i didnt see them on the website:confused:

[scottd1975]

No there not there anymore... i dont want to spend the money on a MTX i heard crappy things... finding a nice looking sub enclosure for a 12"sub is hard if your picky

[huitzi]

i didnt see them on the website:confused:

yea youre right, their site looks different maybe they dont make em anymore

[TOYr32]

[TOYr32]

BTW . . . what do you have? Subs, Amp?

[scottd1975]

i have one 12" sub and a amp

[TOYr32]

where do you want the sub?

[scottd1975]

well i would like it to either sit where the spare tire would go or on the right hand side of the jetta trunk where that net is or on the left hand side where the cd changer would go..

[DTolo]

Damn if my buddy hadn't moved and had his tools, I'd be down to build a box. Haven't done one on my own, but I am pretty sure i could get it done, and nicely!

[scottd1975]

yea i def want a custom box ...

[TOYr32]

Scott, make sure the person who builds it doesn't just make it look good. Make sure it has the proper air space a spec cause all your hopes and dreams could turn to shit when you hear it all farting in your wheel well! :D

[TOYr32]

Maybe ask this guy where he got his work done!! j/k

[scottd1975]

haha i saw that... hey do you know anyone that builds boxes..

[DTolo]

If you can't find anybody... I would recommend checking out a couple shops and just talking to the installers. You never know if they are looking for some side jobs.

ToyR32 makes a good point. There is more to the looks. Structure, specs, and tuning if ported are all things to be considered. Yeah, I have seen/ heard the farting before, lol...

[TOYr32]

Side jobs are key . . . Scott send me a PM and I'll give your info to my old Install Manager from Tweeter . . . he may be looking for some cash since Tweeter doesn't exist anymore!

a good rule of thumb is 1square foot of air space for every 12" .
also if u go custom make sure they use good wood and not shitty balsa wood and taht they use glue and screws to put it 2gether
also do you want it sealed or ported? (portted sounds waay better but it also moves alot more air out which creates the bass and makes sstuff rattle)

Ted, everything you said is all relative. And ported is great, but sealed is most precise.

I's all about matching the system too. Certain subs take more air space than others.

*cough*W7*cough*

[JETTAone420]

ported gives you more of a drawed out bass line
sealed is more of a crisper THUD but with sealed you need the proper space to keep the air in motion without rattling since all taht pressure is gonna wanna move.

W7= makes baby jesus wanna be a gangster!

[jwill'sMK4]

1. ported/vented boxes are louder because the tune of the port/vent allows the sub to dip down into a lower range that it would otherwise not be able to hit in a sealed box

2. a sealed box is more precise b'cuz it doesnt let any air out which keeps u from having bass that too boomy


with ported/ vented boxes it requires more calculation in order to hit the desired tone the also dont have to be huge on the insdie becuz of the free flowing air so if u wanna go with something easy to make go sealed make it fairly big like 2 cubic feet or bigger if u want and use 3/4" mdf wood

also hes using the pioneer premier i sold him so it would kill a W7

anyway if u go custom make sure the make it failry big becuz with custom or stealth boxes sometimes the boxes are big enuff if confined to one space like a spare tire well or corner of the trunk if u get it ported/vented have them tune the box to between 30-40 hz

[TOYr32]

The problem with tuned is you're limited to the range that sub will perform.

Sealed boxes are just that . . . sealed, it allows the sub to move back to the neutral position faster then a ported and badpass box. This in turn created tighter faster hits, so cleaner bass. If you listen to rock at any time, you would want a sealed box. a ported box would sound like but during rock, but a sealed box can sound good with any type of music.

Another thing to consider is that its gonna be in your trunk, so your bass will be deep since it will be in a confined area. You don't have to worry about making some crazy ported box that hits the brown note.

And a Pioneer premeir would not kill a W7 . . . at least not one in a proper to spec box. There's a reason it requires a min of 1inch MDF, cause it will crack boxes that are thinner . . . more coil movement that your pioneer, there is no way that sub would be able to hit half the tones a W7 could!

[DTolo]

In the words of Ted, W7 FTMFW!!!!

Really though, you got a lot of info here Scott. I mean, there are a few things that you have to make sure of, and even more as you get more specific with your needs/wants.

