OK.. I want to upgrade the factory speakers in my car and I'm sort of confused about something. I was looking at a local sound dealer at some speakers and the rep showed me a nice set of speakers that was tempting.

I asked him what RMS power the speakers required and he said 50W. Well I explained to him that the amp I had only did 30W RMS on each cahnnel and he said that it wasn't a problem, I could run the amp at 14.4V. Well here's the amp I have:

Alpine V12 F357
**RMS Continuous Power (Watt) at 12.0V 4ohm; Stereo (0.08% THD) 30Wx4+(0.3% THD) 100x1 2ohm;
Stereo (0.3% THD) 40x4 Bridged 4ohm; (0.3% THD) 80x2+(0.3% THD) 100x1

**14.4V RMS Continuous Power 4ohm; Stereo (0.08% THD) 50Wx4+150x1 2ohm;
Stereo (0.3% THD) 60x4 Bridged 4 - (0.3% THD) 120x2+150x1

He is right, if I ran it at 14.4V then I would get 50W on each channel. BTW, I'm running it in 5 channel mode and I want to upgrade the 4 factory speakers (1 on each of the other four channels) since i have a sub on Ch. 5.

Now my question is, can I run it in 14.4V mode and how can I do this?
