here's the pics he sent me; i haven't taken any of my own. the enclosures are fiberglass and were custom layed in his car; they fit the exact contours of the rear firewall. he insists that at 5'-10" tall, he drove with these in his car for two years. i personally don't think someone that tall would be comfortable, which is why i dropped the price from the $400 i paid to the $250 i'm asking.
