Custom Sub Box in the GXP
 

so i got tired of this huge sub box that i have my in my trunk, so i decided to get rid of it

everytime i hit the highway i have to remove the box from my trunk, its really heavy and i have hard time moving it alone, and also good luck finding place to store it
i just paypal'd someone in the States to make me a custom box so i can get some more room back again

currently i have the amazing JL 10W7 with its JL made box

but it takes too much space for Bass i dont use

Attachment 20543

this is what i have ordered
Attachment 20544

and the amp will go on this side
Attachment 20545

hoping to have it here before i go away on Holidays in January
he said it could take a week or too, but with the holidays coming up god knows

if the box ur getting is exactly like the one pictured, its not compatible with ur W7. W7's require more volume than pictured. the sub pictured in that custom enclosure is a JL W1V2 i believe which have very small magnents. Someone correct me if im wrong and i hope i am.
By chance it is big enough u will loose ALOT of bass. those JL ProWedge boxes are made for max output. thats prolly 2.5 cu ft for one 10" sub and the new custom enclosure looks to be less than 1 cu ft.

and ur amp should be larger than the one pictured to so i dont know if it would fit in that little area.

Yes I am aware of all of that, the sub box will be stickiing out a little more and going in a little deeper to match the specs for the 10W7
As for the amp box/mounting bracket it'll be built based on the G-Max size, so I'm aware of all it
I barely bump my sub all the way up, whatever extra bass I have out of the JL box is not worth my trunk space that I'm losing
As long as I can have a little kick in the back of my seat, I'm happy.
But thanks for the info!

ok sounds good as long as the enclosure is a little bigger than pictured ull be ok. I believe the min box volume for a 10w7 is just over 1 cu ft.
I was just worried it wouldnt work at all.

yeah it is for sure, the guy told me its gonna stick out a little more, and its gonna be a sealed unit, any idea how much bass id be losing?

and whats cu ft? the volume?

yes cubic feet is the inside volume of a enclosure. but u gotta remember that the magnent/motor structure is big on a w7 so u also have to subtract that from the net vloume. U will loose quite a bit of output. U will be going from a High Output box specially made for your sub to a MUCH smaller enclosure. But we will have to wait and see.

As long as it still gives him some knock, who cares? Not everybody is going for earth shattering bass like you are.

Right I understand, He asked how much bass he will loose. And after sub displacement, if the box is less than 1 cu ft it will sound horrible, but if the guy he is buying it from is good and knows what kind of sub is going in it, im sure he will make the necessary adjustments.

makes sense, if i lose too much i'll just go back to the HO box, and here goes $400.00 down the drain... but i doubt i'd do that, all i need is a little bass for ME inside the car, i dont care for people outside. not to mention im only 22 and im hoping to keep my ears for atleast another 50 years lol

correct, little base is all i want, reason i bought what i have now is because i got the 10w7 with the JL GMAX, the box and the wiring kit

is that on a sealed box or ported? is there a difference?

I had my box custom made to fire through the door in the back seat. It is long and skinny so it hugs the back seat.

any better/bigger pictures than your sig?

lemme just jump in on Toms system for a min here..ive been building systems on and off for a good 3-4 years..and toms is the loudest SINGLE 12 in a sedan i have ever heard!!

but at the same time..its not overpowering and rattling your fillings loose

look great!!! you built it yourself?

is the sound system for sale :P

Nope, box was done by a friend of mine. It is a lot more intricate than it looks. Ported and sized to the exact specs of my sub, tuned to 35 hz.

I'd never be able to get my money back out of it if I tried to sell it. It's going to get moved over into the new car eventually unless by some miracle the SSEi gets fixed.

Is your box ported into the trunk with the sub firing forward? How does that sound? It seems like your trunk is pretty well sealed off with all those panels so I'm curious if you lose output because of that.

It's ported on the left side right behind the battery. The box is completely sealed off from the trunk. Makes for no trunk rattle and sounds great. I've never had anyone complain about it being too quiet : P

If for some reason it sounds like Hell let me know. I might buy it from you.

Ok. That makes sense. A lot of people on the audio forums do sub/port forward with the box sealed from the trunk. I thought about it but since my seats don't fold down I decided not to.

The reason I asked about the ports is because I saw what looked like ports in the trunk pics. But now that I actually think about it they are just cutouts for the trunk supports. Duh.

i got a msg from someone saying the new box might be somewhere around 1.25 cu ft, is that big enough? remember this is sealed
i heard sealed boxes take less space than ported

Just depends on the Sub Sam...

but it doesn't sound big enough

My seat doesn't fold down either, but there is a gap between the box and seat so as long as the little door is open it's all good. Even with it shut the it just dampens the sound a bit.

in general ported boxes need to be larger than sealed boxes. your sub in a sealed enclosure needs to have at least 1.25 cu ft AFTER sub displacement. Not saying it wont work. just thought i would bring it to your attention.

Again it depends on the sub.

You could go with a JLTW5 http://mobile.jlaudio.com/products_s...hp?page_id=245

I appreciate your help, I'll call them tomorrow or monday and see what's going on, I need the sub box for sure, I need the room, if the box can't fit the sub mostly I'll downgrade to a W6 or something else

What would you recommend? Size wise

if your worried about trunk space, why dont you just put two subs in your back dash, and enclose them and call it done ?

that would be the easiest route IMO!

you mean like Johns setup? mounted on the read deck next to the stock speakers?

never thought of going shallow, something to look into


EDIT: 600 RMS?! omg i liike!

that is a possibility. Its a little costly but if u were gonna spend $400 on that enclosure anyhow..... I think what u are trying to do can work. but spending $400 to find out it wont, that would be bad.

Im not a pro so i recommend talking to a couple pros. Get on SMD.com and call a couple GOOD audio shops and talk to em about what u have planned. I just dont know if ull have enough volume trying to stuff that beefy sub in the corner of the trunk like that

JL recommends 1.25 cu ft for the 10W7 on a sealed enclosure, and 1.5 for the ported one
im gonna call and check tomorrow, the W5 shallow might be an option

similar to that yes, what i was referring to is taking the stock deck lid and modifying it a little..

you could do something like this..except with two 10's or two 12's

http://forums.trinituner.com/upload/181_zoom4.jpg

that would save you alot of trunk space, and in the same aspect it could sound alot better than mounting ONE sub in the side of the trunk and the amp on the other

say if you put one sub on each side of the back dash where the stock speakers were supposed to sit then you can mount the amp between the two subs, and build a box that will cover said amp and subs

that way you can save your space, gain good sound and have a nice clean install, the only downside to this idea is that your going to loose some of your vocals and gain bass, but that can be fixed easily with some components up front

if i was in ur shoes sam id go this way over anything else, it seems to make the most sense, but im just trying to give you ideas

correct

Correct... to you Sam, not wakefield, lol

yeah i figured! lol its all good man!

those subs are mounted free air, weird

yepp, some subs you can get away with that, for instance say if there a ported sub to begin with..a trunk would work as a pretty good box

my buddy took a set of ported kicker comp 12's and mounted them on the back dash of his 97-03 GTP, then mounted the amp between them, and left it like that

sounded pretty damn good to me :D

I used to have a pair of old school 15" Kicker Free Air's But i doubt they would move enough air to be able to use the whole trunk as an enclosure
