You get what you pay for.
Stick with a name brand 4 channel amp if you are hooking all that up. Most are stable down to 2 ohms anymore. Find what you like and can afford from Rockford Fosgate, Eclipse, JL Audio, Concept, Alpine, etc.

how about you post what the rms ratings are of those 5 speakers and we'll go from there.

well im sure what would be the best for your speakers but i have ran many amps and i find that infinaty makes a pretty good amp. had no problems. it they are pretty cheap. but bring nice performance to your ears. and it would help what brand of speakers you got.

Im assuming that your Watt Ratings are Peak for your speakers. Run 1 4ch and 1 Mono Block Amp (2 amps) or that 5ch.

Well typically the RMS rating is half of the max power handling. I would find a nice 4 channel 250-400 watt amp that is 2 ohm stable and go with that. I myself have a 5 cahnnel amp that is 2 ohm stable with a sub channel as well.

thats why i said typically. It makes it easier to choose an amp IMO to do it that way.

As long as you have a reliable brand amp (Doesn't overrate power numbers or do shoddy things like get the Power ratings at 16V or something) and have an amp that does around the correct RMS wattage, should be no problems.

IMO, ditch the rear speakers. Oval speakers distort easier, and rear speakers screw up imaging. Worried about passengers hearing the music? You have a decent set of 6.5" comps in front. If they want to complain, then let them fork over the dough.

Just my opinion though. Imaging is important to me. You may THINK rear speakers make it louder, but all it did was cause a bunch of cancellation issues for builds I have done. Sound deaden behind your door speakers and you will have a ridiculous increase in midbass response too.
