Just like the M4 I posted a couple weeks ago, (See it here) this S5 owner needed more bass than the factory installed Bang & Oulfsen premium stereo could provide. This car came with an essentially useless donut spare tire so it was removed to make way for this dual Focal 10 inch custom subwoofer enclosure powered a Pioneer Digital Series Subwoofer Amplifier.
At CSD Audio, it’s all about clean & stealth. We all want our cars to sound better but don’t want to lose storage space. In this M4, I stashed two Focal Access 10 inch subwoofers in a storage area under the floor. Weight was a major concern for this BMW owner so this box was fabricated mostly from fiberglass and weighs only about 8 lbs. Hidden, lightweight, and sounds amazing!
