I wantedd to know how complicated switching head units can be. I dont feel like throwing down 200 beans for an install if i can do it all myself, The amp and subs i know i can do, but teh head unit worries me. I would love to put in the Blaunkput (spelling?) San Fransico head unit. Any ideas? suggestion? comments? thanks guys! and if i need new harnesses or anyhitng, do you knwo where i can get them?
