Some Questons On Running A System...

[JBass64]

Hello,

I've recently bought a 1995 3000GT Base Model, I just joined this forum today, so I'm introducing myself along with a few questions. One of my main concerns with my GT is the zero trunk space im given. Im a very big fan of systems and that was my first obligation on this project. I have seen some of the ideas that you all have done but I just have a few concerns. Okay, well I've seen 2 pretty cool ideas for boxes. One box fits flush inside the rear seat and fits right behind the wheel well. I understand that you need to get rid of or move the CD Changer, thats not a problem. But from what Ive seen the most you can run is 2 10'' speakers. And i wanted to run atleast 2 12's. The other box that Ive seen runs flush with the trunk lid that covers your spare tire. My concern with this was that I would possibly have to get rid of my spare tire which I dont want to do. Also with facing the subs upward, I dont know if I will be running the risk of blowing my rear window. I'm not looking to do anthing fancy, I just want quality and a good sound, But I also want to keep that cover that hides everything in the trunk...YES....I KNOW...I'm pretty picky with this, I just was wondering if there our other paranoid people out there like me who may have solved this problem...ANY help is greatly appreciated...Thanks!

in keeping the trunk cover, you will never be able to push enough power/airspace to hurt your back glass.

regarding your back glass, I am hitting an SPL of ~150dB give or take and I have not hurt my glass at all. you're fine.

advice section:

don't fire your subs upwards, they won't sound as crisp or as deep as if you fire them facing towards the rear of the car or parallel to the glass. this will give you the best response.

if you are wanting shear SPL and not so much sound quality, you are going to have to give in somewhere...either with your back seat or your spare or both. SPL takes airspace...any large sub is going to take TONS of airspace. if you go sealed boxes, you won't have the SPL that it sounds like you want and your subs won't have the deep response that most people are after...

soundproof your car or you are going to go nuts with all of the squeaks and rattles that accompany any system. two bulk packs of dynamat will run you ~$300.00 or so...it's worth it.

go QUALITY amplification and QUALITY speakers and QUALITY subs and QUALITY head unit. so many people try to do a "big" system and scrimp and save when it comes to equipment. they pay someone an assload of money to do fiberglass work and then put shitty equipment in. looks great, sounds like pooh...

Old Set Up in my old stealth, still in that car




Current...no spare...still have cargo cover

2-Seat Conversion... then you can fit your 12's in easy! those back seats are worthless anyways!

smokinvr4 has several designs for duel sub boxes. I'd link you to his new site, but it's under construction and the box pictures aren't up yet.

Thanks alot for all of the help, I'm getting a better idea of what to do...I do understand that facing the subs up will not give you the best of sound, So i think I can scratch that idea, but I also know that the closer the subs are to the trunk, the better the sound, my concern with the box that fits in the area between the back of the seat and the wheel wells is it may be to far away and may sound off...And i also want at least two 12's...But I have seen some of smokinvr4's work, does he sell any of it? or is it just his personal boxes just sharing ideas? Im sure I can manage to make somethin myself, my uncle has a lot of experience with this...I'll just have to look up a thread smokinvr4 has written if he has one for ideas...Thanks again for all of the help, any other ideas will be greatly appreciated.

stealthawd, thanks for takin the time to give me all that info

[stealthawd]

no problem at all man...that's what we are here for

it isn't so much that the area between the back seats is too far away (this is actually where my sub(s) reside. keep in mind that low frequencies are omnidirectional and time alignment isn't so much an issue in a car as it is in a large theater. xwire actually has his two 12's in the back of his car about 6" away from the rear end...but he did extensive modification to his spare tire well in addition to removing it altogether. there is a thread that someone just posted a 15" Eclipse sub for sale since you mentioned considering a 15.

[JBass64]

I see, quick question....Through talking to you and others on the forum along with my brother whos gonna be helpin me on this project, He said that in the end, I'm gonna have to pretty much choose, bass or voice...Considering I listen to a lot of classic rock but some rap as well, I thought of using that box that fits behind the seat w/ 2 10's with 2 EV's for voice (or any other voice sub), then running a single 12 with that box that bnorris85 posted on this thread for bass? My brother kinda looked at me like I was crazy, and I do need trunk space, along with access to my trunk for little things but, I never realized how difficult this car was gonna be lol...I thought it was gonna be an easy nicely built box for 2 12's and that was the end of it. The good thing about this setup is I keep my rear seat and my spare with easy access to it lol....Another concern is the two 10's will be facing towards the trunk and the 12 would face up...Would this interfere in any way? or should I scratch all of this and just go with two really nice 10's that push a decent amount? I'm not looking to blow people away, but I like top of the line for systems, I have subs and all that picked out, EV's were just an example for voice...But i have a feeling that setup may not be the best...Again thanks for everything lol...

[stealthawd]

you are making it way over complicated...much more than necessary. my system is crystal clear but hits hard when I choose. I listen to all types of music and if there is rap or techno in my system, you definitely know it. if you want good definition to go along with your nice deep bass, just get REALLY good components and REALLY good amps and a super nice HU pushing at LEAST 5 volts...preferably 8 volts.

you don't need multiple size subs in your car and honestly, one 12 setup right will make you not be able to sit in your car. I am running one single 12 and my car can literally make your eyeballs vibrate. it's all about placement and power and amplifier headroom...

[JBass64]

lol figured I was goin a bit overboard...I think I got it now, pretty good idea of what I'm gonna do...Components are definantly gonna be a first..I was thinkin either some MB Quartz or Diamond Audio along with a nice deck and power them by a separate amp...And ill probably end up runnin either one 12 or 2 10's...Thanks so much for all the help bro, you did more than enough, I think I can take it from here...Didnt think this forum was gonna be as good as it was...thanks again!!!

Diamond Audio is definitely a great choice. I was running M6's before I switched to Bravox which is what I have now. No complaints with them at all. They sound awesome.

Good luck with the system and keep us informed. If you need any info on Diamond Audio or anything along those lines, just holler. My buddy is a Diamond dealer as well as Eclipse, MA, Bravox and tons of other stuff.

Q2: when i export forms to 3dsmaxallways .3ds, some of the surfaces are backwarded and i have to flip the normals of the faces.
how can i escape this task?

Fuck you.

My first question would be why do you want to run's 12's over 10's?Just get a set of top dollar 10's and a Top dollar amp,Top dollar door speakers frnt/back and a a top dollar head unit...2 10's in a 3kgt is perfect.Like Stalthawd said don't go cheap cause u get what you pay for with Electronics.I have a Sick little system with one 10" sub Alpine everything...I can still hear the words but it rocks your back.I don't know I guess I just go for a quality...Either way 10's

Go to an audio shop and listen to a 10" sub on specific song. Then about half way through the song switch to a 12" sub that is the exact same brand and model. You also have to make sure the subs are mounted in identicle enclosure types, i.e. both ported or both sealed or whatever so long as its not a bandpass box. What you will notice is that the characteristic sound of the 12" woofer is deeper than the 10". This is due to the sheer physics of moving air with a larger surface area.

The way I used to describe the difference between a 10" and 12" woofer to customers is that a 10" woofer is good for tone drop/transition while a 12" woofer is good low punchy bass.

There is no "one is much better than the other solution" since they physically can't sound the same. So a person needs to pick their sub size based on what they want from its sound. IMO the only 10" sub I would bother with is a Kicker L5 or L7 since their increased surface area does split the difference in characteristic tone.
