2009 BMW 1 Series Audio Upgrade

As with most BMWs, the sound system from the factory is of very poor audio quality. For this customer, we supplied and installed Hertz HSK163 front 3 way component speakers along with a Hertz Hi-Energy HX300 12″ subwoofer.  These were powered from a Hertz HDP4 for channel amplifier, which was fed by an Audison Bit Ten D for signal quality.  The beauty of the BitTenD is the EQ system that is incorporated to allow full adjustment of sound frequencies.

We traveled from Rotherham to get these guys to fit some reversing sensors to my wife’s car, I’d been before and they were very professional for both alarms and a radio on my van and this time as before they were brilliant. The work was completed ahead of time and one of the guys came out and spent 10 minutes explaining EXACTLY how parking sensors worked which was great as I hadn’t a clue. We are very pleased with both the professionalism of the people and the work in which they do. Perfect!!! Many, many thanks for such a great company.
