I'm also in the process of upgrading the equipment in my 65. The car came with a Custom Autosound AM/FM/Casette, but I'm adding the Ken Harrison Enterprises Upgrade Pioneer Coaxial Dual Dash Speakers (front & back), which I purchased
here. I'm also adding the
amplified spare tire subwoofer (available from the same link as the Pioneer speakers) and a
FM modulated Sony 10 CD changer with MP3 support.
I'll make another post when I have everything finished and let you guys know how it sounds.
