My signal starts out from the ODR head unit & changer or Mini-Disc. It is then fed into my DEQ30. The DEQ30 is a Digital EQ and therefore adds no noise to original signal and because the signal is fed via a fibre optic cable it cant pick up noise from cars electrical system. The light then travels via fibre optic cable to an APOGEE DA 1000-20E DAC (Digital to Analogue Converter). The Apogee DAC is a studio quality DAC and is arguably the finest of its kind. This device is used to covert the light signal back into an analogue signal for the amplifiers to make louder. The signal is fed in to an Audio Control MVC that allows me to control the volume via remote control from drivers seat. The Head unit is always at full out put (volume setting) and the MVC allows it to be adjusted. This is done just prior to amps.
The Amplifier takes its part of the audio signal, makes it louder and sends it to the appropriate speaker.
The Phoenix Gold ZEROpoint ZPA.05 runs the Dynaudio system 360 speakers in stereo. The signal is then fed to a passive (phase correct shallow slope) cross over, that divides the signal after it has been made louder and sends to the appropriate speaker ie: high freq(treble) to tweeter, midrange freq to midrange speakers, etc.
The tweeter and mid-tweeter are mounted inside tubes which are then mounted to the kick panels. This allows precise placement and angling for hopefully optimal imaging and staging.
The 8"speakers are mounted in front of the front seats in sealed boxes facing the roof but angled slightly towards listeners.
The Phoenix Gold ZEROpoint ZPA.03 is also bridged into mono driving two Phoenix Gold XMAX 12" Sub Bass Drivers wired in a parallel, below 50-70hz. The subs are run in their own custom sealed box.
Stay tuned for Pics and Diagram.
