Ok, I have a RCSB with a custom built box/console tuned to somewhere around 35-40Hz (I don't remember). My problem is that I just installed it with a 10 inch Kicker CVR about 6 months ago and the CVR is just about dead. At lower volume it will just lock up and not do anything but if I push on it it will start again. I guess the voice coils are bad. The place I bought it from will swap me a new one for $50 so I'm not too worried. I just want to find out what caused it to blow so soon. It is rated at 800 watts peak and my amp is only a 300 watt amp so I know it isn't being overpowered. Any ideas would be great. Thanks
