I've tried much luck with installing speakers on the doors, but only to no avail. Most of the woofers out there are just too big for the doors to handle. Anyhow, there are these woofers made my Infinity, called Uniplanes, and I plan to install them on the side of the doors, along with the tweeters near the door handle. Do you guys think this is a good idea? If not, where would be the best place to place the speakers/tweeter and how would I do that? Thanks in advance.
