How to Make DIY Powered Car Subwoofer Box

  • Hey what is going on YouTube, make your music listening more enjoyable while driving around in your car, van, truck or even on a boat! If you have the time and skills you can make your own active subwoofer enclosure for your car.
    Yes, you read it right, has built-in subwoofer amplifier board mono channel. There are 10 steps in this tutorial so let's get this thing kicking:
    STEP 1 - SUBWOOFER ENCLOSURE DESIGN AND CALCULATION
    I used a free web 3D design software called TinkerCad and you might as well use the design for your reference. Here's the link of the project - www.tinkercad.com/things/8JlHfT78QPf
    Enclosure volume calculator - www.hometheatershack.com/forums/enclosure-volume-calculator/
    STEP 2 - UNBOXING OF MAIN COMPONENTS
    I purchased a subwoofer plate amplifier on Aliexpress.
    Subwoofer driver is a JBL CS1214 12" 4 Ohms Single Voice Coil car subwoofer, purchased on Lazada (Philippines).
    STEP 3 - ENCLOSURE BUILDING
    In this step, carpentry skills become very useful and I admit I need to practice more doing carpentry stuff. ^_^
    A 3/4" (0.75") MDF board is the coolest choice over marine plywood. Stikwel wood glue as adhesive. Used a plunge or palm router in cutting the subwoofer hole. Hole saw for cutting smaller holes. And a bunch of clamps for holding the project while gluing and screwing. I prefer using jigsaw in cutting the board because I suck at cutting with circular saws.
    STEP 4 - INSTALLATION PORT TUBE AND BRACES
    JBL subwoofer box recommended a 4" port tube in a 1.75cuft enclosure but I made this slightly smaller. I used a 12" long with a diameter of 3" PVC pipe for port tube venting in this 1.65cuft enclosure.
    STEP 5 - COMPLETE THE BOX BUILDING
    Cut an angled edge MDF board for the back cover wedge shaped enclosure. Screw everything down and don't forget to flush drill holes. Protruding metal screw heads are not cool.
    STEP 6 - CUT HOLE FOR AMPLIFIER PLATE
    I enclosed the amplifier plate board using scrap MDF and plywood. Must enclose to prevent tiny electronic components on board get damage by strong bass air pressure inside enclosure.
    STEP 7 - DRILL HOLES FOR SUBWOOFER DRIVER BOLTS
    Secured the driver with 5mm stainless steel T-nuts. Bolts are Allen Hex, back steel.
    STEP 8 - CARPETING
    A 1 meter x 6 feet black speaker carpet and adhesive is a contact rubber cement. Box cutter with extra blades in cutting them into seamless look.
    STEP 9 - SOLDER WIRE TO DRIVER AND BOLT DOWN
    Original plan was to use Allen Hex screws in fastening the subwoofer plate. In the video, you see I used an ordinary black wood screws. Bolted down the subwoofer in this step and tighten good.
    STEP 10 - VEHICLE WIRE WORKS
    Must use an 8 AWG gauge automotive wire for power. Secured the power wiring with a 60A car audio fuse holder. Remote cable is a 16 AWG gauge wire with color blue soldered to head unit REMOTE PWR tab. Wrapped the cables using a cheap plastic spiral wrap. This tidy up eveything, aesthetic looks and added a marging of safety.
    FINAL STEP - TIME FOR SOME BASS TEST!
    Macbook Pro attached to head unit AUX playing the following tracks from YouTube:
