• Hmmm.......... now how do i go active with the setup frm here?
• How do i begin?
• Do the cross over points depend on the frequency specifications of the drivers being used.
• What are the other things to look out for ?

See, i told you i really am in Kindergarten when it comes to my ICE journey.

[St. Anger]

Is there any place where i can get cross-overs OTC or do i need to make one for myself. If so, then i'm afraid i have an uphill task on my hands. SOS !

As my HU has on-board 3-Way Active crossovers, i'm thinking if
the 4'' co-ax can be linked to the two-way components and wired to the HU crossover to go 3-way active Jugaad style. Thus, in total, 6 ch of amplification would be required and the remaining 2 channels, bridged to drive the sub as usual.

You could try the following:

1. Disconnect the tweeters from your component set.
2. Mount the 4" coax in the stock location in the dash
3. The 4" coax is already a passive 2-way speaker. High-pass it using your HU active crossover and connect to 2 channels of your 4-channel amp 1
4. Bandpass the 6.5' midbass drivers using your HU active crossover, connect to other 2 channels of your 4-channel amp 1
5. Lowpass your sub using your HU active crossover, connect to bridged 2channels of your 4-channel amp (as you are currently doing.)

In this manner, your are using the tweeters of your coaxes and the passive XO connecting them to the 4" driver.

Pros - you have a true 3-way front stage without need for any external crossovers, also because your tweeter & midrange (in this case the 4" coax driver itself) are coaxially mounted, you should get a more coherent sound.

Cons - the tweeter on the coax may not be as good as those on your compnents, you cannot select crossover point/ slope b/w tweeter & midrange, no separate level adjustment for tweeter & midrange either.

It may sound a lot better than you expect. Try it out and see if you like it, and let us know

@ Flying Bong, Thanks a ton for that, it really sounds interesting. Will try out your suggestion and report back. It'll take a while though. Cheers

Gurus.
What are the pros and cons of going active.

a. Will the mid-bass increase.
b. Will there be harm to compos? ( if i give all the power of JBL 1004 to compos rated at 120w rms)

Opinions needed
Thanks
Abhinav

What do you mean?
If you mean provide power to your components,no problem,but if you are saying that over power them then yes,it will damage them.

[abhinav.gupta88]

I mean giving power of all the 4 channels to one set of compos.

Guys have been using this.

How much maximum power can i give to the compos rated at 180w max and 120w rms.

[Technocrat]

From the little that I know its not just the wattage but also the frequency range that you are feeding to the components which will determine how much power they can handle.
Does your HU allow you to feed in exact frequency ranges for tweeter & midbass separately? If yes then you would need to know how much max power the tweeter & midbass can handle in that frequency range.

Hope this helps & somebody correct me if I am wrong

technocrat.hx-d2 does not play mp3.it doesnt even plays 'recoeded cd's' properly.

[Technocrat]

Yes It doesnt. I had corrected my statement just two posts after the one you have quoted

why do you want to increase the mid bass??u want to make it sdiund like a 'boofer'

You can power the speakers to even double of their rated power,but you have to careful with gains and HPF n LPF.
Going active means that every speaker will have it's own amplification channel.Rest you can set the frequency cut off acc to driver specs.
End result of going active depends on tuning and more tuning,it doesn't ensure positive results.It's an experiment!

gill badshaahooo you have to listen to sam_786 install,i am sure after listening to his install you will not say its a experiment.
tuning active install is the one of the most difficult task to do in audio but hats of to jb,gunbir.

[Gill]

Credit goes to good installer KK. It's the installer who makes the difference.Gunbir and JB are one of the best we have!
And a good installer makes that Experiment, A demonstration.

very well said gill.
