Car audio and amplifiers?

[AndyN]

So I have a whole new audio system for my Nissan S15, I've got an active Bazooka sub for the trunk, 2 new 500watt Kenwood 6x9's in the back window, and two new 120watt Kenwood 4" for the front, a 720 watt Kenwood 4 Channel amp, and a Kenwood DPX503 deck.

Question, if I wire my 4 channel amp up to power all four speakers then essentially I'm not using any of the power supplied by the deck at all?

Could I instead wire the 700watt amp to the rear two speakers and turn the deck bias all the way to the front? Would this increase the decks power output to the two front speakers ((22rms/55watt)/each of 4 channels) then to 44rms/110 x 2 channels. Thereby maximizing the power to all 4 speakers?

i think what you should do is just use the 4 channell amplifier becuase its meant for 4 speakers or a subwoofer if it is bridged and has lpf, why bother with that if you already have a amplfiier?
your not using power form the deck, your just taking the sound outputed and then amplifying it
yes if you turn the faders then it should make it abit louder but just use the amp, dnt b extra by doing that if you already have the amplfiier
