Mercedes Benz A, GLA, CLA & B-Class sound upgrade for vehicles without factory sound

5-channel upgrade amplifier with DSP, including mounting accessories and plug-and-play wiring harness for Mercedes-Benz A-Class W176, CLA W117, GLA X156, and B-Class W246.

Do you own a Mercedes with a standard sound system and want to improve the sound, but don't want to dismantle the entire vehicle? Here's the solution: a high-quality plug-and-play amplifier with DSP that unlocks unprecedented sound and performance from your vehicle's original speaker system!

The set comes with a ready-to-use wiring harness (which is spliced into the factory wiring harness) and a pre-installed high-power sound setup. We also offer a matching subwoofer with an 8-inch high-performance driver and a tweeter upgrade as optional extras. Even inexperienced installers can easily manage the installation!

Match M5.4 DSP: Concentrated power in a handbag format
Barely larger than a smartphone, but with the performance of a true giant! With an almost unbelievable 360/720 watts RMS/max. output power and five amplifier channels, many a loudspeaker will break a sweat! Such power in such a compact space is only possible thanks to Audiotec Fischer's proprietary Class HD technology, which guarantees sensational efficiency and therefore minimal heat generation. This opens up unprecedented possibilities when choosing the installation location. This plug-and-play amplifier fits behind the glove compartment in most vehicles, minimizing installation effort and eliminating long cable runs!
