2nd Generation Eclipse System set-up?

[white92talontsi]

Yeah but a lot people who want to "throw some 18s in this bi***," rarely care about the rest of the setup. I've seen too many people running subs on stock speakers. Upgrade the speakers first then worry about the bass in my opinion.

Agreed.

Anyway to the OP.

If you pick your sub correctly, and you design a box built for that particular sub then it does not take much to get loud.
It's not as simple as buying a sub and throwing a box together and then when it sound's like ass or wont hit the low notes and calling it crap. 90% is in the enclosure with the other 10% being the sub.

I dont know how much room you have to spare or you are willing to lose but if you have a shop that can build you a transmission line enclosure I would go that route.

I started building my own T-line enclosure's and I will tell you it is one of the best design's out there. As was stated earlier efficiency is key to a subwoofer setup. Ported enclosure's are more efficient then sealed enclosures but sealed enclosure's generally produce a tighter bass.

Well the T-line kind of crosses this path and merges the two together. So not only do you get tight bass but you also get a broader frequency range that you would with a ported enclosure.

Here is my self built enclosure that i built around a HDC315. Box is 3.5 cubes tuned at 35hz. I tune low due to the fact that if you play lower than box tuning then you start to heat the voice coil rather quickly and also playing below port tuning you will start to free-air the sub and bottom it out.
This setup was run by me for 2 year's on a single sundown saz-1500d wired to 0.5 ohms which saw the sub seeing roughly 1900-2000 RMS daily.

Now I ran this setup in a trunk car. So something like this would be alot louder in a Eclipse. Even in the trunk of my car I could "Flex" the front windshield a good inch. It never broke though

If you know a good box builder this "is" the box to have. You will sacrifice alot of room though. This particular box being 3/4" MDF weighs 76 lbs.


Here's a straight ported box designed for 2 DD9515's

How did you not see or hear or notice your spoiler was loose? That couldn't have happened in a day.

I never opened the hatch, it didn't make any noise that you could hear over the music. Couldnt tell it was loose

Here's my trunk. Sorry for the cell phone picture. It is one 10" Boston Acoustics subwoofer powered by the Alpine amplifier, the Hertz amplifier is for my front 6.5's. There are two faceplates that sit on top of the subwoofer box (one black suede, and the purple vinyl) that allow for easy access to all the equipment. This was the only efficient method I could decide would cleanly hide the mess underneath.

This setup on the 500 watts did 138.9db, so its fairly loud. Loud enough to flex my back window a bit, so maybe you don't necessarily need the 15, just an idea. Sorry for all the jargon, here's the pic:

ok I thought about doing a set-up like this but I would be fiberglassing it and i seen a problem in this set-up.
What if you had a tail light out?



Right now I just got one Memphis 12" in my eclipse getting about 150 RMS when the RMS power is 250 on the sub and I will admit it can get loud. And I love this sub because it is such a clean bass and very responsive. My girlfriend has 2 MTX subs getting all the power they can get and she is mad because my one memphis is louder than hers.
I know the eclipse don't need many subs cause this one is way louder in this car than it was in my truck. But the reason I am getting the 15" is because you can tell the 12" picks up great mids and lows but the really low lows it has a problem.

I know the subs will be facing the back rather than up or to the front. We moved mine to face ever direction to see when it got louder and facing back was the best.

I seen those videos on youtube and I was surprised but i want a clean sound more than a loud sound and I don't want to tear apart my Eclipse I wish I had the money to

 

[white92talontsi]

Those videos I posted, you would be surprised to know that even though its tearing the car apart it is very very clean sounding.

The TC Sounds LMS Ultra 5400 is actually designed for home theater setup. Its not designed to be extremely loud. It is designed mostly for sound quality and be able to go lower than any sub on the market, hence the LMS(linear motor structure).

It is truly an amazing sounding sub. Cost is 899 for the 18".

That is a tray that drops in. It's not permanently bonded to the car's interior panels.

What is your purpose for this system? If you just want a good sounding system for daily use, scrap the 3 sub idea. Mixing sizes makes it extremely hard to design and tune an enclosure. Just do as everyone else suggested and go with 1 or 2 subs in a quality enclosure and give them adequate power. Everyone goes through the phase of wanting to just throw a bunch of subs in his car and run an insanely powerful system when they aren't experienced with car audio. Do a smaller system right and it will not only be just as loud, but it will sound much better.

