Well my dreams of breaking the 150db mark are fading quick..im just going to grow some balls and wall my maxima with 2 Fully loaded 18's w/ 2 4kw amps or maybe 2 gp3000d pros at .5 ohms..

anyway the thing is i dont know where to place the port

1. subs on top and the port on the bottom?
2. subs on bottom and port on top(my first choice)
3. sub on each side and the port in the middle (least fav because of the length of the port)

post here which one and why...

also the box i came up with should be around 12cuft net after port and woofers all doubled birch and i plan on adding fiberglass resin with 2 2x4 for braces..

u don't have 12 cu.ft. to put 2 18's in I'm assuming unless you plan on starting the wall past the b-pillar

port on drivers side and subs stacked on pass side can get you mid to high 150s with that equipment.

They look pretty to some people. and it doesnt matter too much when you can do this.

Port in the middle and sub on each side will be least loud, subs on pass side and port on driver side will be the loudest.

Port on top and subs on bottom will be almost the same as port on the bottom and subs on top. And you should be able to break 150 with these setups.

Actually the red van has a really nice looking amp rack. but I dont have any pics of it because I am more into destruction. lol

But I know what you mean.

Most importantly brace the baffle to the back wall. If the baffle flexes you will have alot of loss.
You can use 2x4s but I mostly use 1" square tube steel filled with fiberglass resin to eliminate resonance.

I have my jeep walled with 2 18" MTs on a jbl A6000GTi and it is a sub on each side and port in the middle and im doing a 153.1 legal certified at the dash. And windows down on music im doing a 154

Although.... i think i have gotten bit by the spl bug again and i may be doing a rebuild on the wall..


Btw.. Hi ED! lol

are you going for numbers or just insanely loud bass? if its just numbers a 150 can be had with 2000watts or less.Just takes a little time screwing around with the box,,by the way Ed i made the baffle thicker and gained 1.1 Db:)

that sounds good..

loud bass with music for sure!!!

Heres what i have in mind
-entire box double (1.5") the sides and back maybe have another layer added(2.25)
-entire inside resined
-32 hz i designed it for 32 but with the bracing and resin im hoping it wont go beyond 33hz
-140sq in of port area
-some 2x4 bracing


Now for the part i can get over..I know i mention this before but i cant decide on port on top or bottom. The port will be 28" by 5" i think making on the bottom will be easy but port on top seems to be better..(no seats blocking air movement)

Good for 155.5 burps flat within 3db from 36 to 63 bass raced a 52 on 2 MM4000.1 and 4 2150. ugly as hell but had potential to look good.

Sweet, I knew you could get that thing louder.

Threaded rod is easy to use. I just never felt they were clean looking.

The 1" square tube can be easy if you use L brackets.

2x4s are the easiest to use.

You can get all the supplies at Home Depot or Lowes.

They have various sized steel, L brackets, and steel screws to attach them.
You can get a metal cutting blade for a jigsaw or circular saw, and pre-drill all your screw holes.

To reduce vibration, it would be best to fill the tube with fiberglass resin or expanding foam, after you attach the brackets.

i think im going to use threaded rods because of displacement of 2x4's
