Advice on amp for first time system

[tanders12]

My situation is a bit unique. My stock head unit has no AUX input, and since that's all I will use I don't see any point in buying a new head unit. I have a 2005 Buick LeSabre and the wiring harness on those things is all tied into the security system and stuff so I don't want to mess with it. Thus I'm looking for a solution to wire a 3.5mm stereo jack directly into the amp. The stock speaker setup is:

2x5.25in front doors, 2x4in rear doors, 2x(6inx9in) behind back seats. I have a Rockford Fosgate Punch P1 that I want to hook up. I will also eventually be replacing some if not all of the stock speakers.

From the reading I've done it seems like a good quality 5 channel amp would be the way to go. I have 2 main concerns:

1) In order to hook up all the speakers I would need to "bridge" the rear door and far rear speakers together, correct? Would it be better to just not hook up the ones all the way in the back?

2) What's the best way to split the stereo signal into the proper lows, mids, and highs? Is there a crossover that will do this or should I get an amp with a builtin crossover and physically split the signal?

you will want to get a 6 or 7 channel EQ at a minimum, for proper staging

I was hoping to avoid using s head unit altogether. On my car the wiring harness for the radio is all tied into the security system and other junk, and i didnt want to risk breaking anything. Also i figured why pay more money for something i dont need when all thats necessary is something to convert a stereo signal into line level component signals?

tie in on the front speakers with a loc,then run the rca to an eq,then you will have 3 sets or rca's out and an place for the aux.easiest and cheapest way to do what you want.just wire the eq to turn on with the ignition.

what I did on my dads motorcycle is the hu is actually his iPod touch, downloaded the best equalizer available, then from there ran an aux to a 3.5mm jack into rca adapter. from there the rcas went into a line driver (pac can be had with shipping on ebay for $24 shipped) then from the line driver i ran rcas to y splitters then into the 4 channel amp, actually sounds amazing.
