yupe ....like they say ...3 way is d hardest to setup ....semi active is when d player can support only 2 way system ....

in a 3 way speaker ....it consist of
2 tweeter
2 mid (the smaller speaker)
2 midbass

example .....for a HU that support 2 way active system ...there will be 3 pair of output from the HU .....1 pair is for d tweeter , 1 pair is for the midbass and 1 pair is for d subwoofer.....there is 2 different ways of playing semi active ......

first one is to use the tweeter output to drive the tweeter and the mid in this way u can control the high pass of the mid .....the crossover point of the mid and the tweeter will be determine by the original crossover......then the midbass will be controled from the midbass out from your HU

the second way is to use the midbass output to drive the mid and the midbass together ....this way the tweeter will be fully active.......

if u wanan run 3way full active then u have to either change your HU to a better HU or get a processor such as d Alpine 700,701 or the 900.....

there is e xover like Trutech F2 tht has 2 channle of bandpass which you can use for 3way setup...

as for processor... the 900 is not really a choice as it only can be used with the DVI-9990... other than tht its pretty much a useless thing...

cheers...

H900 can be use as standalone proc

the one which need to pair with 9990 is H990

thanks for correcting me...

cheers...

Gee.. I can't get it right.

For my ICE, my HU only have 1 RCA pre-out. Which goes in Active crossover, then to amps. Should be this way right?

In order to full active, what should I do or device to get? What option I have?

Getting a processor can it split out more RCA output? HU -> processor -> Active crossover, this way?

Really burning up my time on recall the knowledge.

to get active for 2 ways

HU-> active crossover-> amps 5/6 channel -> speakers/subs

Currently I have 2 amps, 2ch n 4ch. 2 ch use for Sub. 4ch using for front n rear. Anytime I can ditch rear speaker, doesn't matter to me.

So to get Full active 3 way I lack of RCA preout right?

3 way external crossover ?

the only crossover that can go 3 way that i can recall is TRU F2
but this is real rare species

but u can forget bout preout cos u HU->Crossover only need 1 pair of RCA

but u're using 1 x 2ch and 1 x4ch
u can only go front 2 way

eh? he can go 3 way le...he said he can ditch out the rear spk...then he can go active for the 4ch and sub remain 2ch

or u mean 3 way comp set?

So conclude that is Active crossover unable to support. 2way to front, then would it be a waste to have a 3 way comp set?

Yes howiechoo.

Hm... actually there's another crossover that can go 3-way, just that it's lack of exposure, the AudioControl 4XS can actually do 4-way front stage + subwoofer, total 5-pairs of output

GRexer,
4-way front stage? I don't get it. Eventualy I feel is getting more complicated. The crossover support 5-way out mean can go to more channel rite?

4XS isn't normal analog crossover i reckon?
using chip?
play wit it once and screw up the whole setting

Yeah... it's analog and chip based, a bit of a troublesome when doing the tuning, but at least, i'll know the accurate point of crossover Maybe i'm juz always trying to be perfect, which i'm not

I now have 2 setups in 2 different cars, one fully digital so to speak, and the other is fully analog

Gee, I'll prefer simple method. As for myself not good in tuning, can say I don't even know about tuning. I just duwan to waste the 3way comp set, as newly installed.
