Hey friends, The description does sound like a mouthful and somewhat amusing! I know! hard to believe, huh? LOL

This is one of the designs a company technician showed me when I visited the JBL/Harman International global headquarters in Northridge, California in the mid-nineties when I represented/worked for them. This was a period in time when aftermarket companies were just beginning to partner with auto manufacturers. This was also the time when I met 'the man', the founder, Dr. Sidney Harman (a Canuk) who, unbeknownst to me, who just so happened to live just six miles from me at the time when I lived near his Palos Verdes home.

As most everyone here knows that the factory Infinity amps in our Crossfire is from the Harman International group. Bi-amping the system helped by separating the high pass and low pass signals to accommodate high dynamics and transient passages especially in the bass region. Signals benefited from being clipped at high volumes, among other features involving speed sensors, saving the audio equipment from meltdown. I think the designers were thinking especially about the roadster owners' top down music enjoyment when they put the audio system together.

Without prejudice, this block diagram of the amp design might help some to visualize the two-channel stereo signal flow coming from the headunit.....
to the amplifier units' internal active dividing/crossover network that separates the Low Frequency effects from the High Frequency and Middle Frequencies.....

to where the signals are amplified by the two amps.....
then ending up at our speakers.



Thanks, everyone! Carry on!
