Sold the car and built a new box. Made out of 3/4" MDF, glued, pre-drilled holes, screwed and sealed. Fits a 12" sub. This is no jerk off ebay box. $80 Located in Niskayuna PM ![http://i185.photobucket.com/albums/x153/crazyz250/DSC00414.jpg](http://i185.photobucket.com/albums/x153/crazyz250/DSC00414.jpg) ![http://i185.photobucket.com/albums/x153/crazyz250/DSC00415.jpg](http://i185.photobucket.com/albums/x153/crazyz250/DSC00415.jpg) ![http://i185.photobucket.com/albums/x153/crazyz250/DSC00417.jpg](http://i185.photobucket.com/albums/x153/crazyz250/DSC00417.jpg) ![http://i185.photobucket.com/albums/x153/crazyz250/DSC00420.jpg](http://i185.photobucket.com/albums/x153/crazyz250/DSC00420.jpg) ![http://i185.photobucket.com/albums/x153/crazyz250/DSC00422.jpg](http://i185.photobucket.com/albums/x153/crazyz250/DSC00422.jpg) ---

Port length and dimensions would help too. GLWS. Car Stereo died 10 years ago. ---

Looks to be about 1.6cu/ft net and it looks to be tuned to ~40hz. What kind of sub did you have in it, that’s pretty small for a 12" subwoofer. My calculations could be off a bit as I’m using a picture as port length reference. LOL ---

Legit subwoofer is legit! 2.5cu/ft tuned to 38hz would be a real banger with it, lol. ---
