Example 5:
System with separate amplifiers for front and rear system with fader.
Separate amplifier for the subwoofers.
This system with three amplifiers and a filter box gives you many possibilities to adjust and balance the
sound in your car so that every speaker plays at the wanted level. This is an advantage compared to
multimode connected systems. It´s also possible to use mid-bass speakers with a passive crossover.
