ice cube..throw away ur passive...u not onli can run active...u can now run ur system FULLY active...got band pass...

oh thanks mr.yong.. will put aside the passive crossover and go FULLY active.

Just thinking that the caliber 1600w 4ch is way too powerful for just the 6.5" and tweeter....

icecube,

u check the amp. im very sure it mention it said MAX 1600w x 4. not norminal power. whahaha. so expect only 1/3 of the power is only real and that still have to divide by 4

ya i think its around 200rms perchannel maybe..coz i blast my b52 (ori one mind u) and cant turn the gain to full becoz the sound start to crack already and i cannot bear the bass already......... LOL.... [btw,i bridge the 2 channel to whack the sub]

I think that Caliber amp is way over rated and somemore it is rated at Max. The more realistic rating shall be in RMS, or in continuous power output. So in real life your amp will most likely be just about 4 x 110W RMS. Remember though, set you amp input sensitivity gain to Min and the HPF for your tweeters to be above 3,500HZ before you start to play and tune, or else you'll end up with 2 smoked tweeters!! :lol: If you need any help on the tuning part, just let me know.

Sifu ... Mohawk MX 3I e-Xover can run full active ?

http://www.mohawk-audio.com

Will i need to use back my passive Xover if i install this one ?

 

[Zenn]

sorry the mohawk website doesnt provide specs of the crossover.

 

[Viperize]

http://www.mohawk-audio.com/sig%20spec.htm

Please refer to MX 3I

 

[pisces23]

Sorry to say, your MX31 is NOT a full active crossover.

 

[Zenn]

from the specs it says can do either front/rear sub or high/mid/low, so i guess it can la, but just guessing only, never see it for myself.

if u want to run front/rear/sub u will need the passives for both front & rear components.

if u want to run high/mid/low u wont need the passive, but u wont have any rear components,.... or u can power the rears directly from HU power if needed.

 

[oldskolboyz]

Hi, from the spec can..either run it in semi or full active..

1)run full actice with 2 input (left/right) only either from front or rear output of HU... if your HU have Sub output then much better coz U can set-up your system in 4way....How to do it.. Your MX31 can drive 3 component speaker..low-mid (midbass) >6.5', High-mid (midrange)
2)run semi active U need 4 input rear & front from HU...with this set-up U get fader control...output will be like this front &rear band/high pass + low pass (sub), but sub 1 I did know coz didn't mention in the spec from front or rear output... If from rear output that give U problem...coz your fader control not usefull...your sub will follow your rear speaker..if you reduce rear volume your sub also reduce..

IF I LOORRR ... I CHOOSE NO: 1 SETUP...BUT NEED EXTRA MONEY...COZ MINIMUM WE NEED 2 4CH AMP (GOOD 1 LAA) OR 2 2CH & 1 4CH AMP...
