| Harmon Kardon speakers ?
I have a 2004 cooper with the HK system. I would like to replace the head unit with one that does not have a built in amp. I know the factory amp is propritary but my question is are the speakers also ?
I would like to install the head unit with an aftermarket amp and keep the HK speakers..
If anyone knows the answer it would be great I asked one install place and they think the speakers are standard but I don't think they really know. |
