I am running a kicker zx400.1 and zx200.2. Was going to run 4awg power to back where amps are (about 10-12ft) then 8awg to each amp(maybe 2-3ft) through a distro block. The manual for zx400.1 recommends 4awg power and ground (the inputs are for 4awg), of course zx200.1 8awg pwr/ground. I was going to be safe and run 4awg from the distroblock to the 400 watt amp as well as 4awg ground BUT...cant find a distro block that has a 4awg in and 4 awg out with an additional 8 awg out. Looking at different charts at 400-450 watts I should be ok with 8awg power and ground but i just want to be sure for my 1st install Every distro block I find has 4awg in and two 8 awg out...even though the manual and holes are for 4awg, i feel the 8 awg at a short run from the distro block should do correct?
