It will give each sub about 90 wrms. and then you can run a set of speakers off the other 2 channels. Typicaly, bridge channels 3-4 for tri-mode. But read your manual on proper wirering. http://www.crutchfield.com/learningcenter/car/subwoofers_wiring.html?imageID=2SV C%5F8%2Dohm%5Fmono |

It's basically a useless feature IMO, any 2 ch bridgable amp can do it. To me it's just a line to add to the specifications of a budget amp. Fadhel - running 8 ohm spkrs with a basic 4 ohm car amp isn't a problem, but the amp will only give you 1/2 the power since the resistance is doubled. |
