sound of tri-state is the best place in my mind to buy electronics and car audio equipment. I bought everything for my cars there and am very pleased with the service, quality products and professionalism of the staff. I deal with Iassac from claymont and he has always gave me stright advice and always remembered who i was when i go there. will deffinatly return for any thing i need for my home or autos. They also never try to sell you products you dont need like some other places that want to just make sales, I think they making returning customers is more important and having that word of mouth of being a great place to shop.
