A client from Vancouver contacted Certified Auto Sound and Security in Maple Ridge to discuss his 2016 Sea Ray audio system. The boat comes from the factory with a Rockford Fosgate radio and speaker system. It sounds fine to the average listener, but this client is used to premium sound systems in his vehicles. He wanted us to design and install and upgrade that would offer the kind of performance he enjoys. The client loved our plan! He dropped the boat off, and we got to work on the transformation.
We removed the Rockford Prime Series speakers and installed a set of JL Audio M770-CX-SG-WH 7.7-inch coaxial speakers in the bow locations. We had to enlarge the speaker openings to accept the bigger speakers, but the efficiency and low-frequency reproduction improvement are well worth the effort.
We installed an identical set of JL Audio 7.7-inch speakers in the cockpit area of the boat. We ran new speaker wire through the boat to all four speakers. This step ensures they would get as much power as possible from the new amplifiers.
JL Audio makes some very impressive wakeboard tower speaker enclosures for their coaxial speakers. We used a set of their monster 8.8-inch M880-ETXv3-SG-WH enclosures on the tower. To get these large speakers up and as far out of the way as possible, we used a set of swivel-style mounting brackets. JL Audio offers several different options for the tube diameter of the tower. We were able to order a set to fit this tower perfectly.
Reproducing great bass on a boat is hard. We don’t get cabin gain as we do in a car. So, to make loud bass, we need lots of cone area. To keep up with the speaker upgrades on this boat, our team installed three 10-inch JL Audio M10IB5-SG-WH subwoofers on the rear panel of the cuddy. We made acrylic plastic mounting rings to reinforce the area where we mounted the subwoofer. This reduces rattles and makes sure they sound amazing!
Sea Ray Audio System Amplifiers
A key component to achieving great sound on the water is by having enough power to drive the speakers. We installed three JL Audio MHD Series amplifiers on this Sea Ray. We started with an MHD750/1 to power the trio of subwoofers with a total of 750 watts of power. An MHD600/4 powers the front and rear speakers with 150 watts per speaker. Finally, a second MHD600/4 is configured as a two-channel amp to provide 300 watts to each of the 8.8-inch tower speakers. In total, that’s just under 2000 watts of power on this compact 21-foot boat.
Power Delivery Upgrade and System Accessories
To help power the sound system, we installed a large marine AGM battery from Canadian Energy. We created a new battery box to secure the new Canadian Energy and original battery. We added a multi-battery switch to the boat so that the client can enjoy the sound system all day, and still be able to start the engine with the original battery. We ran 0 AWG pure-copper power and ground wire from the battery to a four-position Wirez distribution block.
To control the subwoofer level, we added a JL Audio MHDRLC remote level control to the HD750/1 amplifier. We mounted the control near the helm so that the bass can be adjusted quickly and easily.
Custom Marine Sound System Delivery
After several days of work, it was time to turn this 21-foot Sea-Ray boat back over to the owner. He hopped on board for a listen and was beyond thrilled with the way it sounded. Everything was clear, and the bass was rock solid, even at ridiculous volume levels. He commented that this was the way the Sea Ray audio system should have come from the factory.
