One of the most iconic sports cars in the world, the BMW M3. Alpine electronics have had a long partnership with BMW being that many factory BMW audio upgrades are supplied by Alpine. As with the M3's engine and chassis, BMW recognisies the importance of balance; audio systems are no different. An ideal audio system should be designed with balance in mind, the individual components should all work together to provide the listener with a single perfect blend of sounds.

The owner of this M3 wanted a perfect blend, not too heavy on bass or vocals but a smooth blend with the capability for high volumes. GCCS designed a system which would bypass the factory amplifier and use standard BMW headunit as its primary source. The factory amplifier with replaced with a Alpine PDX-5, this 5 channel digital amplifier was small enough to fit in the factory amplifier position allowing GCCS technicians to create a truly seamless installation. The front speakers were replaced with the top of the range 5inch speakers from a/d/s/, the 345is components. Sound from the rear was filled by a pair of 6inch Alpine Type-R speakers in the factory position.

To round out the system, a Alpine 12inch Type-S subwoofer was installed in the Alpine designed enclosure for optimum performance. Overall the vehicle presented a beautifully balanced sound with great front stage and solid tight bass.
