3. Connecting a 3-way

system using active crossover between woofer and midrange.

You can use all 3-way speaker

systems in this example. You can also use any 2-way system in combination with a separate mid bass speaker.

Speaker impedance must be 4 ohm. If the head unit has only one pre out a Y-cable must be used.
