new system tech questions

[ryota]

let me start by saying sorry for my newbiness at this whole thing. i made a post trying to figure out which speaker to buy and am probably going to order 1 of 2 pairs tonight. i do, however, have a few technical questions before doing all of this myself.

a. i want to keep the stock head unit (i really like the stock look and being able to use the ipod jack between the seats) so i know i'll have to use a line out converter. i'm okay with splicing it into my wires but which wires do i splice them into. i saw the wire color diagram and i know i obviously use speaker wires, but does left/right/front/back make any difference

b. can 1 line out converter run to 2 amps or would i need 1 for each amp (one for 4 speakers and one for a 10" sub) and would i need a 4 channel amp to run to all 4 of the speakers?

c. which is the best way to run power to 2 small amps? i know from the batters through the firewall, but what am i missing before i go and do something completely useless or stupid?

d. just so i'm clear on this, i'm running the speakers wires to the LOC, rca cables from the LOC to my amp (for the speakers) and wires from the amp straight into the speakers correct? this would make those plastic clips that plug into the stock speakers useless and i can just get rid of them because it will be all new wires with the exception of the head unit to the splice.

thanks for all of the help and sorry about by complete retardedness. i swear i have searched to forums for most of my questions but a few still left me confused.
