I have a 97` ford expedition with Alpine 570a speakers in the front and rear
doors. The head unit is a pioneer 3700mp and the amp is pioneer gm-3100t.
Should I run the front speakers of the amp and the rear off the deck, or all
four speakers off the amp?

Those who care about sound quality would probably tell you to run the fronts
off the amp and the rear speakers off the deck. This is because your rear
speakers should play at a much reduced volume (your "stage" should sound
like it's coming from in front of you). If you connect all four speakers to
your amp you will lose fader control (there are ways to attenuate your rears
using L-pads and such, but it's complicated).

Now, that being said, another school of thought would say just do what
sounds the best to you. So my advice would be to try it both ways (if
possible) and see what YOU like best.
