2 12 DC level 3m2, DB Drive A7 2500, I have about 7 cubes available total. Soon will be another A7 2500 and 2 12in DC XLm2s

What other ways, I've tried so many things but a 4th that's all I can think of now. 2 12s is the most I can fit in my trunk and I can only do 142.8 on music, I want to be louder, possibly move some hair and and have a wider range while doing all this.

OK wider range then I have now lol, my current lpf has to be set at 45 an ssf is at 33 lol. I would like to play between high 20s to mid 50s. I don't need to play as low as some people with 4ths, I don't listen to chopped and screwed, but occasionally my music drops below 30.

OK, thank you. So basically now I'm lost lol. Right now I have 2 12in DC level 3m2s on a DB Drive A7 2500 in a 4 cube box tuned to 34hz with 15sq in of port per cube. The rear seat of my 2000 Audi A8 is as solid and sealed up as fort Knox. I cut out a hole roughly 18x30 in my rear deck and hat shelf the glassed it to make it clean again to release to pressure from the trunk. My theory is if I build a 4th order and seal it to the rear and blow through what was once a rear deck it'll yield higher numbers while having a wider range, move a lot more air and no loss of out put into the trunk. Am I correct on my thinking or am I off?

So what's the 4th order bandpass that I hear everyone talk about on like ****? The ones that play loud low and move a lot of air. Its a sealed rear chamber and ported front chamber. That's a 4th order right?

There's a difference? Sorry I only know it by a 4th order bandpass. The enclosure that's a sealed box on one side and a ported on the other.

I'm going to be starting a 4th order blow through my rear deck soon and had a few questions. One being when I port through my rear deck would it be best to fallow to window angle to port straight up into it?

Manly just need to learn about 4th orders if anyone can help

Thank you. Here to ask lots of questions and learn lol

Just saying hi lol
