Promise me you are not going to just buy the x-over after reading my xplanation below :D
Before that, trouble from square one. Apply the basic rule first:
Ayam HU -> Good Pre-Amp -> Good Amp -> Good CS -> Ayam SQ
Good HU -> Ayam amp -> ayam CS -> moderate / maybe good SQ
Head Unit is the most important role in ICE.
X-over :
Why do you need tweeters, mid-bass woofers & sub-woofer in your car system? Each component handling different range of frequencies.
Tweeter - about 2 - 20 kHz
Mid-bass - 90Hz to 2kHz
Sub - 20Hz to 100Hz
So, when x-over receive signal from HU or amp it will filter and send HI-freq to tweeters, Mid-freq to Mid-bass speakers and LOW-freq to sub-woofer. Without x-over, you may fry individual component if it is overdriven.
There are two types of x-over, passive x-over and active/elecronic x-over. Passive is the one comes together with Component Set Speakers.
Active / Electronic x-over is the one need power supply 12v to operate. Also with many switches and selectable freq. Here, with a proper and sifu fine tuning, this is how you get a clean sound in a small room, your car!
