    It's 2 ohm stable only when the channels are operated in stereo. With the channels bridged, it's only stable to 4 ohms. See the "Minimum Impedance Bridged" rating under the "Features & Specs" tab on your link.

    The Kenwood KFC-W3012DVC subs have dual 4 ohm voice coils. The best configuration for your amp/subs combo would be to wire the voice coils in series on each sub for an 8 ohm impedance and then parallel both subs to the bridging terminals on the amp for a final load of 4 ohms. It's safe for the amp and results in the best power solution.

    You could operate the amp in stereo with each sub connected to separate channels at 2 ohms. In this case, parallel both voice coils of each sub to an individual channel. In either case, the power to each sub will be the same.

    The amp you linked to in your other question will be much better than one.;_ylt=AtAIl... Go with the one I chose there. This amp you linked here will work 480x2 at 2 ohms but your speakers are 4 ohms, if you bridge the connection it will do 960x1 at 4 ohms but then you would need two 8 ohm subs hooked up in parallel.

    The amp you linked above could work if you just use it unbridged, it would be 320w x2 at 4 ohms per channel. The problem with that is you should always have your amp around 3/4 gain or less so instead of the rms 320w x 2 you would be looking at around 240 x 2. The amp in your other question I told you to get would be more around 300-320 per speaker and give you more boom. I think your always better off going with a mono amp for subs than bridging an amp for them, but if you can find an amp that does like 450-500w x2 at 4 ohms that would work great too it will just cost more.

    the dual Electronics BP1204 12-Inch 1100-Watt Illumination Bandpass Subwoofer is a spectacular product. in the experience that your searching for a sub with a lot of unpolluted sound then the 1100 watts height potential this automobile subwoofer has will provide a noisy and precise bass reaction.
