Yashik, I am yet to decide on that. From what I have heard from my friends if you supervise the installation the installers do a decent job. Stayaway from SK Motors the owner is arrogant and isn't interested in answering your question about the equipment. Though he have good range of products to choose from. He pushes Boston speakers too much. Car Life in Sec 27 though not as big as SK motors but the guy over there is very helpful and answers all your queries about the product.
