1/0 gauge.

Don't get a cap, do the big three(do a search be4 u ask) and your blazer should be fine. As far as wire size, I'd say that's on the edge of 4 or 0/1. But i'd go 0/1 also to be safe, or in case of an upgrade.

4AWG is fine for both power and ground, you don't need a cap. Only get a bigger wire if you plan to upgrade, otherwise it's a waste.

Yeah 4 guage will be perfect. I used 8 guage for a similar system and it was plenty.

4 gauge is generally the best way to go, but in reality 8 gauge would be fine as well, 8 is much easier to work with and 4 is for when your stepping up to the high power/current amps and subs

4 gauge would be more ideal. but if you already bought the 8awg, thats fine too.

if your using 4 guage as a main power line in a blazer its only good for 50 - 65 amps total.
