Enclosure Assembly:

First, set the enclosure parts out on a flat level surface and ensure that all pieces are free of dust and debris.
With the bottom panel lying flat, glue the internal walls in place making sure the front edges are flush with the front of the bottom panel.
Next, glue the front baffle in place assuring all edges line up and are flush, and the internal walls fit into their dados. Clamp in place and allow glue to dry per glue manufacturers recommendations.
Once glue is dry, glue in side and rear panels as shown below. Ensuring all outside edges are flush, clamp and let glue dry as per glue manufacturer’s recommendations.
Once the glue is dry you can install the crossover boards into each speaker cavity. We recommend placing them in the center of the bottom panel inside each left/right enclosure. Ensure that each foam-wrapped speaker wire lead can reach the holes in the baffle. The red (+) and black (-) wires go to the woofer, the blue (+) and black (-) wires go to the tweeter. The crossovers can be secured with the included wood screws. BE CAREFUL NOT TO OVERTIGHTEN SCREWS.
Next, remove the 4-conductor speaker wire harness from the amplifier package (#1 in the amplifier wiring diagram) and feed the two +/- conductors into each speaker chamber through the small holes in the internal walls. Leave enough slack in the center cavity to be able to plug the harness into the amplifier, roughly 8-10″.
Next, cut the small white connector off of the red and black wires on each crossover and strip the wires back roughly 1/4″.
Using the wiring diagram below, solder the left and right channels of the wire harness to each crossover observing polarity. Use heat shrink to cover the soldered connections.
Use the hot glue gun to seal up the through-holes in the internal walls.
Once this is complete you are ready to glue the top panel on the enclosure. Clamp it up and allow it to dry per the glue manufacturers recommendations.
This is a good point to apply your chosen finish on the enclosures. Sand all surfaces and make sure all seams are sanded smooth to ensure a quality final product.
Final Assembly
Once you have your speakers finished you are ready for final assembly. First, wire up the woofers and tweeters to the installed crossovers. The red/black wires go to the woofers and the blue/black wires go to the tweeters. The colored wires are positive, be sure to observe polarity.
Install woofers and tweeters by hand using a #2 Phillips screw driver.
Install ports in the rear of the enclosure. These simply press-fit into place.
Next, put together the amplifier, battery board and faceplate assembly according to the wiring guide that comes with the amplifier.
Connect the four conductor speaker lead you previously installed in the enclosure to the amplifier plate assembly and install the assembly into the rear of the enclosure.
Plug in the included power supply to the rear panel power plug, this will activate the speaker battery board. You are now ready to enjoy your finished MKBoom!
