One of the most important additions to our Project 2001 Nissan Sentra SE will be the audio/video system, featuring matched Sony Xplod components. We chose to have the work performed by the IASCA award-winning pros at Advantage Audio & Alarm (Brea, California) whose custom installations we’ve featured several times in both Euro and Lowrider Magazines.

We started by discussing exactly what the system would involve with Advantage owner Ron Valentine and ace installer Jamie Fifield. “You should first envision the entire installation in your mind and put it down on paper before you begin,” said Jamie. Once that was determined, we knew that te first step in the process would be adding a custom spare tire well bass speaker enclosure. We followed Jamie from the beginning as he made a really cool wood and fiberglass box with a bowl-shaped center section for three 10-inch Sony XS-L1035 Xplod subwoofers.

No special tools are required, but you will need the following tools and supplies: an electric sabre saw and wood-cutting blade, electric drill and bits, 4×8-foot sheet of 3/4-inch MDF (medium density fiberboard), assorted wood screws, tube of Titebond II wood glue, can of Touch ‘n Foam expanding insulating sealant, gallon of fiberglass resin and liquid hardener, one gallon of body filler and cream hardener, plastic paddle, package of fiberglass mat, 3-foot piece of black speaker cloth, sanding block, package of assorted sandpaper, half-round file, several cheap 2-inch brushes, several large cardboard mixing buckets and several pair of sheer vinyl gloves.

Jamie took the box to the point where it’s ready for the body shop to add the final coat of filler and paint it. The box could also be finished in fabric or vinyl if desired. The next step in the installation will be running the Stinger wiring, connectors, fuse blocks and terminals, but that’s the next issue. For now, follow the photos as we show you how to help your subwoofers deliver the maximum boom for the buck with a bass box. *
