sub woofer wire

ok so can i or not? ur getting me confused

"the 8 awg is to small for 2 amps. it will not let enough current get to the amps. if you ran 2 8awg wires one to each amp that would work fine"

???

I understand what you mean that you had someone install it...

8 awg should be fine if....to find out take your rms of the amp...?...say 400 divided by your cars idle voltage...say 12.6v....you get the ampsof amprees your amp is pulling which in this case 400/12.6= 31.8amps

you would need a 8awg wire running between 10-13feet according to IASCA's gauge chart

so you should be OK

so it  is ok for me to take the 8 awg, that is already instaleld to my single amp, and cut it and install a distribution block and have two 8 awg wire out, one in each amp?

lolz just tryign to verify, before i work on it and get screwed lolz

^_^

so all i need to do is take out the 8 guage that is already hooked up, then switch it to a 4guage, and then take that 8 guage wire, and cut it in half, 1 to each amp,

so do i need to upgrade the rca wire? ground wire?

Do what you said except use a distrobution block of course for your power wires. You can ground your second amp the same exact way you did for your first. You can ground them to the same point also but make sure you have a good clean ground so your amps will work their best. You shouldn't have to upgrade the rca wire.
