Looks good! How did you figure out the port dimensions?
Thanks for all the good info & time you devote to the site.
I'm getting ready to do a little audio upgrade to my Cruze (12 Eco.) So my brother works for Harman and got me a good deal on some stuff:
Amp - JBL GTO-5EZ
Sub - 12" Infinity 1262w
- 50 watts RMS x 4 at 4 ohms + 350 watts RMS x 1 at 4 ohms
- 75 watts RMS x 4 at 2 ohms + 500 watts RMS x 1 at 2 ohms
- 150 watts RMS x 2 bridged at 4 ohms + 500 watts RMS x 1 at 2 ohms
Dual Voice Coil
Sensitivity 93 dB at 2.83 watts
Frequency Response 23 - 400 Hz
RMS Power Range (Watts) 100-300
Peak Power Handling (Watts) 1200
Vas (liters) 80.14
Fs (Hz) 25
Xmax (millimeters) 13
Front - Kappa 63.9i
Back deck - Kappa 692.9i
I think I'm going to keep the stock head unit for now and I'd the smallest sub box possible & still sound ok. I listen to mostly 90's rock/rap and maybe more current stuff like Beck/White Stripes/Flaming Lips I also listen to lot's of audio books & podcasts.
So fell free to give any suggestions or tips, all is appreciated.

Bracing is recommended, but not required at this power level. You could get away with just a few straight pieces of bracing instead of routed bracing like I use on all of the boxes I build. However, a double thick baffle with a flush mount is highly recommended.
Let me know if you have any questions or want to see the frequency response chart.
So 3/4" mdf right? & you have linked to the acoustic pad in this thread before, are there any places locally to get that stuff?
Sure I'd like to see the chart if it's not too much trouble.
Look at this website to see if you can find what they are selling locally at a home depot. Don't just buy any random insulation as it won't work. Acoustic Insulation - Order Online, Ships UPS
Line all of the walls except for the baffle. If those specific products cannot be found, buy this:
Acoustic Foam 2-1/2" x 24" x 18" UL 94 260-515
Here's your frequency response, with the acoustic material on the walls.
