11. This back panel would serve as the foundation to hold the amplifier in place.

12. The Pioneer amplifier was pre-fitted before it was bolted down.

13. With everything being pressure fitted, it was checked one last time before tearing it all down to complete the final install.

14. For sound deadening, the trunk received some Accumat material.

15. With the speaker box out, you can see how complicated this speaker box was.

16. The kick panel area would be receiving the Pioneer mid range components.

17. The components were mounted on MDF board, which will allow them to bolt up in the kick panel area.

18. The rear fill audio was mounted to the rear window panels.

19. The marine carpet was the first part to be laid out in the final assembly.

20. The speaker box was pushed all the way back to allow the face panels to be placed in. The face panels complemented the audio equipment and gave the trunk panels some character.

21. When doing a Lowrider trunk, the hydraulics and the audio go hand-in-hand and now that the audio is dialed in, it is time to plan out the mounting of the hydraulics.

22. Even though it might have looked as if there was lots of room, trunk space will become limited if the hydraulics are not planned out right. As you can see we went from four batteries to three in order to gain trunk real estate.

23. After measurements and a day worth of planning, the hydraulic rack was welded together.

24. With the rack bolted in place, the hydraulics were installed to allow the car’s trunk to come to life.

25. To power the hydraulic system, we installed 3 Optima yellow top batteries in a custom-built billet tray.

26. This trunk was ready to rock, as it featured Pioneer’s latest audio and a custom hydraulic set up that will make you look twice and allow room for luggage in case they throw you out of the house!
