Why so much. I would try another car audio installation place. I just had my 4GA amp wire ran through my car and another 18GA wire ran to my fuse box for $20. The wire was bought last year for $40. I know thats not everything you need wired but thats the jist of it, I can't tell you what else anything would cost to install cause I did the rest myself. Surely you could find someone to do it cheaper.
