how do i setup 3 way active setup using the HU?

So if you have a HU like the 9855 and switch to an active setup then you lose the time correction, yes?

No sir. You have separate time alignment for each individual channel //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif...

The only time you'll have independent channel time alignment is when you're active.

i'm not quite sure if thats true. i'm pretty sure on my HU if i go passive i still can control each individual speaker as long as i'm in pro mode and that my passive setup is bi-amped.

Depends how you interpret what he said. My 9835 in passive has individual TA on each of the 4 channels, BUT if he meant individual to each component (each tweet and mid), then you can only do that with active, obviously.

i guess i interpreted it with your first suggestion.

Still ike it built into my HU tho...

Other than the onboard EQ which isn't defeatable in most head units and time alignment I NEVER use any onboard processing from a head unit. I have a 3 way front stage and a pair of subs or as some call it...a 4 way system. 2 way active crossover with passive 3 way for the front stage and 1/3 octave EQ. I'm just the kind of person who likes all "seperates" when it comes to car audio. That way if you want to upgrade your EQ, crossover or headunit you don't have to change your whole system layout.

I do agree that a headunit with everything in it is a better value and is easier to set up. But it will never match the flexibility and over all quality of seperates.

Ok, I have an Alpine CDA-9813, I want to try the 3 way active setup. Have componets speakers, front and rear and a JL Audio 300/4, the sub is a JL Audio 10' powered with a 250/1. My question: Do I have to change the settings on the Amp 300/4? Thanks, good information here, my email is EJL574@AOL.COM.

If you want to go active, you will have to ditch the component set in the rear. Unhook it from the amp.

Now, you will need to pull out your HU... and flip a little switch on the bottom to "3-way" mode. Then, you will need to run your "front" RCA's to the front 2 channels of your 300/4, this will power your front set of tweeters only. Next, run your "rear" RCA's to Channels 3/4 on the 300/4, this will power the front set of mid ONLY. You will need to select proper XOVER slopes and frequencies from your HU. This will feed the proper signal to the amp, and the amp will then power your speakers within the corret bandwidths.

That's like a quick *** overview of what to do...

OK, it sounds a lot better 3 way, like it a lot, "You are the man".

Now, I have my wife's SUV, and want to do some work on it, to keep me busy over the weekend, I like this hobby.

I have two JL Audio 6W0 subwoofers (4 ohm), set of JL Audio Tweeters and two MB Quart RCE-Woofers 5.25. Can these JL Audio subs be used as mids?.

Where can I get a 3 way electronic crossover? And wich one you recomend?

She has an Alpine CDA-9856 so she can play with the Ipod and has also a JL Audio 300/4 amp. Only powering a set of components up front MB Quart RCE-216.

So the rear channel I want to use it for a weekend project. If it makes sense //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

I trust your judment and I am willing to compensate you, and please I dont want to offend you, I am a firearms consultant and I do charge for things like this.

Thanks

Look into something like this Audiocontrol...

http://www.woofersetc.com/index.cfm?fuseaction=product.display&product_id=1259

As for the 6W0's, I'd use them MAINLY as "subwoofers" but they should be able to extend into the midbass area pretty well without a problem. With the Audiocontrol piece, you can take them up to 200-300hz, then have your mids (MB Quarts) take over from there. Then naturally your tweeters for the high end.

Essentially, this AudioControl piece will go in-line with your RCA's. So it'll go HU -> AudioControl DXS -> Amplifier.

There are a few other choices, but this digital AudioControl piece is GREAT. If it's too much money, you could try to find a Coustic XM6... but it has a shit-ton of knobs to adjust... and it A LOT harder to configure to an exact frequency. It also only offer 18dB/oct slopes //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif...

So, if it were me... I would use the AudioControl piece. Easier to use, able to dial in on exact frequencies, stricter slopes (up to 24dB/oct), and just a great unit.

Let me know if you need anything else.

Thanks, will let you know as I get the audio control. Cruchfield sells "Foam Speaker Baffles" is there something better that I can used? Let me know if you need anything on this end.

Take a look here:

Even if you don't do the deadening right now (the actual mat sound deadener)... It's a good idea to take care of the speaker mounting with the MDF spacer and clay. Those foam baffles Crutchfield sells are good, they keep water from getting on the speaker... just make sure they are deep enough to accomodate the speaker... or else they're useless.
