Some cars sound good. But only with a subwoofer does music sound the way it was meant to. That deep, full bass you feel through the seat, without distortion or rattles. That's what sets a good audio system apart from standard sound.
At EYE4AUDIO at Diessen we build in subwoofers that not only sound impressive, but also integrate perfectly into your interior. No loose boxes or wires, but OEM finish that looks like it came that way from the factory.
A subwoofer starts at €249.95 and the installation costs start from €399, depending on your car and chosen configuration.


Most factory audio systems lack depth. It sounds clear, but not full. As soon as you increase the volume, the bass disappears or becomes dull. A subwoofer solves that by separating the bass from the rest of the sound.
The result is balance. You hear the details, feel the energy and enjoy music without noise or distortion. Whether you listen to house, hip-hop or jazz - with a properly built-in subwoofer, it sounds the way the artist intended.
At EYE4AUDIO, we use brands such as Audison, Vibe, Edge, Option, Hertz and Audiocontrol - all known for their clean sound, reliability and workmanship.
Every car and every audio system is different. That's why we never work with standard solutions. First we look at your car, the type of radio, the current amplifier and the desired sound. Then we put together a system that fits perfectly.
The subwoofer is placed in a location that best suits your interior:
in the trunk, under the seat or integrated into the side wall.
We completely eliminate the wiring and ensure that the installation connects seamlessly to the original radio or CarPlay/Android Car box.
Then we adjust the amplifier and subwoofer professionally with measuring equipment. This gives you deep, controlled bass without resonance or loss of sound quality.

Our strength lies in the combination of technology and finesse.
OEM finish without visible cabling
Compatible with original radio systems
Tailored sound to your style of music
Two-year parts and assembly warranty
