The 30 dB low pass is set to 5KHz and the 30dB high pass is set to 150 Hz operation. All information from 150Hz to 5KHz is passed to the midrange amps, which drive four midranges. All information above 5K is passed to the tweeter amp that drives the four MTX 1 inch dome tweeters. This is provided by six Orion GS-2350 amps and an Orion 24 Gx amp. Monster cable is used for all speaker connections.
Every speaker is fused on the flip side of the amp rack for protection against excessive power.
The amp rack is mounted vertically in the rear of the car. The amps are shrouded in glass, with forced air cooling. To service fuses or make tests, the amp rack rotates 180 degrees to reveal all of the support circuitry. Located on the flip side, from left to right, are the DC power distribution buss bars, speaker fusing, active crossovers, computer and switch interface circuitry. The middle side windows of the car contain huge real time spectrum analyzers.
