dual amp setup, rca cable question

[reed dollaz 10+ year member]

ill be running an EA2000 (component amp) and a kx600.1 -- i have one run of rca's going to my PA4212 (replacing that with the ea2000) the EA has an RCA IN and OUT. can i take my RCA's from the HU and put them into the IN on the amp, and another set of rca's coming from the OUT aux and run it to the input of my kx600.1 or should i run a new set of RCA's from the subwoofer output on my headunit. ill eventually use the PA4212 again when i get a better rearfill, so then ill need to run another set of RCA's.

also, with these two amps (EA2000, 600.1) will 4ga wire be suitable if i split it to four 8ga wires. my distroblock is 4GA in and four 8GA out. will it be good enough to send my L7 10" 600watts?

Run RCAs from sub preout on h/u.

I'd go 1/0 to two 4ga. Also leaves headroom down the road.

dont have any 1/0 and dont have money for any ATM, or i definatly would. but will the 4ga and 8ga be suitable to power approx. 800 watts? 650 to the L7 and 150 to the components

i would most deff. run 0 gauge with 1 L7, even if it was 2 L5's....

do they make any distro blocks that are 4ga in and 4ga out? never seen any. or can i just one that 1/0 in and 4ga out, but just use my 4ga wire. would it tighten down enough to hold the smaller power cable?
