Utdrag fra test (vedlagt pdf): "If you max the volume all the way up, the sound stays clean and emits a mighty lot of pressure and volume. No buzz or distortion noise disturbs the sound, only now and then you can feel the woofer under the seat working hard at the limit, however, without reaching it. This is perfect tuning, which is only possible with precise knowledge of the vehicle equipment and which really gets everything out. But things were to get even worse: At full volume, you can turn the basses even further on in the sound menu of the radio. And what happens? The sound changes even more in the direction of the dominant bass, but nothing is distorted - try this with a standard hi-fi system... All in all, the BMW sound with the UP 7BMW is scarily good. It sounds clean, pleasant, error-free and perfectly well balanced at EVERY volume." IN-CAR SMART UPGRADE Specifically designed for BMWs and compatible with all ‘Hi-Fi System’ equipment, the Match Up 7BMW comes with a mounting plate and plug-and-play harness so that it can be installed in just a few minutes. It’s an invaluable upgrade, boasting seamless integration, which delivers more power and dynamics to your in-car performance. A seven-channel amp, it includes proprietary ‘Class HD’ amplification that routes extra power to the woofers, resulting in a highly dynamic sound that has to be heard to be believed. The powerful 64-bit DSP runs proprietary algorithms to get the best out of factory speakers, including the centre channel, resulting in a powerful bass response and vastly improved soundstage no matter where you are sitting in the car. 7 kanals Plug & Play oppgradering for BMW HiFi lyd system (utstyrskode S676A*).
