1. If needed for daisy chaining
drill speaker base and install 
second liquid-tight strain relief
(not included).

2. Attach inground/security
brackets to speaker base
using stainless-steel bolts.
 

5. Attach signal wire to wire
leads. Use wire nuts pro-
vided. For added water
proofing, grease caps 
are recommended.

3. Thread signal wire thru 
liquid-tight strain relief 
and tighten seal.
 

 

4. Place speaker base into 
hole in ground with the top
rim of the base at ground
level. Back-fill dirt in to 
hole, packing the dirt 
firmly. For added security, 
cement security brackets
into ground. 

6. Set speaker enclosure on
speaker base. Use tamper-
resistant stainless-steel 
screws to attach 
speaker to base (driver
tip and screws provided).

7. Done!

To enhance bass performance, 
remove port cover on the 
underside of speaker enclosure. 

Warning: Removing the cover 
will expose internal components 
to humidity and other potentially 
corrosive elements.
