A client from Chilliwack recently contacted the product specialists at Certified Autosound and Security to inquire about upgrading the subwoofer system on his new Malibu Wakesetter Supra 22 LSV wakeboard boat. The factory JL Audio sound system includes three amplifiers, speakers, tower speakers and two 10-inch subwoofers, but the client wanted more bass from the system. We had a look at the boat and came up with a plan to add a pair of 12-inch subwoofers and an additional amp to deliver the bass performance the client wanted.
Wakeboard Boat Subwoofer System Upgrade
The existing 10-inch subwoofers do a good job keeping up with the four wakeboard tower speaker pods and the speakers mounted around the interior. With that said, they don’t offer the punch that the client wanted.
The plan for the Wakesetter 22S LSV was to add a pair of 12-inch JL Audio M12IB6-SG-TB to the rear of the boat under the bench seat. Our fabrication team created a custom enclosure out of HDPE plastic to house the massive subs. The enclosure is bolted into the storage compartment to ensure that it won’t move even when the boat is pounding over the waves.
With existing vents in the hull around the seats, bass from the new subwoofers is able to exit the storage space easily and blend into the rest of the system.
Each of the JL Audio M12IB6-SG-TB subwoofers is designed to handle an amazing 600 watts of power, thanks to a large voice coil former and winding. Of course, significant power handling doesn’t mean much if the speaker can’t move significant amounts of air. These 12-inch subs are designed with a 0.73-inch Xmax spec that means the cone can move forward or rearward from rest by about ¾ inch with minimal distortion. Truly, there are no marine subwoofers available that can match the performance capabilities of the M12IB6-SG-TB.
Marine Subwoofer Amplifier
The client chose a monster JL Audio M1000/1v2 to drive the pair of subs and keep the look of the amp rack under the passenger seat coherent. We added a second mounting panel above the M800/8 amplifier that was already in the boat and wrapped it in gray carpet to match the original panel. Our technicians ran Stinger 4-AWG power and ground wire to the boat battery bank and installed a marine-grade circuit breaker to protect the system. It took a while, but we ran a pair of 12-AWG Stinger speaker wires from the amp to the rear of the boat.
The M1000/1v2 is rated to produce an impressive 1,000 watts of power into a 2-ohm load and is designed with features like a corrosion-resistant powder-coat finish on the heat sink, a conformal coating on the main circuit board and stainless wire connections to prevent corrosion in challenging marine applications.
In terms of sourcing an audio signal for the new subwoofers, we tied the new amp into the existing subwoofer amp using a set of Y-cables and new JL Audio interconnects. The client has full control over the boat’s subwoofers from the factory MaliView 12-inch touchscreen radio system, making the system seamless and easy to use.
Marine Audio System Installation Experts
After a few days of work, we had the new subwoofer system installed and configured to work with the existing equipment. The addition of the pair of twelves truly brought the system to life. The client can crank up the volume, and the bass is clean and solid, even at the end of the tow rope.
The client returned to Certified Autosound and Security to hear the subwoofer upgrade on his Malibu Wakesetter 22 LSV. He was thrilled with the way the boat sounds and loved the attention to detail and craftsmanship our technicians put into the project.
