01. The inner cargo walls were stripped and these metal brackets were bolted in. 02. These crossbars were then welded in to support the amp. 03. A Medium Density Fibre board was secured to the rack.

Part 2, Finishing Up
Here is what was involved:
installment, though this accounts for the vast majority – ate up 900 hours of skilled labour, and provides 3,000W of power.
Here, we’ll show you how the crew tackled the rear door panels, inserting an amp rack on either side of the cargo area along with install-ing twin monitors in the each of the rear side windows, not to mention the huge enclosure / amp rack / entertainment block now taking up residence in the cargo area.

04. Test-fitting Alpine’s tiny but deadly PDX2.150 amplifier to the board. Also, the plastic panel was trimmed to expose the amp. 05. The area was then masked off with some fabric to fabricate the panel with fibreglass. 06. All masked off, it’s ready for fibreglass and Rage Gold body filler. 07. Some more protection for the floor and the first layer of fibreglass laid down. 08. With the panel sanded and ready for paint, one more test-fit is made to ensure the job doesn’t need to be done twice. 09. All done, the complete job looks flawless. 10. The Alpine PKG-1000 monitors are taken out of their flip-down overhead cases and rigged up to ensure they work. 11. Fabricating the monitor trim housing. 12. The trim panels all done, ready to be put into the Medium Density Fibre board brackets in the windows.

13. Plugged into their new housings, the monitors work without hiccups. 14. The box needed to be mounted in the cargo area. The team drilled into the floor and mounted these rubber-isolated mounts for the enclosure, which is to be elevated. 15. The frame for the box needed to be fabbed up, so the metal was cut using a chop saw and welded together using a MIG welder. 16. The speaker and woofer box starting to take shape. The biggest pieces are screwed and glued together here. 17. Box is downwardly vented, making use of loading the frequencies into the floor for an overall output gain. Note vent walls are rounded for unobstructed air flow. 18. The woofer rings are now secured and the main subwoofer box is complete. 19. The Alpine guys are big into measuring and checking double and triple to prevent costly mistakes, so the enclosure was thrown into the truck and products put in. 20. The box corners were fibreglassed to reduce the number of hard angles in the enclosure, thus helping to lessen the amount of standing waves in the box. This improves overall output and accuracy. 21. Metal shelves were made and bolted in for the amplifiers.

22. This being more than just a sub box, the ‘skeletons’ (AKA amplifier shelves and component speaker mounts) had to be added on. 23. With all these additions, the crew had to test-fit the behemoth once more. Note the flip-out Alpine PKG-1000 in the center of the box. 24. Steve Brown is applying a fin-ishing coat of putty. 25. Trim / accenting rings are attached to each driver mounting location. 26. Masking off the rear door for an Alpine sign fabrication. 27. First layers of fibreglass being laid down. 28. One last test-fit before the enclosure / rack goes into the paint booth. 29. Final product of the Alpine signature on the inside of the rear door. 30. Final product of all the hard work. Good job guys; this H3 certainly gets heard!
