Sadly the nakamichi's are rediculously expensive personally. I've always been a fan of having it work perfectly before the looks, so I've never cared about if it matches or not. That being said, I've got a kenwood, its about 5 years old, but works great and has survived 2 e30's haha.
My speakers are long gone... I've got some kappa perfect's sitting in my room waiting to go in the e30 soon as I'm done w/ the motor work.
