do speakers pull back by electric after they have been pushed?

Question

1.can you have three speakers wired in series as long as they have enough power such as woofer,mid,tweeter, like say 300w x 2 ?
2.how do you no if theres enough power in a battery if you wired it to speakers and a car amp?

Answer 1

The AC current that the amplifier sends through the speaker will alternately repel and attract the cone to the magnet mounted on the back. If there's no power going to the speaker and you push the cone, then it's the suspension of the speaker that pulls it back into a central position, not electricity. The surround around the outside edge of the speaker, and the "spider" which is located behind the cone and attaches to the inside edge of the cone, allow the speaker to flex back and forth but hold it in a central position at rest.

The problem with wiring a woofer, midrange and tweeter in series is that you need to use a crossover to send the bass, treble and midrange sound to the correct speakers. Crossovers don't work with different speakers wired in series.

If you have two or more speakers wired together in series, then you can only connect them to a single amplifier channel. If you had an amp that was 300w x 1, and you connected it to three identical speakers in series, then each speaker would get one third of the total power. Of course, if you wire three 4-ohm speakers in series you'll end up with a 12-ohm load, which would greatly reduce the power output of the amp.

It's not the battery that has to be strong enough for the car amp and speakers; it's the alternator. Most stock alternators won't have much trouble until you add a high-powered amp/sub system. Since the amount of power required for the audio system will depend largely on how loudly you like to play it and the kinds of music you listen to, the only way to know for certain is to try it out.

Answer 2

I could be wrong but an amplifers speaker terminals have an A/C signal causing the cone to move back and forth.

You may need a crossover between each driver, i'm not sure what happens when low frequencys go to a tweeter.
