would want to bridge the amplifier so it would be 850 watts at four ohms. single woofer --------------------------------------… single 4 ohm voice coil directly to the amp dual 2 ohm voice coil in series 2 woofers --------------------------------------… single 2 ohm coil series with other woofer dual 4 ohm coil series each woofer them parallel speakers together 400 watts rms power handling each is good. power handling is not per voice coil but for both coils on a woofer so what it says it what it takes whether it a single voice coil or a dual.
