Product Description
Our most complete non-DSP BMW upgrade. The system blends APBMW XKE components up front, APBMW X4E coaxials in the rear, APBMW S8-4 underseat woofers for punch, and the powerful APBX 10 AS active boot subwoofer for depth. Everything runs through the SR 5.600 amplifier, with a wired bass remote for instant subwoofer control. This delivers a full-range, high-output sound system while maintaining OEM aesthetics.
