Don't want to write a book on here, so I'll just paraphrase..
Went in to get an amp installed. They left wire strippings everywhere on the floor, the amp was not not mounted in the discussed location, the amp was not properly grounded, my car was not ready at the agreed time, and the way that they ” tuned” the amp was horrible. Cheap price..cheap work. Ehhhh. 1 star... Disappointing
