There are many benefits to an efficient audio system, particularly in a wakeboard boat. And this system maximized efficiency in key areas such as voltage management, amplifier efficiency, subwoofer design and system tuning. To date this is the most coherent sounding HLCD system I have heard. Its also an extremely dynamic system which I believe is appreciated much more due to the fact that its a very linear system, especially given the use of HLCDs.

This Alpine marine source unit has excellent iPod control and functionality. The ABS mounting bezel was moderately textured and dyed (flat black over black) to provide an appearance of vinyl.
Display remotes underdash and on the transom.

Plug terminated in pocket for iPod storage.

WetSounds equalizer suspended underdash via an HDPE panel which also serves to strain relieve all cables.

The mic is stored in the right hand compartment.

Amplifier rack covered in rubber-backed marine-grade carpet. The entire system is driven by JL Audio Class D amplifiers. A 600 watt 4-channel drives the four tower HLCDs, a 600 watt 6-channel drives the six in-boat coaxials and a 600 watt monoblock drives the single subwoofer. Each of the eleven speakers are driven by a dedicated channel. Given the speaker impedances the system produces around 1700 watts conservatively but only draws as much current as some 1000 watt systems. But because the system is highly efficient and linear it sounds similar to many 3000 watt systems.

| A JL Audio 10W6 10-inch subwoofer in a side-firing bass-reflex enclosure. The enclosure is covered in a water-resistant Rhino polyurethane skin.
A resin-coated birch platform elevates the sub enclosure
so that none of the cables entering/exiting the sole are
re-routed. |

| The G3 brackets are beveled to match the indexing on the factory tower and powdercoated in a matching flat black textured finish. A removable bottom plate conceals an internal wire raceway. These solid billet aluminum brackets are 1 1/8-inch thick. A single and very short service loop bridges the bracket and chromed tower tube. The four 14-gauge wires per side are sleeved in a heatshrink jacket and go un-noticed.
Two pair of HollowPoint 770 HLCDs in black powdercoated aluminum pods. All mounting hardware is concealed. These pods are compact and tightly hug the tower.

Three Optima batteries, one starting and two stereo. A master dual battery switch is used in the conventional manner. A second on/off battery switch allows one or both stereo batteries to be selectively brought on line.
|
| |
|
 |
This provision can be used to protect the alternator from two completely discharged batteries after an extended period at rest. Since the two stereo batteries may be used individually at times, rather than a single bank, a triple-bank AC shore charger is used.
An AC inlet was positioned inside of the rear compartment
on the same side as AC access in storage. This way you don't
have to get in the boat to activate the charger.

Blue LED step and courtesy lights were used throughout the interior, including at the floor, coaming pockets and underdash.
Spacers kept the LEDs out of the carpet so the light is unobstructed.

The LEDs behind the factory logo badges were changed out to blue in a manner that is considerably brighter than before. The exterior vents are lit up with LED strips in watertight tubes and are mounted to aiming brackets. A reflective treatment at the back of the vent helps create an effect where the actual LEDs cannot be seen and indirectly illuminate the entire vent.

|
The LEDs were wired into the factory MUX switch via a relay.
