a electronic crossover

to seperate the high frequency and pass it to tweeters,the mid frequency to the mids or driver where u ussually find at the door panel,and of course the low frequncy to the subwoofer(usually big and bulky in your boot)all this u need an amp to drive all the invidual speakers. :D signal -> e.crossover -> amp -> speakers

a passive crossover

same stuff u find up there but this stuff doesn't need to feed in power :D usually come with those component speakers.the small little box :D signal ->p.crossover->speakers

pre amp

for use of those classic HU.where u dont find extra output for the rear,front and low :D to split the signal to the amp(s) to drive either front or rear or sub.note a pre amp doesn't come with crossover.

a small example of what i trying to say :D let say i wanna put a three way setup infront and rear of my car.how should i do it?that where the e.crossover come in :D a seperate 1 always better than those built in in the amp :D so an eq just tweak the sound in whole

PS:howiechoo why u need both running together?,all the latest HU can replace or does have a preamp funtion these day

Drop the preamp and get a crossover... pre-amps were made for older HU's whereby there was no fader controls and limited outputs.

Add the preamp cost to the HU cost and get a better HU.

bro. can give some tips to make it better. thanks a lot

err.. quite hard to give opinions if havent heard the sound but I'll try...

You need to post up what you have in your system first.

 

[Bert]

Most mordern crossovers can accept 1 input and have 2-3 outputs...

Then the level matching btw front and rear will be done via the amps...

Saves money too!

the thing about pre-amps is, it usually makes the sound worse and introduce more noise into the system, so better save up for a good crossover.
