Isaac Coker goes above and beyond to ensure the customer buys the correct equipment, takes the time to explain options, gives accurate and reliable advice about products. Isaac also spends time to ensue that the customer understands, and is happy with the system purchased. I received all manuals, boxes, remotes etc! First class service and that's why I keep coming back. I also let friends and family know where I got my system. I've had nothing but complements about how good it sounds.
