I am looking to rebuild my Navi to a more SQ style set up. Im not wanting to try and win any Usaci SQ events but what a more true SQ style sound.The plan as of now is to replace the 2 Kicker L7 15s on 2 ZX1000.1s with 4 10 inch alpine type R's I will power them with around 1000 rms. I have yet to model the box yet so any input there would help weather to go ported or sealed as i hear i can have a pretty flat response with either. My main concern is with getting the front stage up to par. Right now I have Kicker RS65.2 components up front off a Kicker ZX150.2. I mounted the 6.5s driver in the stock location and tweeter also in the stock tweeter pod. I am going to need quite a bit more staging than that. The problems with this is the seats block most of any useable space on the doors to add extra drivers. My only real options are to try and add a 2nd set of components or at least a mid bass to the door, kick panels on the floor(not ideal for SQ i would think) and/or something mounted at the A-pillar. Im thinking something in the range of 1000 watts rms up front will be needed to set the stage correctly.
Mods to the vehical- 2 runs of 1/0, Xstatic model 2000 Batt under the hood, Xstatic 800 series batt rear, Xstatic power pac(35 farad cap w/ 600 series batt built in), Iraggi 260 amp alt, big 3 of course and around 300 sq foot of dynamat.
About the only thing i plan on keeping system wise is the Kenwood ddx812 head unit. as well as the mods above.
My main questions are with my sub choice and power. What can i do to try and get the front stage up to par, power wise and speaker wise? I know how to do loud. SPl is like second nature to me. Box design i have a really good grasp on. But going to a more true SQ stage i am...... Well lost to say the least.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."ca$ino wrote:

SQ = sound quality

Would 4 10s not be a good thing then? I can surely cut volume to them with EQ and deck settings. Also i think it would look way bigger/better. Yes i want a more true SQ sound but i will also be showing in car shows and using for demo. So the 4 subs set up in a nice enclosure/install fashion would be a hit i think. As well as it would be more linear than a single sub, which would be a good thing correct?

There is no way i can figure i could fit all those in the stock location which was a 6x8 opening. I can fit a 8 or 7 inch driver in the stock location though. the problem is that the seats are very close to the doors and would block anything i put rear of the stock location. The seats set very far forward and high on the doors. The tweeters have a seperate pod where the mirror is that i am using now. I could also fab a pod for a 3 to 4 inch on the a pillar if you think that could be ok or even a pod on the dash next to the a pillar.
Im taking it that the problem i face by having more seperation in the speakers is the time delay. Is this correct? Or is there more to it than that?
Yes, that'd be nice, but we DO live in the real world, with all of the physical space limitations inherent in solid forms, don't we? With a 3 or 4 inch mid, closely coupled to a nice, thin trim-ring tweeter, you'll be much happier with all blending you will be able to achieve... (And it'll be a smaller pod, to boot) I can think of no really good tweeter (OK, MAYBE the ScanSpeak Revelator - mmmmm Revelator... <drool> ) that'll get low enough to match to an eight, which, at it's low-pass frequency, WILL be already beaming even at Revelator high-pass capabilities... Also, at those frequencies, the power handling of the tweeter will be sorely compromised. If you already have the tweeters fabbed into mirror pods, all you have to worry about (and AFAIAC, this still isn't REALLY optimal - still too far apart) you then only have to fiddle in a mid-range! Your work is already half done!
Back to your reply opening - I was just saying four 10's might be overkill in a true SQ system. (I know... "overkill" from haemphyst?) Surface area is a good thing, yes, but are you really willing to give up that kind of volume? Wouldn't it be more impressive to use a single driver, and just rattle the fillings from your teeth with it? If you choose a really nice, high-efficiency (OK, respectable efficiency), high-power, long- throw, high-linearity woofer ala TCSounds/AudioPulse, I think you can be very happy with the results you will receive, in a well designed enclosure. Judges like originality, as well, and exotic enclosures CAN be worth points in shows. I'd never seen ANYWHERE a stuffed, iso-loaded TL... So that's what I wanted! Something never before seen... I love mine, and it IS impressive. REALLY good output, with subterranean extension... <dave smiles...> I get flat to the low 20's. My F3 is (IIRC) 19Hz! From one 10"! Output monster? Not hardly, but PLENTY loud enough for me!
That's all I have right now, but I think you should read my install thread, as well as this thread... Steven did a fantastic job with this one... He's a two-way guy; I still think three-way is the way, but I agree pretty much completely with that thread. He mentions the additional complexity of building a three-way system, but for me? It was EVER so worth it.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
