crossovers???

[iceteebone 5,000+ posts]

ok what i want to do is run a set of tweeters, 5.25 midrange, and some midbass. my headunit is a pioneer 860. not sure if i'm gonna get a 6-channel amp or a 4 channel and 2 channel. the problem i have is i only have 3 outputs from my deck. i'm a little sketchy as too how these electronic crossovers work. is there a crossover out there where i can have my 3 inputs, then have a low pass for my sub amp, a bandpass for my midbass, another bandpass for my midrange, and a high pass for my tweeters? or is there another way to go about this? as you can tell i'm really dense when it comes to crossovers.

there are some high end crossovers out there that'll do ur 3 channals + sub channal....

what are u talking about with the bandpass for ur mids?

high pass them at say 80 hz. then low pass them at say 350 hz. and have the 5.25 midranges play 350 hz. to 2khz and the tweeters play 2khz and above. also have the sub play 80 hz. and lower.

You can pick up an external 4-way xover (highpass, dual bandpass's and a lowpass), but then you are kinda wasting the internal xovers in your HU.

Or, if the amps you have/are getting have the appropriate built in xovers, you can use a combination of the amps and HU's crossovers to do what you need. HIghpass the Tweets off the deck. Run the midrange & midbass off of the bandpass RCA output on the deck (so it would lowpass the midrange and highpass the midbass), then use the amp's xovers to highpass the midrange and lowpass the midbass. And the subs off of the lowpass output.

That kind of fun, creative stuff //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

PS: If you are going to cut off the midrange at 2khz, then you might as well not even bother with a 3-way //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Let that midrange as high as possible.

i think i got it. hook up the sub to the sub output. banpass the rear channels, 80 hz. to 2khz. then low pass the 2 channels for the midbass at say 350 hz. on the amp and high pass the midrange on the amp at 350 hz. i have a pioneer 860 so it has a 3-way crossover. so now would i just get some splitters to split the rear rca outputs into 4 channels instead of 2?

Yup.

But, like I said......2khz is pretty much a waste for a 3-way setup IMHO. The purpose behind that midrange is to actually play the majority of the midrange frequencies //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

if i put something like this http://ikesound.com/product-product_id/524 on my rear rca's then just high pass the rears at 80 hz. and low pass the midbass at 350 hz. or whatever and i should be all good to go then right? i'll crossover the tweets at like 2khz then on the headunit.

ok i'll just let them play 350 hz. and up. seems easy enough to setup. //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif

You would need two of those (one for the left RCA, one for the right RCA). But yeah. Then you'd bandpass via the HU at the frequencies necessary to highpass the midbass and lowpass the midrange (using your example, 80hz on the highpass and 2khz on the lowpass), then use the amp's xover to lowpass the midbass @ 350hz (or where ever) and again use the amp's xover to highpass the midrange @ 350hz (or where ever). And highpass the tweets via the deck.

He'd have to use that in conjunction with the HU's xovers still. In which case, it'd be cheaper and easier to just use the amp's built in xovers.

However, if you really wanted to use an external xover also, I have a mighty fine 3-way for sale //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

right now as we speak...

i have tweeters running off passives (2500hz 18db)and dome midranges full range past naturally rolling off at 5k... 630hz 6db slope HP off front channels

my mids are bandpassed 63hz- 800hz (24db slopes)

Its very limiting to run full 4way with anything other than a DRZ/P9 or external processor/xovers.....cannot do it fully active otherwise

Here's some pics on my instal i finished up recently adding my midranges...
