Since its inception, Gold Coast Car Sound has always focused on proving solutions for its clients, no matter what the vehicle or situation. Marine vehicles have played a huge part in GCCS history with many of our customers opting to treat their boats and jetskiis to some audio indulgence. As such, GCCS have always carried a full range of marine grade equipment to provide customers with the same audio performance they would expect from their cars.

Ski/Wake Boats have become a popular marine vehicle to upgrade as factory audio systems rarely perform to customers expectations. This particular Crownline example was factory fitted with a Clarion headunit and Polk Audio speakers and amplifiers. As the boat was fitted with aftermarket engine parts, the owner wanted more volume for the skier and more bass for the in cabin occupants to drown out the engine noise. GCCS went to work designed a full Alpine Marine audio system that would blow away the owner and his friends on their next boat outing. 

The factory pair of 7inch Polk Audio tower speakers were replaced with two pairs of Alpine Type-R marine 7inch speakers. One set utilising the factory cans and the other set fitted in the Alpine beautiful fiber-glass cans. This provided four 7inch speakers all being driven by a marine series Alpine PDX4.100M Amplifier.

The factory system only provided two speaker positions in the cabin, one front and one rear. GCCS technicians designed and installed extra panels which would allow two more speakers to be installed. The in-cabin setup consisted of four alpine Type-R 7inch speakers mounted in a standard car configuration, two front and two rear all driven by a second Alpine PDX4.100M amplifier. Under the rear bench seat, GCCS technicians built a downward firing box housing a Alpine Type-R 10inch marine subwoofer to bring some bass to this monster system.

The entire system is being run by a Alpine IDa-X100M marine grade amplifier iPod/USB receiver paired to a Alpine MC20 commander remote control. Overall, this system is a monster, providing more than enough sound to keep any boating enthusiast happy.
