A client of Certified Autosound and Security from Chilliwack was at our shop inquiring about upgrades for his Monterey’s audio system. We happened to have our shop boat in the store getting ready for a show, so we let him have a listen. Once he heard what was possible, he told us to do what we could to replicate that performance on his 224FS bow-rider.
Tower Speaker Upgrades
We had installed a set of Rockford Fosgate PM282 8-inch tower speakers on the boat last season. To upgrade the sound for the skier or wakeboarder, we added a second set of 8-inch cans and upgraded the amplifier to a Punch-Series PM400X2. This amp would provide each enclosure with up to 100 watts of clean power.
As you can see from the photos, all the wiring for the tower speakers is routed cleanly through the aluminum frame of the wakeboard tower. There is only a small loop visible around the forward hinge on either side. The client can fold the tower down if required when moving the boat or putting it in storage.
Interior Speaker Upgrades
The next step was to remove the factory-installed speakers from the boat. We chose two sets of Punch Marine PM2652B Black 6.5-inch coaxial marine grade speakers. We wanted to use something larger, the but the speaker openings in the bow and on the sides of the boat are limited in space. There was no way to install an 8-inch speaker in those locations.
A Punch Marine PM400X4 four-channel amplifier powers the new PM2652B speakers. This amp is rated to provide 50 watts of power to each speaker, but the birth certificate included with the amp said it was good for more than 80 watts of power.
Marine Subwoofer System Upgrade
The last speaker upgrade for this Monterey Rockford marine audio system upgrade was to create a custom enclosure for a pair of Rockford PM212S4B 12-inch subwoofers. The subwoofer system is mounted off to the side of the engine compartment and is powered by a single Punch Marine PM1000X1BD 1000-watt subwoofer amplifier.
All three of the amplifiers are mounted together on a sheet of HDPE plastic. The amps are spaced up off the floor of the boat by several inches, and all of the wires are routed upwards to keep everything safe and dry.
Rockford Marine Source Units
A Rockford Fosgate PMX5-CAN marine-grade digital media receiver feeds the sound system. The PMX5-CAN is mounted in the glove compartment on the port side of the boat in the factory radio location. To make controlling the system easy, we installed a PMX-1R remote control on the left side of the helm. This remote includes a 2.7-inch colour display and features a rotary encoder for volume adjustment.
The PMX5-CAN features Bluetooth for audio streaming, a USB port for phone charging or playback of MP3 or WMA files from a memory stick. The AM/FM receiver also includes support for Weatherband channels so the client can stay up to date on changing wave conditions and the forecast.
We added a second remote to the system to make it easy to adjust the volume, change sources or change tracks from the swim platform on the stern of the boat. In this application, a PMX-0R remote was called upon for its simple design.
Monterey Rockford Marine Audio Installation and Tuning
It took almost a full week to complete the installation of this sound system upgrade. Running the cabling for the remotes is a time-consuming task. Our technicians finished the installation by configuring the amplifiers for the Rockford source unit and the chosen speakers. They set the crossovers and sensitivity controls to ensure the system would play loud while still sounding clear and detailed.
The client returned to Certified Autosound and Security to have a listen to his boat once we completed the work. He loved the way it sounded and was very impressed with the installation.
