I'm looking at purchasing a Rockford Fosgate 4-channel 2ohm amp and 250 RMS 4ohm subwoofer. Heres a link to the sub --> http://www.crutchfield.com/App/Mobil...75R3004&tp=115

Could I possibly power the 4 stock speakers and the sub with this amp? Would this be efficiently using tri-way mode?

It would work but you wouldn't have a front to back fader. You would be better off with a 5 channel amp.

No. The four speakers will be a 2ohm load on the amp(not rated in tri-mode) you could run just the fronts and the sub. You mostly hear the frount speakers anyway. You'd be better off with a mono amp and the 4-chan.

That makes since, I was looking at a mono amp as well. The RF Prime mono is another $130. I may have to find something cheaper bit I wanna get the most quality for my buck. Any recommendations similar to this setup?

Good luck with that.
Cheap and quality = Nope.
Cheap is cheap. Quality costs money.
Sure, inexpensive stuff works well for most people. There are reasons that you can buy a $4000 mono amp.
Save up some money and get a good quality piece of equipment.
