Perfect sound:
High quality speakers form the basis of our upgrade systems.
Not only are they better in quality than the standard speakers, they are also more durable.
Our subwoofer is 67% larger than the standard woofers from BMW for its perfect fit.
The bass sounds fuller, more spacious and much deeper, creating an incredibly dynamic sound.
A missing treble loudspeaker is a weak point of the BMW audio system.
All Boxmore BMW sound systems come with a high-quality 25 mm soft-dome tweeter that guarantees unbelievable detail resolution in the treble range.

More volume:
More dynamics and maximum enjoyment.
Thanks to the high quality of the 520 Watt / 610 Watt amplifier, the sound remains clear and dynamic, even at full volume.

Optimally integrated:
Our loudspeakers fit perfectly into the mounting positions provided by BWM.
Thanks to the Plug & Play cable sets, the vehicle remains in its original state.

Attention: Please forward us when ordering your chassis number as the cable harness is pre-configured by Gladen for your vehicle.