So what really are you looking for? Just all wood and a sub-floor with carpeting, or some fiberglassing? Did you want the amp mounted seperate or incorporated in the box/sub-floor?

[scottd1975]

ok i would like one of two things... i would like the sub to sit on the right hand side of my trunk using the space available where my little cargo net sits.. or i would like a enclosure that is in my spare tire. the amp doesnt need to be hidden but that would be a plus. wood with carpeting would be just fine. no fiberglassing that will get to expensive. i will do some searching and post pics of things i like.

[scottd1975]

something simple like this..

i dont see y not given optimum conditions the premier can still handle 250 rms more then the w7 and it can hit frequencies as low as 18hz

[jwill'sMK4]

scott if i was u i'd make the box in the spare tire well and raise the floor of the trunk 3-6" best of all u could do something like this urself without have to use fiberglass

and a sidenote fiberglassig isnt that hard jus time consuming i've done it b4 with absolutely no previous knowledge so if ur really trying to save money i suggest u do it urself bcuz unless u have a buddy do it for cheap ur looking at at least $50-$100+ to have a custom box made

[scottd1975]

yea i was thinking that . but i dont have a saw to cut the shape of my trunk carpet for the wood.

[DTolo]

JL audio is simply higher quality and produce better sound at the same ratings than most others. I don't know enough about the Premier subs lately to argue much either way.

Scott, if you don't have the saw to cut a sub-floor, then how would you have a saw to cut the pieces for the side installs?

What about the woodshop on base? They have everything. Plus, MDF is a bit tougher to cut than plywood, so a higher quality saw would be useful.

Measure out what kind of pieces you'll need for the style install, then plot them on paper to see how many slabs of MDF you'll need.

[TOYr32]

Fiberglass can actually be cheaper for materials, but very time consuming, messy, and dangerous.

I'm not sure what that pic looks like on the other side, but a beauty board is easy to cut with a jigsaw and wrap with carpet. I'm not familiar with how deep your wheel well protion of the trunk is. But is you could make a box for the sub that mounted to the floor of that corner, all you need is a piece of cardboard to trace out that board. Rent a jogsaw from home depot for $20 and cut it out yourself. It sounds easy, and it actually is if you're confident with tools. Plus, you really don't run the risk of damaging your car like you would if you tried fiberglass and resin.

[jwill'sMK4]

rotozip with circle cutter attachent and some sawhorses is all u need maybe even a circular saw

if u go with fiberglass u can fiberglass the bottom of the spare tire well and lay a sheet of mdf for the top of the box then fiberglass them together u dont necessarily have cut a piece of wood that will be the same shape of the carpet u can make a nice rectangle/square piece and then square off the sides of the trunk

[scottd1975]

well hell does anyone want to make some extra money? if you guys have the tools maybe?

[jwill'sMK4]

also to minimize the risk damageing ur car with fiberglass and resin use tape and aliminum foil to block off the area being worked in the resin cant seep thru the foil and once u lay one or to layers of fiberglass and let it dry u can pull the mold out of ur car and work on the rest of the box outside of the car but dont forget to use rubber gloves and a respirator

one last thing the mounting depth for that sub is about 7.5" so rite of the bat ur gonna need a good amount of space i dont think the recess of the trunk goes in that deep so u will prolly have to pull the box 3-6" away from the trunk wall

[TOYr32]

I would but I live in San Jose, sorry!

[DTolo]

my time is crunched and don't have the tools myself. Still strugglin to get time to work on the golf and get to the range.

Good info, read up:

i vowed to never work with fiberglass again plus its tedious process

[audiracer2002]

Like Lon said, call StreetNoyz.

Ignore the carpet mis-match (the photo makes it look worse than it was, but I chose to not wait for them to actualy get the actual Audi stuff), but they did what you are looking for in my Audi.

Tucked the amp up under the rear deck as well.

[jwill'sMK4]

how much did that cost?

[audiracer2002]

Hard to say exactly. When I did the system, I spent a lot of money on things. That amp is a 6-chanel Zapco beast. It ran the entire system. Unbelievable amp though. I had Focal separates in all 4 doors and then the Image Dynamics sub. I don't know exactly what the labor for just the enclosure was. It sounded amazing though. You could crank it until you couldn't take it anymore with absolutely zero distortion thanks to the amp. Well worth it.

[IfYouSeeKay]

That looks awesome! Holy shit.
