Hey guys, so here is my first build, nothing fancy as I am pretty new. I struggled designing a box that would fit into my trunk, but after three or four designs I decided to go with a angled enclosure, max i could get was 6 cf tuned at 34hz....but they work perfect.....couldn't find any arrows yet but I have not had any pipe whistle......

the set up is, 2 15" DC level 4's powered by the MB quart 2000.1 wired at .5 :)


PIcs fixed!

Deeper_shades
02-05-2010, 01:31 AM
Yup they hit Super low in 3cf. They have such a warm clean sound


Btw I talked to mr. rusty him self and he said the 15" sound great in as small as 2.5 each.


Keep me posted is love to see you your cooking up, DC is king

That is very interesting, I ran a DC Level 4 18" in a 5.5ft3 net box tuned to 32hz and sounded great in my trunk, clean and low. Thinking about going back that way. :D

How is that MB Quart 2000.1 handling .5ohm? Pushing the subs well? I have the 4125, (even though its out the car at the moment) and I love it. Compares to my Sundown 125.2.

02-06-2010, 02:25 PM
ya, its good, putting out quit a bit of power but I wired them back to 2 ohm until I get my batts from sonic, the yellotop just wouldnt handle .5 ohms....next step is new alt, but im going to wait till I get my tax return for that

Deeper_shades
02-06-2010, 05:16 PM
I made the biggest box possible for my trunk, dc level 4 15" require 3 cf per sub, I have made a 6 cf shared box tuned at 34 hz. I didnt have the space to put in a slot, so I used areo's

my subs sound great and hits low and clean in this box, the port size is fine

You could have built inside the trunk and gotten more room. A slot port would have fot on the side easily, and 3 cubes is probably minimum size for them.

Actaully 3 cubes is recomended for them, stop picking dudes **** apart. IF it was your car, you couldve done it differently but its not.

Ok., then going off your signature. Your car is a piece of ****, the Autotek is a pretty low quality amp, better speakers can be had for the money than those MB Quarts, The AQ 2200 isnt enough power for those subs.

Yes, the shadow was a piece of **** and it broke down, i dont even have a car to drive right now. The autotek amp was $25 brand new and it does its job just fine, and the mb speakers were $10 brand new so i dont think i can find better for the money. The 2200 was enough power for the sub i was using it on. My single 12" boxes use that much port area, its not enough for those subs with that power.

Lets get back on topic yes?
I think everyone is entitled to their own
opinion so lets just let all this go and
review his set up. Whether you like his
set up or not he just wants to hear what
the average bass head has to say.
Its all good no one has the perfect system
so lets not worry about constructive critisizm.
I would want to know what people really think
about my system if I were to post it on the forums.

first off, this is my first build, and I dont want to completely write off my trunk as unusable....second, If you read ANY of my posts you would have seen that I talked to RUSTY from dc and he said the level 4 sound great in as little as 2.5 cf each, I have them in a 6 cf SHARED box, its more than enough just like the three round ports I chose to use give more than enough air flow. Like I said in two post, the subs sound great, and hit clean and low......so what are you trying to prove here?

if your know so much, you design a box with these measurements, ill build the box and tell you if it makes any difference,

length 36
depth 29
height 15

tuned at 34hz please


he shouldnt post a build log if he doesnt want his "**** picked apart".

again, I really could care less if you think slotted ports are so much more effective than round ports, your entitled to you opinion, and Im glad you dont like my build.....I think is pretty ****ing awesome considering the space i had to work with and my lack of experience, have fun picking away at the new people on this forum, probably why people dont make it past 50 posts......

Id really like to see you design another box :) I will seriously build it if you can think of something cool

ran pretty good, seemed to stay pretty cool, But I only ran it for a few days, My electrical cant take it, put it back to 2ohms for the time being, waiting for my new batt in the mail, I live in canada and we are limited to some of the cool stuff you guys have in the US.

the difference was loud at 1/4 gain at .5 and loud at 3/4 gain at 2ohm but Im still breaking in the dc's!!! so i haven't gone stupid yet, but as soon as I get my second batt and the subs have primed, I will fill ya in...

man you really have a problem reading my posts, i said twice if you can design a box with more air space I WILL build it.....

I made a build log because Im proud of my accomplishment, you where the one saying "he shouldn't post here if he doesn't want people to pick him apart" I was simply clearing up that I never made such claims that your opinion bothered me, I dont know why your assuming its bothering me, Im telling you with my skills I could not figure out how to fit a slot in and if you can get me a bigger slot port with 6cf than id love to build it :) im taking your advice into consideration man.....


so lets see what you can come up with....


a thing to keep in mind though...

on the angle of the face, I will have to be able to put the subs in with out the spider or the motor hitting the bottom, what I did was I added a 1.5 inch strip to the bottom length and i connected the face to that instead of connecting it the the bottom length. than I cut part of the bottom length on a angle so that the box just barly fits in my car....

Man you just showed your ignorance. Its the same thnig, these just are not flared. and flares are not necessary, they just reduce noise if you have a noise problem. What do you think PSP aeros are, they are PVC with a thinner wall. Why do you think the PSP-Inc calculator gives lengths for both flared and unflared.

Now since you dont realize this. 3 4" aeros are better than 1 12" aero so do you think a 12" aero isnt big enough too, he might have too much port area.

a 12" aero would be about the same as 9 4" aeros, so i dont know where you are getting your numbers.

I think you did a pretty good job for your first build. If you are happy with the results then that's great.


I thought I'd add a little useful info for everyone to clear some things up.
People are really confused about aero's and pvc ports...aero indicates the fact that it is flared to reduce turbulence and improve airflow (on both ends). PVC can be made into a homemade aero by creating you own flares but very few people do this. Here's an example I made:

http://c1.ac-images.myspacecdn.com/images02/85/l_35efcb7088274b88bc1d8047f4d5a780.jpg

I have done testing that proves that flared ports (round and slot) outperform unflared versions. The more power you apply or cone surface you add makes the problem worse. A safe rule of thumb for calculating flare "effective length" is half the physical length; so a flare that's 2" long can be calculated as 1" of port length. It does depend on the flare radius but it's not enough to matter in most cases.

3" port =7 sq"
4" port=12.5 sq"
6"port= 28 sq"

The formula for this is just: area of a circle= 3.14(R x R)

Clearly (2) 3" ports DOES NOT equal (1) 6" port and a round port is not always superior to a slot and vice versa. Its application dependent and you need to balance box size to port area with regard to power and sub capability.

OP-sorry for a small thread jack I just thought people could use the info!

3.14*4*3 = 37.68
3.14*36 = 113.04

Swing and a miss on your area calculation, but most of your posts are spot on :)
Or were you referring to the OP's build specifically?

But anywho, if ~37.68sqin is working for OP's 6 cube enclosure and he's happy with it, then hooah!
Glad your first build went well!
