1. Is there some kind of ratio of power to balance your sub and front speakers? I plan on getting a sub rated up to 250 watts rms (http://www.crutchfield.com/S-py71l9Xu6Ry/cgi-bin/ProdView.asp?g=67600&I=1081030W) and the components are rated up to 75 watts rms (http://www.crutchfield.com/S-py71l9Xu6Ry/cgi-bin/ProdView.asp?g=76300&I=1085000CS).

2. Is this amp (http://www.crutchfield.com/S-py71l9Xu6Ry/cgi-bin/Prodview.asp?c=3&g=120&I=489AP1040&s=0&cc=01) capable of powering both the speakers and the sub, or would I need a second amp?

2b. If it is not powerful enough, I take it I would need 2 amps, one for the speakers and one for the amp. Would this create too large a strain on a stock electrical system (battery and alternator?)

I really hope the original amp could run both, because then this is definitly within my budget. If I need a second amp, the components will have to wait...

Possibly, an amp like this (http://www.crutchfield.com/S-py71l9Xu6Ry/cgi-bin/ProdView.asp?g=120&I=236T564) would be enough to power everything, thus eliminating the need (and space) for 2 amps, although the price is similar to the cost of 2 amps.

Even the single more powerful amp would push me over my budget...

3. Im looking for decent SQ, not SPL. I mainly listen to indie rock (bright eyes, death cab for cutie, the faint, q and not u). I don't need earth shattering bass, but I have no idea what 100 or 150 watts to the sub would sound like versus 225 or 250.

If I ran 225 or 250 to the sub, and it was too much bass for me, how do I turn the bass (or its power) down? I'm almost embarrassed to ask that one...

they make 5 channel amps something that does 50 watts rms by 4 and then has a dedicated subwoofer channel rated at 200 or so watts, now i dont know how good they are cause ive never tried but it seems like it would fit what you are looking for.....

I personally like to go with separate amps for everything. 2 subs 2 amps and a seperate 4 channel amp for doors and 6x9s. This way one amp fails on its outputs or just blows somehow. You still have 2 amps left for example while the other gets serviced.

I do the same thing, I have an amp running my 6x9s and I have two amps powering my two subs.. very worth it

I love my 5 channel amp. They're extremely easy to set up. You don't have to deal with distribution blocks or anything of that nature. If you don't have more than 1 or 2 RCAs you don't have to worry about splitting them up between 2 or more amps. Mine supplies plenty of power for my needs and it sounds great.

50 watts PEAK, not RMS. You probably get anywhere from 17-22 watts rms out of the HU.

And your amp is going to be 444 ? watts peak to all 4 channels. It is probably 100 watts max per channel, and something like 40 watts rms.
