Hi everybody ,
I have not been happy with my mb quart splits ive tryed a few different things to get them to sound better but still not happy with the sound .In my quest for good sq ive been to a lot of audio stores and rang even more but i only go to one now .The audio store i go to has said oz audio matrix elite are a great set of speakers so ive been asking for a while now at the audio store to contact the aus rep to get me some prices on 180cs older model and the new ones and some 380cs but havnt had much luck .At the last vic sq comp i finally heard sierra car and was totally blown away by the sound so i stepped up my calling to audio store to find when i can get some oz audio splits any way after a few calls over the last week ive been told they may be dropping oz audio from there line up .I have been offered a set oz audio matrix elite 3 ways for cost but they dont have crossovers audio store is trying to source crossovers for me direct from oz audio but not sure how that will go . I will go active if i cant source crossovers this is where i need some help pls
1 Will my cda 9887 control an alpine pxa-h701 processer or do i need rux-c701 to control it .
2 Will the pxa-h701 give me the opitions i need to run 3 way active etc4 sets of rcas
3 In what configuration would you guys run amps i have etc tweeter amp and so on
The amps i have
audiosystem f4 600 4x145 or 2x460 both at 4ohms
2x arc audio 1500 xxk 2x240 or 1x900 both at 4ohms one will run subs most likely
arc audio 2100 xxk 2x100 or 1x360 both at 4ohms

2 things mate..
1. You have more than enough amp channels to do any combination that you like
2. What makes you think that just because sierras car rocks ( and it does, trust me) that yours will sound the same?

Speakers are funny things, its a 3D world and most advice you get for tuning will be based on 2D "theory"

If you have a 9887, you dont "need" a PXA, the 9887 will cover the basics.

If you have experimented will a few speaker combos, HU combo's, etc, and feel that you need more from your tuning package, or indeed, that you NEED more tuning tools, go with the PXA, but until you have exhausted all options before that, (and most importantly, speaker choice), you need not be considering the PXA. It wont make your drreams come true, and can in fact, in the wrong hands, actually detract from a system rather than add to it.

Now Im not saying you dont have the experience, or tech savvy to benefit from the PXA, but if you still making speaker choices, you may well benefit from concentratrating on that aspect, well before you delve into DSP, or digital signal processing, experience the most influental component of any audio system first, and to its extreme, and that is speaker choice. all else is either install, or processing...

just some food for thought on your Journey.

i dont expect my car to sound the same as sierra car even no its a ef fairmont ghai virtualy same car i have different amps , different hud , two g5s and am looking at oz audio 3 ways so i dont think it will sound the same .I didnt think the cda 9887 could run a fully active 3 way system with sub because even in 3 way mode you have
low range lpf 20hz-200hz
mid range hpf 20hz-200hz lpf 20hz-200khz
high range hpf 1khz-20khz
So i thought low is for sub mid could be for mid range or woofer and high for tweets so dont i need another range so i can do mids or woofer thats why im thinking pxa i was all so told from audio store i would need pxa to run 3 way plus sub and i will get store to help me tune pxa if i buy i know they know what there doing

The 701 caters for an active 3-way setup. I use one myself.

Even with all those brilliant amps; I found that the biggest improvement in sound is going from a dodgy speaker installation to a good one. Its all about testing locations, adjusting the gains right then final tune using the processor. In a test environment, its no good having your speakers angled correctly playing free-air either. Mock up some temporary enclosures. As for speaker choice... You cant go wrong with a reputable speaker set, it always helps to listen to them in a car first. Anyway. So if your happy to fork out the bling, go active and set upon the frustrating challenge of getting it right... do it.

im not sure what the x-over settings on the 9887 are since i have yet to play with them. I assumed they would be the same as the old bass engine pro that came with my 7998 and the good old 9855 headunits which from memory had more settings on x-over than what you have mentioned above.

if you want higher midbass than 200hz (are you sure thats all it will do?) then you could run passive mid and tweeter from the high/tweeter output then run midbass from the mid outputs then sub off the sub output. So fully 3way active with passives on the tweeter high rca output.

semi active can work quite well and sound extremely good. This is best done with matched tweeter and mid sets that already come with passive x-overs.

h701 will easily do 4way active the way you want. IM not sure how the imprint software will work with this setup...i assume it can still do it (which would render the eq in the h701 useless). Anyway lots to think about, oh the choices.

pages 14-15 + 22 in users manual i did find it eventually

its not as good as bass engine pro...which is dissapointing

low/mid-L 20hz -200hz (so for you sub out)
mid-h 20hz-20khz banpass HPF 20hz- 200hz LPF 20hz-20Khz (midbass)
high 20hz-20khz (so you can use passive tweeter mid setup)

4way active is nice enough to run, the fun part is finding out the right tuning for it

How can i use passive for tweeter mid if i wont have oz audio crossovers so how can i run them passive .What do you guys think , im either going to run amps in either of 2 configurations

A
audiosystem f4 600 bridged 460 x2 woofer
arc audio 1500 xxk 240x2 midrange
arc audio 2100 xxk 100x2 tweeter
arc audio 1500 xxk 900x1 subs

B
arc audio 1500xxk 240x2 woofer
f4 600 145x4 midrange & tweeter
arc audio 1500xxk 1x900 subs

I am not realy to keen on using imprint in new setup i have the imprint box so i can hook up to pc and have done so a few times .But too me it always sounds better with manual tune than with imprint box just my 2 cents

(Will my cda 9887 control an alpine pxa-h701 processer or do i need rux-c701 to control it .)quote from first post.
I talked to audio store today which has talked to alpine for me and said my cda 9887 will control pxa-h701 but will be a bit of headache so i ordered a pxa-h701 and rux-c701 today got a good price too .I will also be picking up some oz audio matrix elite 3ways in the next couple of weeks and then the fun begins .Not sure if should start new thread or not but i have another question i have one run of 0g stinger too a fused distro which has two 0g inlets and four 4g outlets if i use all of the outlets for four amps should i run another run of 0g .
2 x 1500 xxk 120 amps max each
2100 xxk 42 amps max this one only needs 8g according to manual
f4 600 120 amps max
thx for your help guys :clapping:

I'd run a second run. It may not be necessary, but it will most likely be a bit better to ease the load on each length of wire. You could probably just use 4gauge for the tweets/midrange amp, and 0 gauge for the midwoofer and sub amp. But dual runs of 0 gauge will look better

Thx louie now to figure where im going to run a second 0g run through firewall the fun games are starting

[xwfalcon]

Another quick question pls guys I would like to know if i have to run the rux-c701 control unit hooked to pxa all the time or can you set pxa with control unit then unplug control unit .I got my pxa and rux the other week but have had a bit of set back as ive bought another amp couldnt help myself so the audio systems out and now i have a brax coming so looks like another couple of weeks before i can pick up my speakers.
cheers xwfalcon

[Pulse-R]

you can unplug the control unit, and it will continue with current settings.

make sure it's powered off before you unplug it though!!!

[xwfalcon]

Thx pulsar-r i will run controller cable for rux in the glove box so i can pull it out to drivers seat and when finished put rux back inside the house .
