bracket. Please select the correct insert size
according to the insert selection guide on page 3.

through wire hole. Place top bracket on top of the
bar above the enclosure. Start to thread the bracket
screws into bracket from inside the enclosure.
Tighten front and back screws evenly, make sure to
tighten until bracket holds tight and the enclosure
does not move.
Step 5
– Connect speaker wire to the input on the
speaker, making sure to keep the polarity correct.
Place woofer into the enclosure with the badge
closest to the top. Make sure to tuck the wires

opening. Screw in the 4 speaker bolts, make sure to
tighten the bolts fully.
NOTE: If bolts are removed after installation,
threadlock must be re-applied.
