The whole output power of 40 watts, the impedance of 4 ohms, if each speaker 20 watts impedance 4 ohms, you can take four? CD machine itself four channels, the speaker wattage requirements? The same impedance as the wattage should be the number of tile more match? Do you want another divider?
The host or amplifier output power must be greater than the speaker, so that you can fully play the sound system.Do not have an external divider. But as long as the host or amplifier output power output can be greater than the frequency of the speaker package can be.
: The number of watts required, according to the CD player itself or power amplifier output power can be.
Can not take four 20-watt 4-ohm speakers. Because the host output power of up to 40 watts, connecting four 20-watt 4-ohm speakers easily lead to high load the host output, and finally lead to the host power module failure.
To the professional car audio shop, the technician will be based on your model to determine the configuration
The front of the problem is not to say, I can answer the back, the crossover must be connected, but also a channel can not only have a speaker at work, so the silencers indispensable!
