[Drummer65 10+ year member]

So at the age of 19, my goal in this moment of life to hit a 150dB from the trunk haha.

Decided to go with 2 DD 9515g's strapped to two Sundown SAZ-3500d. All the equipment will be in the trunk.

Empty trunk

50sq feet of AudioTechnix 60mil

2 Batcap 4000's, 1 Batcap 3000's, 1 Deka 8a31

Gross Volume 8 cubic feet, Net volume 6 cubic feet. Designed the box myself. Biggest box I could possibly fit in my trunk. Port will be facing inside the cabin.

Looks great, why did you choose to not seal off the trunk and fire into the cabin? Thats the best way to get loud with a trunk. You will gain output if you can get a 45 in the corner of the port to direct the air more efficiently.

The port will be facing into the cabin, the box is only 13.5" tall so the only option was to have the subs facing up. The port wall that is angled is whats going against the folding seats.

not sure if its smaller then my civic's trunk but if its anywhere close to it i'm sure you could fit 8 cubes. I would have done 2 8" external aero port into the cabin however I wanted to be able to fold the seats up. After port and sub displacement im right around 6 cubic feet.

Its what i could afford haha. Depending on my voltage drop I may have to invest in some D3100's

Like 5.8 cu ft is what I can fit from what Ive tried. My trunk opening is what ruins everything. Im actually aiming for 150 as well. In my 96 accord, I have two 12" aq hdc4's off a sundown saz-3500. Im currently doing a 149.2 off music. If I remember correctly, my box is like 5.79 and around 4.1 net with four 4" pvc ports tuned to 37 hz. Im gonna rebuild my enclosure and have a 10" flared out external port facing inside the cabin and Im going to add another saz-3500.
