Going active - which processor?

Not sure the exact lay out of that crossover, so I would need to see a picture or manual to give you a concrete answer...
I would use both outputs (front/rear) because I believe your deck does have T/A that you can play with at the very least...

For the crossovers, use the x10 switch for your tweeter high pass and woofer lowpass...I could have sworn it had individual crossovers for the woofer lowpass and tweeter high pass but I guess not....just set it to around 3500hz....

Try the gains at around half way then set your amp gains with a DMM to be safe...

heres a pic i found online:

as you can see there are 4 knobs in the center for filters. from left to right: sub lowpass, mid highpass, mid lowpass, tweet highpass. so yes you can bandpass the mid, but i dont understand how these filters are applied. do they apply to all channels no matter what? like, you couldnt set seperate filters for front vs. rear?

so if i use front for the tweets and rear for the mids, will these filters filter out all frequencies below the tweet highpass frequency just for the front signal, and filter out the frequencies outside the bandpass setting for the rear channel? i dont want to go and highpass the mids at 4000HZ or lowpass the tweets at 4000Hz or something weird like that. i need to figure out exactly how this thing works. if they labeled the inputs high/low/sub instead of front/rear/sub it would be much clearer //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif. the outputs, however, ARE labeled front/high, rear/mid, sub; so perhaps i am supposed to use the front for the tweets and the rear for the mids...

also, it looks like the 10X only applies to the tweet highpass, especially because the woofer lowpass already ranges from 500-4000Hz.

and lastly theres a "parallel" switch (on/off), whats that for? im guessing subs, but i dunno what it even does.

It works just like diagram on the unit itself. You set the tweeter high pass (high /front) and that output is for your tweeter (so 3200-4000hz). You set the woofer lowpass to around 3000-4000hz depending on what sounds best. Then you set the woofer highpass to 80hz...

 

Just make sure the switch is set at X10 and you will be fine

The way you explained it here is perfect.

 

Front= tweeters

Rear=Mids

also, it looks like the 10X only applies to the tweet highpass, especially because the woofer lowpass already ranges from 500-4000Hz.

You are correct

and lastly theres a "parallel" switch (on/off), whats that for? im guessing subs, but i dunno what it even does.

This is used if you only have one set of RCAs as the input.

ONE THING TO NOTE:

It looks like the sub output is taken from the rear input from the HU. If you plan on applying T/A to the mids and tweets, then use the sub output directly from the HU to the amp so Time alignment isn't applied to the sub channel...

Hope that helps //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

no theres actually a sub-in too but i wont be running my subs through this anyways

ok, so i think i got it now. but just to make 100% certain, i emailed memphis //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif no offense but im not risking f*cking these comps up again lol.

yup //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif man i hope my **** RCAs get here tomorrow. i cant wait any longer!

got the rcas today //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif i wanna put them in but memphis hasnt gotten back to me yet //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Just test it, get a dummy speaker or use your mids and highpass the fronts...that way if it is indeed lowpassed you wont damage anything...

If there is no bass or midrange then you have your highpass //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

also, how do you know what setting you have these on? they only have markings at the far left and far right positions. like the mid lowpass for exampl says 500/4000 and has 5 tick marks in between. and they claerly arent in 500Hz increments. i also tried turning the knobs and they dont "click". its a smooth turn. how the f*ck am i supposed to know what i got it set on?

Its not a perfect science, and it doesn't alive to be for an entry level install...
If the pot is linear, which it more than likely is, the range is 3500hz. 5 tick marks means six sections, so 3500/6= 583.3hz per tick...which means they are in the ball park of 550hz per increment...

Do the math //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Everyone should have dummy speakers! Then just use your mids...with the gains nice and low //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

**** using my mids! im not riskin them ever.

well the tick marks are evenly spaced execpt the far left and far right ones. theyre slightly further from the last tick mark. ugh! i dunno what to do.

i suppose for the tweet i could just be safe and crank it all the way to 4000Hz. that would be relatively close to the xover point anyways. but i really have no idea about the mid. wtf, why isnt memphis getting back to me? //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif

You are a little paranoid, which is understandable...but a woofer isnt going to magically blow up...the tweeter CAN, which is why I suggested using the woofer to test...
frankly, I don't see what the issue is. The inputs are labeled Front/Rear/Sub.. The outputs are labeled High(front), Mid (rear), low (sub) respectively...so by simple logic Front = high, etc...

How hard is that to understand //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif Crank the tweeter to 4k highpass and the woofer to 4k lowpass and call it a day...you probably won't hear the difference anyway with your "ear problem" and all...

lol well assuming only makes an *** out of me and you //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif it would just make sense that if this xover was only designed to run 1 set of components (as youre saying) they would have labeled the inputs high/mid/low instead.

It has dual purposes...it can either run two high passes to front and rear fill (2 way) or front components (tweeter/woofer) and sub woofer (3 way)
Thats why its labeled Front/High, etc for the outputs...
