Prevost Motorcoach

With the significant depreciation of a luxury motorcoach it was extremely cost efficient for Earmark to modernize this several-year-old model.

In the process we added electronic and entertainment amenities far beyond what can be found as factory equipment on today’s most lavish motorcoaches.

Located directly in front of the driver, we installed an Alpine IVAD901 that displays navigational information as well as giving the driver individual viewing and listening options. Directly to the right of the console is a Kenwood Sirius satellite receiver that provides 120 channels of satellite radio throughout all areas inside and outside.

Kenwood Sirius controller housed in a custom dyed panel.

Located directly above the driver on both sides is a pair of Boston Acoustics speakers. This zone is dedicated to the driver and controlled by the Alpine multimedia source unit.

Directly above the driver is the audio/video control center. The existing VCR was removed in favor of upgrading to a DVD player. This was all integrated into the existing Bose audio system. The concealed DVD player is controlled via an IR repeater system with access throughout the entire Coach.
Within the audio/video control center is an RF transmitter providing video signal to the kitchen and bathroom LCD’s.
On the driver side of the living area a couch conceals a subwoofer amplifier that was added to give the front of the motorcoach more low-end response. This was integrated into the Bose audio system and supplemented the existing
Bose subwoofer.
With the couch cushion removed the amplifier is exposed. This JL Audio monoblock amplifier provides power to a Boston Acoustics Pro Series subwoofer located in the bottom shelf of the kitchen cabinet.
Concealed in the kitchen cabinet the subwoofer radiates through vents under the cabinet door.

This front to back view of the motorcoach provides prospective of the floorplan. Notice the inconspicuous corner-mounted LCD screen just above the dining table.
This 8.4” LCD monitor is mounted inside a custom housing that’s protected by a lightly smoked acrylic front panel. This is one of several monitors that receive a wireless video signal from the cab’s audio/video control center.
For the purpose of access to entertainment wherever you go, this 7” flat LCD monitor was flush-mounted directly above the sink in the bathroom. The monitor is protected by a smoked acrylic front panel. This LCD also receives a wireless video signal from the cab’s audio/video control center. Both the dinette and bathroom LCD’s disappear behind the acrylic panels when inactive. When active the acrylic cover panels allow for full brightness while cutting down on daytime glare.
The motorcoach rear bedroom.
The ceiling area of the bedroom now house three pair of Boston Acoustics speakers. The speaker grills were dyed to match the surrounding appointments. Two pair of speakers are for theater sound while one pair is part of the whole-coach audio system.
The existing TV in the bedroom displays video from the DVD player, satellite TV, and local TV broadcast. The TV also functions as a demodulator for the multiplexed signals emanating from the cab’s control center. The TV output is connected to the CD receiver’s auxiliary input.
Directly above the bed is a mirrored wall that contains a storage cabinet. This provided an ideal location for the bedroom’s audio components.
This cabinet received modifications to fit an Alpine CD receiver, 6-disc CD/MP3 changer and a 6-channel JL Audio amplifier. The amplifier drives the Boston Acoustics speakers in the ceiling and two 10-inch JL Audio subwoofers.
The JL Audio subwoofers are concealed below a motorized panel located in the base of the bed.
The two woofers are loaded in downfiring enclosures located on both sides of the house safe. These woofers radiate through custom vents that we introduced on the underside of the bed’s baseboard.
This cargo bay hatch conceals the exterior audio/video entertainment center.
We designed and hand built the exterior entertainment system cabinet to be very user friendly even though it serves multiple, complex functions. Incorporated in this unit are 3 storage drawers on the left side of the cabinet. The Phillips 32-inch LCD is protected by an acrylic front panel. The center panel under the LCD is the port for a JL Audio subwoofer enclosure that is concealed at the rear of the cabinet.
An IR target is located just above the LCD. The target is normally concealed by the cover panel. The target allows full control of the interior audio/video components.
On the left side and underneath the LCD a custom panel with a sliding door contains a 110 volt outlet and gameport. The panel also houses a line-level bass control for the JL Audio monoblock amplifier.
On the opposite side of the cabinet’s lower section is another panel that houses a second 110 volt outlet plus audio jacks for a pair of outdoor Bose speakers. These outdoor speakers and their pedestals are normally stored away in one of the cargo bays. Long extension cables allow the Bose speakers to be placed up to fifty feet away.
All of the other cabinets within the undercarriage were recovered in
matching laminate as part of our restoration. Many of the existing cabinets had chipped faces so we added protective aluminum channels to the bottom edge.
All audio/video components located throughout the entire coach are controlled via this full color Pronto Pro NG remote control. We programmed screen icons and multi-function macros to maximize convenience and ease of operation.
