I recently went to Autotronics (http://www.autotronics.info)
, I was pleased with my service. Better than the twits at Best Buy. And my stock fader is finally wired out properly.
If you cant make it out to see Paul and live in Mississauga thats a place to consider.
I have also purchased from Radioactive, I found them good to but no install expireance there.
Too bad now I am thinking of a new trunk/sub setup. It never ends!
