How to Build a 6x9 Speaker Boxby Nichole Liandi
A 6x9 car speaker is a versatile car audio machine. The cone is large enough for solid bass, while the tweeters provide clear highs. If you have a vehicle that lacks space for speaker installations or upgrades, adding 6x9 speakers -- mounted in boxes -- will step up your speaker performance. You can build sturdy and serviceable speaker boxes with basic tools and materials.
With a circular saw, cut two rectangular pieces of 3/4-inch MDF to 12x8 inches each. These are the front and back panels of the speaker box.
With a circular saw, cut two rectangular pieces of 3/4-inch MDF to 12x6 inches each. These are the top and bottom panels of the speaker box.
With a circular saw, cut two rectangular pieces of 3/4-inch MDF to 6-1/2x6 inches each. These are the end panels of the speaker box.
Assemble the top, bottom and end pieces together to form a hollow square, with the top and bottom pieces overlapping the 3/4-inch sides of the end pieces. Connect the pieces together with 1-1/2-inch wood screws, spaced 2 inches apart.
Cut an opening in the front panel for your speaker. Use the speaker as a template for the opening, and cut the opening with a jig saw or keyhole saw.
Attach the front panel of the box onto the hollow square you built in Step 4. Attach it with wood screws, spaced every 2 inches.
Attach the speaker to the opening in the front panel with the screws supplied with the speaker. Make sure the magnet side of the speaker is in the box.
Solder the ends of an 8-foot length of speaker wire to the speaker's terminals.
Drill a small hole near the bottom of the back panel, about 1 inch from the edge. Use a drill bit that's slightly larger than the thickness of the speaker wire. Feed the end of the speaker wire through the hole and pull the wire through.
Attach the back panel to the speaker box with wood screws, spaced every 2 inches.
Repeat all the steps above to make a second box.
