halo i just want to know what the actual function of CROSSOVER because i just new to play ICE,my car right now doesnt have crossover yet but have tweeter+midbass speaker,so if i add 1 4channel amp to support my front 2 midbass speaker without crossover is it okay?

First you google for audio crossover
Then maybe you find several sites like this:
http://en.wikipedia.org/wiki/Audio_crossover

Later you need to know what is active(electronic) and passive crossover.

Basically, you will find crossover alike function that filter out high and low in most amplifiers. The HPF and LPF to 'cut out' the bandwidth that your speakers can't produce.

I am not saying those substitutes are good enough to replace the real crossover for those ICEr

mean if wana get more sound quality then i need go for crossover for my amp?

get an active HU if possible

bibbygirl,what mean active HU? i using pioneer 1050u only..how to know if mine 1 is active or not?

Active HU or active x-over?

active x-over gua i think her meaning...btw,active x-over is better?

Yes, active x-over allow you more control of frequency range- more accurate. And this electronic is so affordable nowadays.

oh..if i but components set already included crossover right?what type of crossover are that?

those are passive, u can't change the setting... unless they r those hi ends like alpine F1 or focal Be. some passives can set the attenuation of tweeters, meaning to set it louder/sharper or vice versa.

ooh..if my car dun hve crossover but only have amp...my sound will be better also?

i would say active crossover are better... some passive setups are way better than active...

how to knw whether the crossover is active or passive?

HU > Pre-amp (can skip) > Active- x-over > Amp > Speakers

Normally there is a capacitor or x-over come with ur componet set as it needs to isolate ur mid (mid-high) and high to woofer and tweeter.

I would say if u plan for a sub, an active x-over is a must.

if no sub ?thn x-over is not a needed rite?

The electronic-over....Put la better if you can afford, is worth it...my 2 cents.
But at least u hv 2 hv passive one in btw ur amp and ur front's tweeter+mid

ok..so i also need an component set right?

A component is better for starter instead of mix n match on ur own

okay bro,thanks for ur information!

xover is important regardless of any setups

xover, whether passive or active, is to perform separation of frequencies to the correct drivers

example
2khz-22khz highpass @ -12db for tweeters
80hz-2khz bandpass @ -12db for midbass
20hz -80hz lowpass @-12db for subs

now, passive means the highpass for tweeters and lowpass for midbass is fixed by the manufacturer or you can make a custom made as well
as such, tuning will be slightly harder as the xover points r fixed
therefore imaging, staging,height, depth and width is pretty limited
but if you can modify ur xover points or hv the right combination, the passives gives better character due to its capacitors and coils

for active, all points are variable
active has two types....analog and digital.
digital some are built into HU and the rest are mostly sound processors like Alpine HPX-701
i prefer analog e-xovers like TRU F1B, Zapco, KEF, Sinfoni and so on

since i am into passive setups....no regrets moving back to passive

and one more thing
some of you may ask whether i need a sub or not, will it be to boomy and so on

if your tuning is proper and level matching is correct,
u will enjoy any songs
and it all depends on ur cd recording
no longer equipment barrier
