Infinity speakers for KK
I have a 2008 KK sport. I am wondering if there is anywhere you can buy the infinity sound system components that come in the limited. I am mainly interested in the sub-woofer since the box fits so nicely and out of the way. I looked at crutchfield, quadratec and mtx thunderform but can't seem to find an after-market box that is made specifically for the KK. Any suggestions would be appreciated. Thanks.
