2005 Mastercraft X2 Marine Audio System We found the previously-installed system to be a huge mess. The whole system is powered by the single Wet Sounds amplifier. The Wet Sounds amplifier was mounted up out of the way in the storage locker. The existing tower speakers were retained for the upgrade. JL Audio component speakers were added to the bow of the boat. The new Clarion radio added more features and SiriusXM. A Clarion wired remote was added to the system. The selector switch allows the client to turn on or off the auxiliary battery.
