UT65B: How To Set Up & Use

Introduction

The Rockville UT65B is a set of 6.5” marine-grade wakeboard speakers designed for UTVs, ATVs, boats, and off-road vehicles. These speakers come with 360° swivel brackets for precise positioning and secure mounting options on roll bars or wakeboard towers. This guide will walk you through installation, mounting, and wiring to an amplifier.

What's Included

• Two UT65B speakers
• Two non-slip rubber pads (for grip)
• Rubber slits (for various bar sizes)
• Four 1.75” rings and four 2” rings (for mounting)
• Four washers, four nuts, and four screws
• Allen key (for installation)

Step-by-Step Setup

1. Adjusting the Swivel Bracket

• Loosen the two outer screws inside the bracket.
• Loosen the middle screw to adjust the bracket's position.
• Rotate the swivel bracket until the holes align with the speaker.
• Secure the bracket back into place by tightening the screws.

2. Attaching the Rubber Pads

• Remove the adhesive backing from a rubber pad.
• Stick it onto the top of the swivel bracket to prevent slipping.

3. Mounting the Speakers to a Bar

• Choose the correct ring size for your bar (1.75” or 2”).
• Insert a rubber slit inside each ring for a secure grip.
• Stack multiple rubber strips if needed for a tighter fit.
• Place the rings onto the bar at the desired mounting position.
• Position the speaker between the two rings.
• Slide the rings onto the bracket, aligning their holes with the bracket holes.

4. Securing the Speakers to the Bar

• Take two screws and insert them through the washers.
• Feed the screws through the bracket holes.
• Secure them by tightening two nuts onto the screws.
• The grooves on the back of the rings will hold the nuts in place while tightening.

Connecting the Speakers to an Amplifier

5. Parallel Wiring for a 4-Channel Marine Amplifier (ATOM P20)

• Since the UT65B speakers are 4-ohm, you can wire two speakers per channel in parallel.
• Connecting the Speakers:
  • Take speaker wire and connect it to the positive and negative push terminals on the back of the speakers.
  • Use a screwdriver to loosen the terminals on the amplifier.
  • Insert the speaker wires into the positive and negative terminals of channels 1 and 2.
  • Tighten the amplifier terminals to lock the wires in place.

Testing the Speakers

• Connect your phone or music source to the amplifier.
• Power on the system and play music to test the audio.
• Adjust the position of the speakers using the 360° swivel brackets for optimal sound direction.

Conclusion

The Rockville UT65B offers powerful, marine-grade audio performance with secure mounting and flexible positioning for UTVs, ATVs, boats, and wakeboard towers. Once installed and connected to an amplifier, these speakers provide clear, powerful sound for outdoor adventures.