I'v been working with systems for over 8 years now. So I have the experience and I'm not just throwing subs in my car. I picked out great responding subs and have great amps that are underpowered to the subs (hint best set-up cause its harder to blow a sub if its not getting enough power to over do it). Mixing subs sizes yeah are harder but when you do it right it sounds great the 12"s can not pick up the deep lows and the 15" will get most of whats left sounding great because your not missing anything. My car is going to be a daily driver and I still want all the use out of it. Why I am keeping the back seats so just in case one of my legless friends need a ride they can fit back there also I am fiber-glassing the three boxes i build together so it will be easier to tun the boxes to sound right if its three different boxes.

I don't understand why people come into forms and just dog what your going to do. I understand asking questions like why. But tell me to not do it and just go plan and simple. why, i want there to be something different in my car and just because someone can't do something don't make everyone not do it and no this isn't completely to Zdrummer but it happens to many people out there.

So back to the forms anybody have any ideas they want to throw at me with the 3 subs that are staying

 

[white92talontsi]

Hate to rain on your parade but a 15 being able to play lower than a 12 is a myth. Same goes for 10's etc etc...

The size of the sub has nothing to do with how "low" it can play. The design of the speaker dictates the frequency range and the enclosure design are what are the factors.

Now they wont be as loud at the lower notes due to the fact that the smaller the speaker the less cone area therefore the less air it will move but they will all no matter what size be able to hit the low notes just the same.

Thats why I am getting the 15 to pick up the lows better the 12" are getting them but struggle. I know from personal experience hooking up the same system because that is what my brother got and then he added the 15 and the lows got louder. Yeah adding a bigger cone to the same driver doesn't do better it needs a new driver.

No ideas for the sub enclosure but one idea would be an english class...

 

[98dsmkid]

stick with 2 10" subs.....(I'm not hating) but IMO I think that set up is to much noise...too much attention! and jz unessesary....

When you changed to the 15 you also changed enclosures.
So the system was not the same.

so instead of blowing the subs from having the correct amount of power, your gonna burn out your amp by overworking it? this doesn't sound like a "best system set up" to me...

 

[white92talontsi]

I hate to say it but you don't know as much as you may think.
1st never mix sub sizes.
2nd running too small of an amp and clipping your subs will kill it faster than running a amp rated for more power than your sub.

Clipping the signal to the amp or clipping the signal to the sub are the number 1 killers of blown shit.

Amplifier headroom is a plus.

Wow, one English is my best subject, right next to math. Sorry I don't right in perfect English on a forum site when I'm in a rush. And to add to the point that I am also dyslexic, so that does effect it, but come on it's a forum not a paper. Most forum sites, if they have a problem just highlight your mistakes in red. Anyways, I don't care about my English on here to the point where i have to proof read it and outline and all the lovely steps needed to right a paper. You can read it, sorry i don't dot my (i)s and cross my (t)s.

But an under powered amp is how I have always done it with the proper tuning and my brothers 7 year old system still works just great to this day. 160 watts RMS bridged to a 250 watt Rms Sub, with the right tuning and it's been great. And in his other car we didn't change the 12"s to a !5" we added a 15" to the systems so the 12"s are still there. I have picked out and hooked up over 20 different systems for all my friends and all are the same set-up and all work great. My girlfriend got her system done professionally before I knew her and it's messes up all the time and has been through 2 head units and 3 subs and 1 amp. The subs have blown due to the amp having more power than needed. The first amp. burnt out. And well, the head unit she has just sucks. Oh not to add she has mixed sizes to pic up different frequency ranges. You have tweeters (1") door speakers (6 1/5") (6"x9") dash speakers (4") they are all different sizes but yet sound great when you tune them right. You can't just throw them in and go. You do the math and get the amps. that the speaker needs the amp. to put out and then get a frequency cd and turn the radio to the loudest volume you would play at (never over 2/3 of the max) hook a meter up to the speaker outputs on the amp and tune the amp. to the number you got earlier and there you go it will never blow any time soon.

That is complete and utter BS. Do you understand the Pressure level that it take's to crack a windshield?? Look at the video's I posted. It takes that kind of power and SPL to bust a windshield.

Woah there buddy calm the f down. I had a small crack in my windshield in the bottom right corner and within a few days after installing my system the crack had spread throughout the whole windshield. My apologies for not making that more clear.

 

[jmitch]

White92talontsi it telling him the right info. To OP what kinda sound are u looking, if u send me the measurement of the space youre wanting to use and the equipment youre gonna use i can help u get started.

 

[bryceorbiter]

I have a thread that show my custom box running two tens and a fifteen, its a lot of fun work to make but once we got it ported right it sounds killer.

Also mixing sub sizes is fine if you set it up right, i sealed my 15 and ported my 10s and it sounds perfect. Just a bit of tuning to get it to sound right and make sure that you use separate chambers for each sub.
