|Not only am I a fan of the product I purchase (ALPINE SWS 12D4) or the price which is excellent, but most importantly the prompt delivery, and overall customer experience. I would and will continue to send people to onlinecarstereo.|

|For the money paid it's worth it. Overall performance is just ok. It will leave you feeling for a tad bit more bass, punch, etc. Lows are not that good, rolls suck. If your short on cash, its a good buy. If money is not an issue the type R is a better bet.|
