I am in the process of upgrading my audio system in my 82. I have decided to replace the factory head unit, speakers, two amps, add a pair of 6x9s in the storage bins, and, and a pair of 10 inch subs. I am wondering if there is a easy way to mount subs in first gen, aside of building a speaker box myself.

 

I'd put the 10s in the storage bins, 5.25 or 6.5 in the doors and some tweeters firing up at the windshield.
