I have posted this thread in the Audio Forum, but I thought that it may be missed by some 5th Gen owners who could be interested. On my web page I have detailed sketches, measurements and instructions on building a similiar setup to what I am installing into my 2002 SE. As some mentioned to me, they would be interested in the design, which is why I am posting this on the 5th Gen Forum as well. Hope it helps if you are looking for some design ideas for your stereo setup in your 5th Gen. My site has pics on page 3 of the enclosure and sketches, demensions, and instructions on page 4.

Good luck all you "crafty-craftsman" <- from "Meet the Parents"

 

cool.......

 

Great info for a custom box!!

 

I can't wait to make a version of it. Thanks for all your hard work and willingness to share. That is what makes maxima.org great.

 

Why did you initially use particle board?

 

Nice, and you still have trunk space!

The three 8's you are using will absolutely ROCK!

I love my 12W6, it absolutely pounds!!!

 

As I mentioned in the initial post in the Audio Forum, using another material didn't even cross my mind when I began this process. But afterwards, I can see just how much higher quality the enclosure seems by using the MDF. Thanks for all the positive response, and for those who will be attempting to create a similar setup in their cars, please feel free to add me to your AIM list "trtsc1975" and I'll be happy to help out as much as I can, or just shoot me a "pm". Thanks again.

Gotcha....

You ever considered having the subs rear firing? Front firing subs don't sound nearly as good if you put the seats back up.

 

You have a PM.

 

I wanna know

 

Sorry to leave anyone out of the loop. Having these fire into the cabin of the car will be sufficient for me as I'm not attempting to win any SPL contests which is also why I have 8 inch subs vs. 10's or 12's. I can always lay down the rear seats to make it louder, but doubt that will be the case. Obviously, this design, as any other, if you choose to duplicate it, can be altered to your liking.

 

nice, but i really don't think particle board was a very smart idea...

I wonder what 3 8w6s feel like

 

They push enough air that it would move my hair in my old car, and that box was made out of MDF eveyone! lol

 

Kpazzo!! For Gods sake, give me your car!!!

 

First off I am not trying to dis anything you have done because I like the idea. OK, thats out of the way . I have a question... Did you build this box to the specs of the speakers or to the car? Or to both? The way a speaker sounds has a lot to do with the box. Supposed to have the right air flow/volume and other crap like that to get the best out of your speakers. I am not going to go into detail because I do not know that much about it. I am just wondering if you built the box to your speakers specs. So if someone wanted to build that same type of box for 10's or 12's maybe, that the circles for the speakers would obviously change... but the dimensions of the box will as well. To accomodate the bigger speaker. Also, different namebrand speakers reguire different specs as well, so what fits JL 8's, may not work for Rockford or Diamond... Just curious I guess for future ideas

Send him a PM and let him know how much you like his car.

 

Dennis, thanks for the input and questions. Yes, I am aware that in designing an enclosure for subs, you have to take into consideration the recommended specs given by the manufacturer of the the loud speakers. I had these 3 8's in my last car and that box was built to JL Audio specs for a ported design and it sounded very good. With the previous box demensions in mind, I built this box which overall is pretty close in demensions. Obviously, there are a few differences, but from what JL recommends, in this application for 3 8W6's running in 4 ohm mono which my amp will be bridged at powering them at a rated 350 watts + by MTX, this setup will work fine for me. Like I have said previously, for anyone who is interested in using this design for either their 10's or 12's, it ultimately comes down to your individual speaker manufacturer specs and any customization of my design to fit your application. Hope this helps to answer some of your and maybe some others' questions.

Keep 'em coming.

 

Thanks for the quick response and for the good explanation, Now when you gonna build a box for that bike

 

Soon as I find a place to mount a 7" LCD screen.

