Have a older style alpine type r 12" and a kicker cvr 10", the surround is starting to come loose on the type R but it works fine. In a bind for cash so selling the type R for 60$ shipped and the Kicker Cvr for 35$ shipped. The cvr wire from the coil to the terminalcame loose but i taped it to the wire and it works fine nothing wrong. Buy both for only 75$ shipped!
