Default Ported boxes for the Z

is the Z pretty easy to get loud in? I cut out the pieces for a back-firing, side-ported enclosure, and will be gluing it together tomorrow. Anyone have suggestions on what the Z likes, such as port and sub orientation? I have built a box for a 10" subwoofer that is 1.3 net tuned around 33hz with about 20 sq in of port area. Starting small right now with a 300-500rms amp, might go to 1200 rms later on.

Thank you!

Loud is subjective , loud to me in a Z33 is 150 DB sealed up on the term-lab @ 40 Hertz ..

But as loud goes you have an advantage in a Hatchback. Sounds like if your goal is 1500 watts tuned at 33 hertz with a single 10" your going more for nice sound that does well on the lows.

yeah I would need a very efficient box to do a 150 with a single 10 on 1500. Where is the port firing? What does it do on the meter if I may ask? I have about 1.8 cu ft gross so its about 1.3 net which is perfect for a 10. I am looking at the FI SSD's, hoping to do a small hairtrick, LOL I know.... who doesnt.. just hoping because the cabin is super small I can pull it off with a single 10. I rearranged the box to sub fire upward towards the hatch and port firing to the rear. I felt that firing to the side was too close to the wall and it wasnt "breathing" properly which made the lows sound non-existent.

You would need more than that to do 150 on the TL. I had 3 setups i was able , ( FI BTL 12" on a RF Power T4000 in 2.75' net cubes @ 40 hertz ) ( DD 9515G 15" on a Sundown SAZ -3500 in 3' net cubes @ 40 hertz ) ( DD 9515G 15" in 3' net @ 40 hz , on a Crunch GP3000D Pro Ground Pounder ) Plus 200 amp alternator , 2 AGM batteries , 6 runs of 0 awg 100% OFC copper . 200 square feet of roadkill, Subs always up , Port always driver side rear corner. .

I don't do that anymore my current set up i never metered , just music now for me . 2.25 ' net @ 30 hertz , 3 x Sundown E8's , off a sundown 2000, the lows kill .

Are you trying to meter high or trying to play lows , you can have 1 or the other in most cases never both .

Not trying to do a 150 on the TL. I'm not going to add extra batteries, or alt. Never metered any of my cars, but just trying to smash the lows, and get lots of air movement on stock electrical. Would you say your E8s get pretty windy? Was just hoping because of a hatch and a small cabin it would be easier to do on stock electical

2 runs of 0 awg for your + & -
Big 3 in 0 awg
stock alt is 140 amps
do that and you can run the 1500 @ 1 ohm just fine
tune low 30 hertz
you will move air and it will get low
hair tricks probably no

Thanks for the advice, Do you think a sealed 15 would move more air? I have modeled an FI X 10" and SSD 10" in WinISD in the same 1.3 net enclosure, and WinISD showed that the X would outperform the SSD in every single frequency. Should I go with the X based on WinISD?
