Guys i putting in a new audio system in my 011 WRX and was wondering if i could use the stock wiring for the PDX amp with ut any problems. reason i ask is because i am not going full out and don want to run wires through doors etc.
I was thinking of using the Metra Quickcable 18-gauge 4-ch. speaker wire
from the amp back behind the headunit back into the stock harness. Will this effect the sound so badly that i should not do this or is the 75W/ch not a problem for 18 guage? I want it to be easy and neet install.
