The description of Audio System Design
One of the cheapest and easiest to upgrade your car audio system is the DIY subwoofer. Subwoofer A enhances the sound of your system by increasing the bass and adding depth to other flat sounding systems. Your own installation is simple and will have your pumping system in no time.
For this project, you should have 3/4-inch-thick medium - density fiberboard, PVA glue, screws, clamps, silicones, carpets, a terminal cup (which is a plastic cup with a terminal to connect the speaker cable to the speakers), speaker wire, and subwoofer. For tools, you will need tape measure, pencil, screwdriver, saw, drill, and soldering iron.
There are several brands of subwoofer speakers in the market, catering for all budgets. Common speaker sizes are 10, 12, 15, and 18 inches. Measure space to adjust the box to make sure you do not buy a speaker that is too big. Plan to build boxes around the speakers you buy and the space available.
The best place to install the box will usually be in the trunk or trunk of your car. An efficient design is a rectangular box with surface mounted speakers scooped back at an angle. The flat rear surface of the box should sit into the back of your rear seat, leaving the speakers facing out into the trunk area.
Measure the front face of the size box using the measurement you take, leaving at least a few inches above and below the outer diameter of the speaker.
Cut the remaining three sides of the box for size.
Use the speaker as a template to create an opening for the subwoofer, marking the borehole for screw mounting.
Use the jigsaw to cut the hole for the speaker, and predrill the mounting screw hole to a size slightly smaller than the actual screw.
Depending on where you intend to route the speaker cable, predrill and cut holes on the back or side of the panel the same diameter as the terminal cup.
Fit the terminal cup, use silicone to cover and secure it in place.
Glue and then screw the front, rear panel, bottom, and sides of the box together. (Do not install speakers yet.)
Seal all the joints with silicone to create an airtight box.
Cover each panel with glue and apply the carpet, pull it tight and spread it on the back, sides, and back - panel surfaces.
Cut the carpet into segmented parts for the speaker holes rather than cutting the holes for a more tidy finish. Fold segmented parts and glue to the inside of the box.
Apply glue and carpet to the front.
Run the cables from the speakers through the holes in the front panel of the box and solder the cables to the back of the speaker terminal and terminal terminal terminal terminals. Make sure you join negative to positive and negative to positive.
Fit speakers in place and tighten with screws.
Place the speaker cover on the speakers and secure it in place in your car.
Connect the cable from your sound system or from your amp if you have one - to the subwoofer. You are ready to rock.
