I bought these from the group buy and sold my car before I really put the system all together. I had powered them each for less than 5 mins with only 400 watts on them and didnt push them hard or anything like that at all - I had ordered a new amp for them but ended up cancelling the order. There is honestly no difference between these subs and brand new ones. They are all packed up in the original shipping boxes ready to go out. I need them gone. $200 shipped each.
