DIY Subwoofer Box for Suzuki Swift

Hello, what is going on world? Just finished a cool project and now I'm back uploading videos and here is my first one for the year 2022! Pardon me for being away for so very long, it is because I am now very busy doing installs and taking care of customers' cars and boats locally.

Without any further ado, let's get this thing bumping!

00:00 - Unboxing the CT Sounds Tropo 10D2

- Main component used is a very cool CT Sounds Tropo 10 inch 600w RMS dual 2 Ohm subwoofer. Bought this locally from a grey-market supplier at a very reasonable price. And I think it's the perfect size for the Suzuki Swift 2021.

00:35 - Measuring the angle of the Suzuki Swift's rear seat inclination.

- Swift's boot space has only a very limited space so it is best to build a trapezoidal box space-saving wise.

00:55 - TinkerCad 3D schematics is available on this link https://www.tinkercad.com/things/0hBK...
01:10 - BassBox 6 Pro calculations.

- CT Sounds Tropo 10D2 has a factory specs of 41.8Hz of open air resonance or Fs. I calculated the box to have an effective tuning of 40Hz, just very close to its factory Fs theile-small parameter for a nice roll off on its peaks on both sides. The output graph shows that I tried to feed a maximum power of 1200w to push the vent velocity nearing max inner turbulence.

01:25 - Box building starts here.

- MDF is always the go-to readily available and cheap box building material. Best for subwoofer boxes for it is a dense board and does not produce springy resonance.

02:00 - Cut a semi-circle notch on the front baffle for added accent.
02:15 - Use the measured rear seat inclination angle for the rear panel wedge.
02:40 - Cordless drill is super handy in flaring PVC pipes into aero ports!
03:10 - Use chamfer bit on the edges of middle bracing to promote smooth air flow.
04:50 - Rubber cement is very good in adhering carpet into the enclosure.
05:00 - Sanded the PVC port using 220 grit sandpaper before spray painting.

- The key in spray painting is to apply multiple thin coats than a heavy single coat. Patience is really a virtue if you don't want paint to puddle up and drip like a mother nutter.

- I always use T-nuts and Allen head machine bolts in fastening the woofer into the box. Because I like all my works have the highest quality.

06:00 - No nail all purpose adhesive can be very good in securing the PVC aero port. Rubber cement works well too.
06:25 - I stuffed about 100 grams of polyfiber fabric material inside the box for added resonance dampening.
06:50 - Finally, secure the woofer using Allen-head M4 Carbon steel machine bolts.
07:00 - Everyone, meet our new family addition, Smol the cute French Bulldog puppy!
07:45 - Dayton Audio DATS v3 measures system impedance.

- Final and verified measured box system impedance and tuning is 40.37Hz on the DATS graph. Just perfect box tuning for the CT Sounds Tropo 10D2 which is factory spec'd at 41Hz open air resonance. This newly built subwoofer should produce smooth, low and accurate bass frequencies no matter what the music genre.

08:10 - Subwoofer perfectly fits inside the boot space of Suzuki Swift!

And that wraps up the project. I hope you like this new episode of subwoofer box building and I hope you'll stick around for more future cool and awesome car audio builds! Stay safe and have a nice evening, everyone!
