Wow.. These videos are so underrated, as well as his other videos..
I subscribed, just for the attention to details and the calm voice!
In my '83, I just bypassed the (assumed) dead paper cones in the rear, and put in two 2-way 6.5" speaker boxes, I seldom carry anything more than detailing stuff and my Celica Supra flag in there anyways..
I try to play 80's music as often as possible, Yello is good!
