Modification to accessories that mount overhead near the front of the roll cage

require modification. Contact Hoppe customer service for questions.
2.2 Audio Equipment Details:
Your Audio Mini off-road sound system is powered by using
their marine series audio equipment. This equipment is designed to function in all
weather conditions with an IPX6 water resistance (powerful water jet) rating. The stereo
is specifically engineered to provide excellent sound quality and volume in an open air
enviroment so you can enjoy your music on the go.
To learn more details about your stereo system, you can access product information and
manuals for the stereo equipment here:
KMC2 receiver: https://www.kicker.com/kmc2
Speakers: https://www.kicker.com/41KM604W
You can feel free to crank up the volume without much worry of harming your system.
However, it is wise to use a little common sense. If you hear any distortion, back off a
little.
Use the equalizer settings in your KMC2 receiver to adjust the settings to your
preferences.

2.3 Warranty:
Your Audio Mini comes equipped with a 1 year limited warranty covering the light, the
stereo equipment, and the fiberglass enclosure. The date of warranty coverage will be
determined by the registration date of the warranty card or online warranty registration.
http://www.motortrike.com/TrikeAccWarranty.aspx
If the warranty is not registered with Hoppe, the warranty period will begin when the
Audio Mini was shipped from Hoppe's factory.
2.4 Care and Maintenance:
Your off-road sound system does not require any maintenance other than an occasional
cleaning. To clean your audio system, simply hose off or power wash from a distance. If
needed, use a mild automotive soap and sponge or brush. Use common sense. Do not use
a high pressure power washer up close where it could cut, scar, or force water beyond the
design intent of the enclosure, light, or stereo equipment.
There is an inline fuse, close to the end of the chassis harness where it connects to the
battery. It can be accessed by pulling the cap off of the fuse holder. See Figure 1.
Figure 1: Fuse location.
Fuse 1: 15 amp mini fuse for light / radio receiver power.
There is also a 40 amp capacity skirted mini ignition relay built into the chassis harness
next to the inline fuse. See Figure 2.

2.5 Warnings:
This off-road system adds up to 25 lbs. to your vehicle and is located up high on the roll
cage. This increases the vehicle’s center of gravity and changes the vehicle dynamics and
handling characteristics. Use extra caution as you learn the driving characteristics of your
vehicle with your new off-road sound system installed. High speed cornering, off camber
or side hill, acceleration, and braking performance will be negatively impacted by the
weight of the sound system.
Do not listen to your stereo at an uncomfortable volume for extended periods of time.
Potential hearing loss may result.

SECTION 4 – Installation
1. Remove the factory bolts from the driver’s side of the front cross member. The
bolts will not be reused. Note: If you have a roof installed, remove the front
mounting bolts to gain access to the cross member bolts. See Figure 3 and
Figure 4.
Figure 3: Remove the factory cross member bolts.
Figure 4: Factory roof mounting bolt.
2. Place the bracket on the inside of the cross member. Use the supplied M10 bolts,
and loosely tighten them to allow for adjustment of the Audio Mini placement.
Verify correct orientation of the mounting bracket. See Figure 5.

3. Repeat Steps 1 and 2 for the passenger side bracket. Note: Reinstall your roof
fasteners after this step.
4. Using an assistant, hang the Audio Mini off-road sound system on the brackets
using the supplied ¼”-20 bolts and washers (loosely tightened). Note: The sound
system weighs up to 25 lbs. Since you will have to lift overhead and bolt each
end, it is helpful to have an assistant for this step. See Figure 6 and Figure 7.
