EA B D sub box

Hi all,

I've got 2 Earthquake BR12's that I want to put into my EB Fairmont in the next week or so and I was looking and measuring the opening behind the rear seats today, I need about 1 cu ft per sub and I have nowhere near enough room to fit them. I considered putting them on a board behind the back seats and running them free air but I suspect this setup will sound shite. I need the majority of the boot space to fit my toolbox so I can't have anything massive. I also definately want the box ported. My questions are;

1. What setup have you guys done with 2 12's? Pics please?

2. Did u face them to the front or back? What about the port/s?

Please help! I want to do it once and do it properly

For pics

this is an 80-85 L box 2 100mm ports coming up through the stock rear speaker holes in the parcel shelf, i have relocated my rear stage more towards the outside of the car, thin carpet over the top so no noise is blocked, or if i wanted to make 1 single box, do a port thru the factory subby hole, which i had when i have sealed box, have since then moved onto ported and now bandpass but this can be quite difficult and will take a lot of ur space but u get good results, (120L box for a rough idea) up to u which way you want to go... good luck

Re: EA B D sub box

Unless you have LPG the 12' subs should be a breeze to fit.
Angle the front to follow the back seat. Mease the width and be sure you take intconsideration the rounded edges in the boot. Hight is deceiving as the hight you measre will be to high to fit in. I can measure mne if need be. The depth is dependant on the CC you need.

Re: EA B D sub box

Mate those old BR12's or BR1270's need huge boxes, if you try to put them in any smaller than 100ltr ported box(thats each) the ports are heaps long and very inpractical(1m +!)and this will make it sound very boomy. These dinosaurs really like big ported boxes. The best thing you could do with these is use the 2 of them and using youre whole boot as the box(you must seal the boot completely from the cabin...)free air like you said dont worry they wont sound shite as its what they were ment for! If you wanted small boxes you would have brought the EQ series subs.
Use them as a home theatre sub where you can afford a huge box.

Takin it to 7 turnin it to 11
