Im 6'2" and own the 89 yota std cab pickup, and all I did was Kenwood 5" eXceleons in the doors/4" Audio Bahns in the dash and 2 8" Rockford Fosgate Stage1 Punch woofers built in slanted boxes that bolt through the back of the cab. Ran all the wires under the interior plastic and through the rubber blockout on the firewall to hide all the wires. Used a rockford amp and hard mounted it to the back of the cab as well with self tapping screws. I couldnt be happier with Bass/Mid and Highs. Whole system cost less then $300 (Thats Front Speakers/Door Speakers/Amp/Woofers/Box/Wiring Harness) AND from Crutchfield!
