Hi all, Just took ownership of a brand new G6Et but the audio is lacking. I have a old kicker 600.1 mono block laying around the house I would like to install (as well as a new 8" sub). I have been reading that it is possible to use the line in/out (was explained better in another thread) and make up some RCA inputs. My question is can you use the existing power/earth wiring or will I need to run a new line? Ive been though several custom sound installs and really dont want to go through the headache of ripping out the cars guts if I dont have to. Cheers
