From HK to HD, We take BMW's top package and take it to whole different level in Audio performance.
This BMW 640D Gran Coupe now sounds so sweet it needs to be heard to believe it!
Transforming HK to HD aUDIO
For the many HK sound fantastic but for the trained ear its a different story!
Harmon Kardon Is a fantastic option for many, plenty of power, more speakers, a false image of 3d surround and a pretty badge!
Just like all other big brands household icons who get there name plastered on the car door speaker grills these give you that reassurance that what you are buying is the top, the best and be all and end all of the car audio world.
This is the same as saying a Ferrari cant be called rubbish because its a Ferrari, but if you have seen the F1 film Rush when Nikki Lauda calls it "a piece of c**p a sh*tbox" everything can be revised and improved upon.
and this is what we have achieved with this install!

Amplification
to power the speakers from the processor a multi amplifier setup is needed.
on this build we opted for 2 Audison SR 5.600 1000W amplifiers
and an Audison SR 1.500 this mono amplifier produces 1000w RMS to power the dual subwoofer setup
that's 3000w over 11 channels more than enough for this car.

on this system we wanted to take the strain from the under seat woofers and also hit lower bass performance.

On this system 90% of the install is hidden but to control the DSP profiles, System master volume, bass and other controls we installed the Audison DRC MP in a custom made Mount.
