So, not only do I have the issue with the sub box not fitting in the corner of my trunk, but I noticed that the sub sounded damaged or torn. Turns out thankfully, that the sub is not damaged but there is a huge air leak from where the sub is screwed into the fiberglass box. I will have to unscrew the sub and see if I can put anything to seal the box cause the air leak is pretty substantial and u can hear it.

Was wondering if anyone had any advice? I've read up on some silicon sealer but some ppl say it doesnt work well. Any advice here for people who build their own fiberglass sub boxes? How do I get the speaker to be airtight when screwed down?

Thanks in advance

Yeah I'd say some real nice quality silicone, none of that garbage at like walmart that comes in a big tube. Either that, or just get a fiberglass repair kit and patch 'er up!