 

im just curious about something. since rear firing subs are louder, wouldnt it take less wattage to make as much sound if you had rear firing instead of front firing? Since it would take less wattage, wouldnt that be better for the system, amp, speaker, etc to make it rear firing? i honestly have no idea, but i am interested

 

Well, in this case with me using JL Audio subs...they are pretty much wattage-sponges. They take alot either way, so with them facing the front/cabin of the car, I think they will work just fine for what I'm hoping to accomplish. Hope that answers your question at least somewhat.

 

but would it be louder and take less wattage IF you made it rear facing?

 

Didn't want you guys to think that I didn't answer SXN's question. Spoke with him via AIM.

 

and you were incredibly helpful at that

 

I got off work Wednesday morning and began working on my install. I am about 90% completed at this point and will get the final details finished tomorrow (on my birthday..woohoo) I have installed a component set from JL Audio XR650-CSi for the front doors and the JL Audio VR600-CXi coaxials for the rears. I am not upgrading the head unit at this time, so with a four channel and a two channel amp, I've had to use two Stinger high level to RCA converters and almost 50' of Monster Cable. I have taken many pics so far and will need to get them developed and scanned prior to posting them (still hoping for my digital camera for my b-day). Currently all four door panels, all door sill pieces, all the seats and all of the trunk pieces are removed from my car, pretty much taking up the entire other side of my garage. I'm anxious to see how my 3 JL 8w6's are going to sound along with the mixure of new midrange speakers. Thanks to all those who have contributed ideas and suggestions (MDF, MDF, MDF) You guys/gals will be the first (other than myself) that will know how it turned out.

 

I had pretty much the same style box with 2 Infinity Kappa Perfects facing into the rear seats. The bass was really tight but nowhere near as much bass compared to when they were rear facing. I now have them rear facing again.

The measurements you posted are great btw!

 

Thanks, I know that asu174 used some of the design for his box and faced his sub into the trunk. I'm sure enough volume will be created from this setup that I'll be pleased.

 

happy early birthday man, hopefully you get a camera, and hook us up with some pictures

 

Happy B-Day bro. Hope all goes well.

 

whats the weight on that bad boy? any idea?

 

The install was completed on Monday and I just updated my webpage with a bunch of pics. I have one of the new JMS Products Upper Grille that I picked up on the GD thanks to studman. Please check it out and see what you think. Don't forget to sign my guest book please...it looks pretty sad with only one vistor posting in there Any questions at all about the install, please feel free to ask away.

very nice are you overall happy with the box?

 

Looks good man, damnit I think im gonna end up wishing I had that much trunk space after the system in a week.

Dude, I know you used MDF but I still have to give you **** about the particle board

 

Very clean install!. I am very impressed!

 

Thanks guys. I appreciate all the compliments.

MannyNJ2k2max, sorry I hadn't answered you question yet...I'd say with the subs, the box weighs about 50-60lbs or so.

I owe a big thanks to everyone on...

 

Very nice set up.

are the tweets JL as well?

 

Yes, the front component set is the JL Audio XR650-CSi

 

All these comkments about which direction the subs are firing are a moot point. It is what it is. I think he was more concerned with aesthetics than performance. I am putting a single 10" in the back left corner just enough bump, and 95% of my trunk will still be free....
Nice write-up!

 

SEmy2k2go,

First of all, very sweet install. I myself would have also faced the woofers into the back seat. What you will lose in SPL, you may gain in SQ. Venting the woofers into the cabin will usually result in better articulation. And if it sounds loud enough for you, then all is well!! I myself am working on an aperiodic enclosure that will fire into the back seats using 2 Soundstream EXACT10s.

I bet the 3 8s sound very smooth.

I do have a question, though. Is there a reason you decided to have all three woofers in one common area rather than dividing them up into three separate chambers?

Tony

 

The box was complicated enough with the design as it was. I could have separated the subs individually, but in the previous enclosure I had for these three, they were all together and it sounded really good as well as it does now (don't fix it if it ain't broke I guess...lol) Plus, you can see from the following pic, that with the location of the subs being so close to each other to get the look of all three in the opening behind the seats, there doesn't appear to be enough space for a wall between each one. Hope that answers your question. Thanks for checking it out.
