Premium cars deserve premium sound – and this includes a deep and punchy bass reproduction which the basic speaker setup in Mercedes vehicles doesn’t deliver at all. However, the perfect solution is quite simple – the heavy-duty 8” / 200 mm woofers of the UP W8MB-S4 system fit perfectly into the original mounting positions in the bulkhead and provide exactly the right punch that you can feel and which brings music to life.
Especially in combination with one of our DSP amplifiers these subwoofers reveal their full potential in respect of dynamics.
