hey,

im currently running a sub with a amp thats 300 watt rms ( 20 amp fuse) and im just about to wire up a second amp to my front speakers. which is 70 watt rms ( 20 amp)

the power cable for my sub is 8 awg and the same with the earth. if i use a distribution to run the second amp will that power cable be able to handle it? or is it worth going to a 4 awg power and earth cable?

any ideas?

thankssss

same should be ok mate.... but change it if you wanna.... maybe upgrade the fuse though

im not sure if that was helpful or not=] as long as im not sacrificing quality or power im happy.

upgrade the main power feed and earth to 4AWG cable and then use wither 4awg or 8awg to each of the amps via dizzy blocks.
