Crossover?!?!?

can someone please explain to me what a crossover does an what its for....also how do you hook up rca cables to more than one amp do you plug more rca cables into the output jacks into the amp and so on from there...... thank you

I personally got rid of my crossover, the amps usually come with a built in crossover.

And running the RCA jacks to various amps would depend if the amp has an input and a pass through, if you then split the rca's with Y connectors

It helps your amp on Hz and Bass boost...

A crossover seperates or blocks the sound at a crossover frequency point. For example, it splits the highs and lows at a desired frequency... say 150 hz. So you could send your main door speakers an audio signal above 150 hz, but everything below 150 would be blocked from the door speakers. This is called High Pass (HP) because it allows only the "highs" to pass.

You could then take the "low" output and send it to your subs. They would only get the audio below 150 hz. This is called "Low Pass" (LP), because only the lows are allowed to pass to the subs. This set up is called "two way" because the audio is split to 2 signal paths, a high and a low.

You could also have a "three way" crossover, which would split the regualr RCA audio signal into 3 signal paths. High, middle and low. The high and low are the same as above, except you would pick 2 crossoverpoints. For example, 2 khz and 150 hz. All the audio above 2 khz would go to the tweeter, the audio below 150 hz would go the sub; and the audio between 2 khz and 150 would go the mid. All the audio signal above 2khz and below 150 hz is blocked from the mids. This is called Band Pass (BP).

If the crossover is before the amplifier (like the ones mounted on the side of an amplifer) these are called "active" crossovers. Because they have built in powered electronic circuits and preamplifiers. These signals are then split to different amplifier channels for each band (High, low, etc)

If they are after the amplifier, like the ones that come with a set of component door speakers, these are called "passive" because they have no powered electronics circuits and work only off the speaker wire signals without addtional electrical power.

Passive crossovers are better for low power systems like component door speakers They are much cheaper, because you don't need seperate ampifer channels. Active crossovers are better for getting more performance from amplifiers in high power systems like subwoofers.
