What stays factory when you fit subwoofer on a Mercedes-Benz B-Class?

On every B-Class we work on — W245, W246 and W247 — the factory head unit stays; the amplifier takes its signal from the car and under-seat woofers leave the boot free.

Yes — send the reg or the year and generation (W245, W246 and W247) on WhatsApp or the form below, and we confirm the route, the price and the next free slot. The work carries a one-year warranty, and the workshop is in Rosemount Business Park, Dublin 11, Monday to Saturday.
