I am planning on installing new speakers and an amp next weekend. I had been going with the approach that since i am gonna be tearing everything apart i might as well run my own 16 or 14 ga through the car. A bunch of people locally have been telling me to just run a 8 wire loom to the head unit and splice into the stock wires. This sounds a ton easier but also kinda sounds like some BB corner cutting technique. Am i going to lose much on stock wiring vs my own with just 60W rms on each channel?
