Supplied and fitted at our workshop in Newton Abbot, Devon
 
Product Description
A balanced “Stage 2” system combining APBMW XKE components up front, APBMW X4E coaxials in the rear, and S8-4 underseat woofers for body and impact. This system delivers an open, detailed front soundstage, supportive rear fill, and much fuller low-end presence. Everything fits discreetly into BMW’s OEM locations for a totally factory look.
Note: This package provides a solid upgrade on head-unit power, but for deeper bass and greater control, we recommend adding an amplifier.
