new to car stereo stuff but just got some stuff from a buddy. Want to hook up one of the amps he gave me to my 6'9s, but I need to learn about crossovers. 1)what the heck are they for and what do they do, and 2) how in the world do they get hooked up?

 

1. Crossovers send different frequencys do different speakers. You dont want your 4x6 or 6x9s playing notes that your subs should be playing so you hook them up to a crossover so that they arent playing those frequencys. so basicly the send high frequencys to high frequency drivers and low frequencys to low frequency drivers.

2. they are hooked up simply by hooking up the speaker wire from your head unit, or amp, and then speaker wire from the crossover to the speaker. most decent to high end decks have them built in, as well as many amps. but if your getting component speakers they should come with the separate crossovers.

 

a high pass crossover will let all higher frequencies above your crossover point through
and
a low pass crossover will let all lower frequencies below your crossover point through

crossovers are rated in db/octave...the higher the better. Meaning if you have a 24db/octave crossover it will limit frequencies a lot better than a 6db/octave crossover. However for most uses a 12db/octave is fine, you wont need to spend all the extra cash on a 24db/octave

 

thanks. :hail:
