OK guys, I'm getting the final touches for my system that I will be installing next month (which is when i will be able to afford the head unit).
Here's the list of components:
Pioneer DEH-P5800MP Head unit
Infinity Kappa perfect 6.1 component speakers (for the front) - 100W RMS
Infinity Kappa Perfect 10.1D Subwoofers (2 of them) - 350W RMS each
Infinity 7541a 520W 4 channel Amp (for the 6.1's)
Infinity 1211a 854W Class D Subwoofer amp (for the subs)
Now my questions...
1) I was planning on running a 4 gauge power wire into a distribution block to power both amps. However the distribution block I was looking at only has 8 gauge output's. So would I be alright with an 8 gauge wire to each amp? or should i go with a 1/0 gauge power wire and get a block that has 4 gauge outputs?
2) I'm thinking I may eventually add a set of Infinity Kappa 693.7l 6X9's (110W RMS) to the rear deck. Would it be a good idea to run those off of the 7541a amp when I already have the 6.1's hooked up to that? Also, would I need to kick the power wire up to a 1/0 with a block spiting it into a 4 gauge? Or, once I hear my system I'll realize that I don't need these speakers?
Thanks for your help guys
i think you should go with the 1/0 guage to the back and split it to 4 guage, bigger wires are less resistance so ull get more power, maybe not a noticeable amount more, but still, overkilling wires isnt bad for anything, and it has its advantages...but about that amp, if its powerin the front speakers, does it have like, a crossover or whatever you want to call it so that the back speakers will get the back speaker signal, cuz you dont want to get the front signal comin out the back, thats just bad sound staging

you want to bump, then they will bump and hit real hard and a lot good. 
LOL
Yes it does...
This is on Infinity's website:
The 7540a comes outfitted with a variable 12dB per octave electronic crossover allowing you to optimize system tuning based on speaker location and accompanying loudspeaker components
