I had been out of the audio game for a while, but the itch never went away. The build was going to have to stay within a small budget and it had to sound awesome. I have built many different systems over the years, but this was the first Tline type enclosure I have ever built. The port folds back and forth through the box and goes down one side and back up the other. The Line is 11.5" X 5.5" and the box takes up about 6 cubic feet. The port exits through the top under the factory sub hole and the sub is mounted inverted on the front of the box. The trunk is walled off. I made a couple of viewing holes in the back just because and the inside of the box as well as the amp racks are lit by purple LED's that are wired from the trunk light. The sub is currently a Sundown EV3 12 D2 running at 1 ohm on a Pioneer GM-D8601.

Very interesting for sure, so sub forward, but port exits up into the factory subwoofer location? Too cool!
 
Thank you guys. I have all of the pics for the completed trunk, amp racks and such. The pics just weren't cooperating earlier. I'll try again in a few when I get a sec.

Traditionally tlines do have stuffing, this one does not. It does nave 45's in the corners and was painted white and many other colors. The line is also about 18 inches short, which put the tuned freq at 36. It will play well up to about 70 and can play down to about 28 or so. I use the crossover points on the deck to act as a SS filter since the amp doesn't have one.

This box started as an experiment to see what I could do for next to nothing. The wood was a recycled desk unit made from 3/4 MDF that I found on Craigslist for free. The window side is MDF with a layer of plywood that was free. The 1/2 inch plexi was from a recycled printer stand that was free. The lighting cost $5 on ebay and I did the whole trunk with it. The later parts of the build ended up costing and the Sundown sub in it now was bought new.
 
Here are the build pics of the amp racks. There is one on each side of the car. The passenger side has the Pioneer GM-D8601 and the driver side has the RF r250.4. Pics are for the sub amp, but both are built the same.

Next was wallling off the trunk. The port is no longer on the front of the box and the PPI sub is gone with a Sundown in it's place. There was a lot of experimenting on getting this to work like I wanted.

The back of that box is super ugly sitting there, so a vanity panel was next. I made the frame and stretched fleece, then fiberglassed it. It has magnets that hold to L brackets on the side of the box.

And finally the moment it took about 2-3 months to arrive at..

The panel can easily be removed and the spare tire, battery and fuse panel that are in the trunk floor are fully accessible. I have a few more pics that will come once the door pods are done, however I have yet to start on them. I hope you all enjoy.
 
For my 2011 Dodge Challenger, I embarked on a budget-conscious yet awesome-sounding audio build after a hiatus from the audio scene. Despite having constructed various systems in the past, this project marked my first attempt at a transmission line (Tline) enclosure.


The enclosure's design features a port that snakes through the box, moving down one side and up the other, with the port's dimensions at 11.5" x 5.5". Overall, the box occupies roughly 6 cubic feet. The port exits through the top, utilizing the factory sub hole, while the subwoofer itself is mounted inverted on the front of the box, with the trunk completely walled off for optimal sound isolation.


I added a couple of viewing holes in the back for aesthetics, allowing a peek inside. To enhance the visual appeal, the interior of the box and the amplifier racks are illuminated with purple LEDs, wired directly from the trunk light. The subwoofer used in this setup is a Sundown EV3 12 D2, running at 1 ohm and powered by a Pioneer GM-D8601 amplifier.


The result is a visually striking and sonically impressive audio system that balances budget constraints with high-quality sound performance.
