Thanks for the warm welcome guys
I've actually ordered a couple things from seoulfulracing before - some small interior pieces, but I'm not as huge into the KDM thing as some tib owners are.
In 2005, Hyundai went from Infinity systems to Kenwood systems, which means no factory sub in my car, which explains my desire for the basslink. The aux-in is up in the air - right now I'm leaning more toward just buying a new headunit that's already ipod ready.
