Absolutely no good!! The salesman that helped me wanted to sell me a $120 car alarm for for $375 plus a $60 install. I bought some over priced Kickers for my car doors and now my switches and buttons on my doors won't work and/or fell into the doors itself. They also crudely installed some 6×9's using only two screws on each speaker from the bottom which makes them rattle and shake causing the wires to disconnect constantly! Spend your time and money wisely, go somewhere else.
