Buick Skylark - Primo Subwoofer Install
We previously covered the frontstage. Now we move to the rear and the subwoofer system. The goal was to conserve as much space as possible. The depth of the sidewalls, shape of the back wall and the locations of the amps were dictated by that. Given that this is an old car, the trunk is basically all bare metal, with no trim or anything, so that had to be built.
The trunk with all the grilles in place, furnished in grey trunk liner. Simplicity in Sound pushed the front wall back as far as possible and built two simple structures that hide the metal plates that the trunk hinges attach to.
With the front and floor grilles removed you can see three Morel Primo 10" subs firing backwards, and three Mosconi Gladen Audio amps on the floor. An XL150C4 sends 150 watts to the mid/tweet combo in each kick, and 150 watts to each rear component set, a RS150C2 powers the midbass drivers with 150 watts a piece, and a SPL 1800C1 sends a whopping 1800 watts or so to the three Morel subs.
Everything is trimmed in a dark red vinyl that matches the exterior of the car and all the gear is flush mounted.
The customer also asked SiS to provide some type of lighting so he can see what is in the trunk in the dark. There are two hyper white LED floodlights from Oznium.com sunk into the panel. They are operated via a remote control fob attached to the key chain.
The two covers on the side walls conceal a storage compartment and space for a battery. Two EFX DELTA Dclamp terminals were used.
Here's the main foundational board bolted to the floor of the trunk. It provides a solid and flat mounting surface for everything else.
Then two extra platforms were bolted to the left and right sides, they would anchor the two compartments.
Next, the 2 cubic foot sealed enclosoure was constructed for the three subs. It has a sloping top and takes advantage of as much air space as possible. The front is covered in red vinyl, and inside it's stuffed with Blackhole STUFF. The box was secured to the car using six threaded inserts going into the foundational board which allows six bolts to secure the box. Additional bolts were used to secure the sides to the floor.
Here is the subwoofer trim panel before and after vinyl application, along with the other pieces for the trunk.

Simplicity in Sound, Bing Xu: "I have to say that I am utterly blown away by the Virtus 693 3-way set. I heard them at CES in (Morel America COO) Casey Thorson's car and was mighty impressed, so I had high expectations, but I am still really amazed at how they performed. Right out of the box, no adjustment of anything, they were warm, smooth, natural, with very nice impact and detail. The last two things were perhaps the most noted improvements over the older Morel drivers. The car images okay, center is rock solid with the center channel, height is dash level, a little rainbowing left and right, but overall tonality is excellent.
"I also had the same positve impression of the Primo subs. They provide an outstanding amount of smooth, deep and fast subbass, blend with the music well, and most surprisingly, the car has truly nice subbass output even with the top down.
"Overall, i cannot praise this new generation of Morel products enough, expect to see more Virtus and Primo installs from me in the near future, along with the other redesigned Morel lines higher up in the food chain. "
As you can see in our archives that's exactly what SiS has done.
