NOTES ON INSTALLING AND USING YOUR NEW WAKETUNES SPEAKERS
For best performance, provide 100W-RMS at 4 Ohm to each speaker
Always remove the wires from the binding posts before removing speakers
Speakers can be easily removed by loosening the locking set screw, removing the detent
pin and lowering the speaker
Speakers can be pointed to the rider or the front of the boat by loosening the locking set
screw, removing the detent pin and rotating the speaker
Regularly check all hardware to make sure it is tight
Although the speakers are weather resistant and designed for outdoors use, do not spray
directly into the grill with high-pressure water
Remove speakers for trailering to prevent bugs and road debris that need to be cleaned
Handle the speakers with care as the aluminum enclosures can be damaged if dropped

Assembly Instructions
STEP 1: Attach the Collar Bracket (Item 1) to the tower using M8x25 tower clamp bolts (Item 3)
and the Delrin Collar Inserts (Item 2) that matches your size tower (2-1/2” are provided for Monster
Towers and a universal kit with 1-1/2”, 1-5/8”, 1-3/4”, 1-7/8”, 2” and 2-1/4” are provided for other
towers). Tighten to 20 ft-lbs.
STEP 2: Loosen the Item 4 Mounting Post Bolts and rotate the Item 1 Mounting Post so the hole
in the post aligns with the centerline of the boat. Tighten the Item 4 bolts to hold the post from
rotating.
STEP 3: Attached the Item 5 Speaker Bridge to the Mounting Post and insert the Item 6 Detent Pin
through the Item 5 Speaker Bridge and Mounting Post. The button on the end of the Detent Pin
must be pressed in when inserting or removing the Detent Pin. This is how the speakers are
installed and removed from the tower.
STEP 4: Tighten the Item 7 Locking Set Screw using the Item 8 T-Handle Hex Wrench. This is not
required for smooth water or if double-up’s are not routinely performed. For rougher water the
Locking Set Screw adds an effective stiffening of the speakers to the clamp.
STEP 5: You can aim the speakers by rotating the Mounting Post. We recommend aiming each
speaker 10-15 degrees to the outside of the wake corresponding to the side of the tower the
speaker is mounted on. This will eliminate any phasing or imaging of the speakers and provide a
more balanced sound to the rider as they move across the wake. Once positioned, tighten the
mounting post bolts to 20 ft-lbs.
STEP 6: Attached your amp wires to the binding post and go wakeboarding!

Wiring Instructions and Amplifier Considerations
We recommend you use 16 to 18 gage wiring between the
speakers and amplifier. Consult your tower installation manual
or provider for instructions on running wire inside your tower.
We recommend covering the wiring with 3/8” or 1/2” wiring loom
and electrical tape as shown for a professional, watertight
appearance.
The most common way to wire a boat with tower speakers is
with the front speaker or front pre-amp outputs of the stereo
driving all speakers in the boat. The rear speaker or rear pre-
amp outputs are then used for the tower speakers. This allows
the fader to control the volume from inside to behind the boat.
A four-channel amplifier in the boat is typical with two channels driving the boat speakers and two
channels driving the tower speakers. The next level is to have separate amplifiers for the boat
and for the tower speakers. We recommend supplying 100 RMS at 4 Ohms to each speaker. The
peak power of an amplifier is what is advertised, but is also often misleading. The RMS at a
specific Ohm Load is the real working power of the amplifier. It is generally agreed by audiophiles
that supplying too much power to speakers is far better than under powering the speakers. If
there is too much power the signal “clips off” and the speakers let you know with no damage.
With too little power, you send lots of distortion to the speaker, which causes speaker damage.
It’s far better to “over amp” the speakers and not turn it up all the way than “under amp” them and
send up damaging distortion.
Most amps have a Bass boost or filter that you can use to remove or add Bass. Turn this off or
put on the lowest setting to remove as much Bass as possible to the tower speakers. If your amp
has a High Pass Filter turn it to the highest frequency that sounds good to filter out as much Bass
as possible. The Bass uses the majority of the amplifier power with sound that will not reach the
rider. Mostly high frequency and upper mid-Bass will be audible at 65’-80’ behind the boat over
engine, water and wind noise.
For learning more about tower audio, we highly encourage you to visit the “Boats and
Accessories” discussion boards at www.Wakeboarder.com and www.WakeWorld.com. We also
support a website at www.diyTower.com that has a wealth of information on tower audio.
