so how is it actually done? I'm pretty comfortable with splicing dicing audio wires and figuring out how to power the speakers and such. I know there are different cars with different premium sound systems like Bose... but I'd like to know how it's done for a stock non-premium system. I'm guessing an amp is required as well? just like to get an idea... thanks
my goal is to replace the headunit with a carcomputer.
