2016+Camaro JL Audio SB-GM-CAM6G隱形箱支架

I purchased a JL Audio Stealthbox second hand. The initial italler elected not to use the included bracket and just drilled holes in the subbox and the car. (I know, right?) I repaired the box, but did not want to wait for JL Audio to ship a replacement bracket, so their excellent service rep gave me exact measurements from their dimeional drawings and I created this based on those numbe. After patching up the extra hole in the fiber glass and testing this out it fits perfectly.
I used this mockup in PLA to test the provided measurements but more importantly as a template to make a new bracket out of steel. I suppose it would be possible for you to print this out of ABS and use that, but I recommend using this as a template like I did. Anything weaker than ABS will probably not hold up in the case of an accident. The sub & box weigh about 45lbs, so it's better not to take chances.
