A passive crossover splits up an audio signal after it is amplified by a single power amplifier, so that the amplified signal can be sent to two or more driver types, each of which cover different frequency ranges.
Do I need a passive crossover?
Why Do You Need A Crossover? Every audio system, including the one in your car, needs a crossover to direct sound to the correct driver. Tweeters, woofers and subs should get high, mid and low frequencies respectively. Every full-range speaker has a crossover network inside.
Is my crossover active or passive?
The crossovers that are most commonly used in car audio systems are passive crossovers. They are called passive since they don't require any kind of external power source to run. A passive crossover is powered by the audio signal that streams through it.

How do you choose a passive crossover?
Tips for Setting the Proper Crossover Frequency of a Subwoofer
- If you know your speaker's frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanly.
- The most common crossover frequency recommended (and the THX standard) is 80 Hz.
Can I connect tweeters to door speakers?
You can connect two or more tweeters in series by joining the amplifier and the speakers using a single cable. Suppose you have four speakers, A, B, C, and D, and an amplifier. In that case, you can wire the voice coils in series by connecting the positive terminal of A to the amplifier's positive terminal.
What is a good crossover frequency for car speakers?
80 Hz Set the crossover point around 10 Hz below the lowest frequency your speakers can produce without issue. (keep in mind that the most common recommendation for crossover frequency is 80 Hz).
Do passive crossovers Rob power?
The passive does not split the power in half anywhere but at the crossover point. 2. Normally when running passive, you send a full range signal from the amp to the crossover, only to have the crossover cut off frequencies not needed, and roll-off others.
Do passive speakers have a crossover?
The use of an active crossover in a speaker means that you can use that active crossover to send the signal to seperate power amps in the speaker. In a passive speaker when the signal goes through the crossover after being amplified, some of that power dissipates in the crossover and never makes it to the drivers.
