Really? The crossover in the HU is a more effective way of doing it?

I would have thought the amps would be better... especially since the HU only does 50, 63, 80, etc. but the amp is finer tuning... But I'll give it a shot. Only thing is I don't know how to change the slopes, it doesn't show on the HU, but I'll look it up

Thanks again man!

 

there should be a menu that lets you toggle from pass, -6, and -12. those are the slope. at least thats how it was on my 7800, and the way it was on my 880 before i went active.

the 880's options change big time when you set it up active. haha

 

and crossover points don't need to be THAT finely tuned. i doubt you would hear a difference between a 50hz low or high pass and a 55hz high or low pass. once you start going that crazy i think you'll be going a little nuts trying to find a difference.

i'd strongly suggest the points i mentioned. i went back and forth a lot and finally stuck with 63/12 for the comps and 50/12 for the sub.

the somewhat shallow 12db slopes make it blend pretty well when gapped like so.

 

Yea I'm thinking about looking into a new HU with more tuning in the future if this one doesn't quite do it for me. Perhaps an 880 if i hear a lot of good things, but I probably won't be able to afford it until the summer at least, so I'll just deal lol.

I need to get these xovers straight though...i'm looking all over the net for it :-)

 

do you have the owners manual for your head unit?

maybe try that.

 

i found this on crutchfield.com

High Pass Filter: If you do not want low frequency sounds to play from the front or rear speaker outputs, you can turn on the 12dB/octave High Pass Filter. The HPF has a selectable cutoff frequency (50, 63, 80, 100, or 125 Hz). Only frequencies higher than those in the selected range are output through the speakers.

Subwoofer Output: The unit has a pair of dedicated non-fading RCA subwoofer outputs with a low-pass filter, phase adjustment, and output level. When the subwoofer output is turned on, you can select the frequency of the 18dB/octave low pass filter (50, 63, 80, 100, or 125 Hz), select the subwoofer phase (normal/reverse), and the subwoofer gain (+6 to -24).

 

Yea I know that's what the manual says, but the website has 0/-6/-12 for the HPF and 0/-6/-12/-18 for the LPF. Seems to be a mismatch of information :-\

Damn...looks like I'll just need to used the amps or something :-\

 

^ why? i'm a little confused. use the 12db or 18db slopes that the head unit has. toggle through the menu and i think you'll figure it out pretty quickly. it's just much nicer to control everything right at your fingertips right from the drivers seat.

 

Yea this is true...so just turn off the filters on the amps and use the HU only?

I just liked the precision of the amps... but I'll just turn of the xovers on them when I fix my gains.

Tcguy....what would I do without you to help me out lol

I'd have a power akoustic POS amp and a pyle sub or something lol

Actually that's a lie cuz I research before I buy, but still, you've helped me from the very beginning!

 

it's no problem man. i like helping people with car audio. you'll also have no problems with using the amps crossovers either. just use one or the other. def don't use both. i just like having everything right at my fingertips. i don't really have a choice anyway, now that i'm running active.

 

Yea I thought it would be nice to go fully HU controlled, but I wanted the precision tuning of the amp, but it's no biggy. I just had this idea that the amps would be better filters lol...dunno why...guess it's cuz they're closer to the final signal output, that's just how i rationalized it haha

I'll fix it up tomorrow :-) Do you adjust your gains seperately by turning off the mids to do the sub and turning off the sub to do the mids/highs? OR do you just wing it and do what sounds best to your ears? I wanna maximize signal-to-noise but it's harder to detect distortion when the sub is pounding :-\

Ehh, whatever, I'll figure it out lol

 

set the fronts with the sub off. then turn the fronts back on and turn the sub up until it sounds as loud as you need. that seems like the best way.

you can always go back there with a dmm and put it to the speaker terminals on the amp to see what kind of voltage the speakers and sub are actually seeing, just to be sure your aren't over driving anything. there is a formula to convert a/c voltage and ohms to watts. but honesty with your setup and what it seems your after you'll be fine. i don't see you pushing either the sub amp or comp amp to it's limits.

 

Oh yea I really doubt I'll push the limits on the amps lol... the sub would have to be jumping out of the box at 600 watts... I'm more worried about the RSD's handling it, but they seem to be holding well now that I'm not putting as much low frequency to them

 

yea the sub will get plenty loud before you push anywhere near the 600 watts you have to it.

the rsd's will also get plenty loud w/o using a full 150 watts per side. i beat the **** out of my rsd's cause honestly for $90 i could care less. but they take it fine. i have never heard them complain. no bottoming out, no smell of burning coils, nothing. the only problem i have when i really drive them is that my plastic door skins rattle/resonate a bit on certain songs. i need to deaden them some more.

i am a tiny bit worried about the tweeters. i am just not 100% sure on my crossover points, and i keep worrying about the head unit's amp giving them dirty clipped power at insane volumes. i am sure i am just being overly cautious though i think. they sound perfectly fine so i really should stop worrying. lol. active is just new to me.

 

Yea I understand, but really, if you blow the tweets, but a nice new pair that can handle anything you put to them... and if you're too worried about clean power, pick up a cheap 50wx2 amp... you could probably run it off an 8awg lead and mount it right in the glovebox or something... just a thought.

 

i have plans for what's next. for now i'll be careful with it the way it is, but i do plan to get a ZX200.2 and probably just hide it in the back right corner under the trunk floor in that nice big storage area.

 

Yea it's really an awesome spot for them...wait til I send you pix of my setup tomorrow. I'm getting my dad's nikon D-SLR so it'll be niiiiiiice.

For a first timer, I'm actually REALLY impressed with my install... though it was kind of a bitc h to figure out this amp cutting out thing, it all ended up really nice

 

yea i deff want pics of the whole thing. make a new thread with pics and stuff.

i knew it had to be something stupid and simple. glad you figured it out and got it all going. keep listening and tweaking and you'll be even happier.

do you listen to any rock or metal? i got a song you can play that will really give that sub a workout and show you what it's capable of.

 

Yea man I'm all about rock. Metal a little less, but I'll still listen to it on occasion. I just went over my friends house this afternoon and pumped some sabbath, slayer, children of bodom, and infected mushroom. If you've never heard infected mushroom, download that ASAP! lol... it's like daft punk mixed with shadows fall or all that remains... it's nasty bass heavy too **devil**

And yea i've put the sub through a good workout with the time I've put on it.. The bourne identity theme song is crazy bass heavy and i played that through it...shook my whole car and took my breath away when it dropped... add some chevelle and tool...it was bumpin lol

 

ok cool. i'll check that one band out.

have you ever heard of Trivium? get the song called "If I Could Collapse The Masses" off of the cd Ember to Inferno. i have never heard double bass so fast, and loud but still sound so clean. it really slams me in the gut. i just picked up this CD yesterday and it sounds sick on my setup so it should sound close on yours.
