bmwking Posted February 25, 2020 Report Share Posted February 25, 2020 no bracing inside the box? Link to comment Share on other sites More sharing options...
bcbrassard Posted February 25, 2020 Report Share Posted February 25, 2020 Needs Bracing in the corners for strength and deflect the sound waves, a round over bit on the port boards will help with sound, Wouldn't hurt to put a 1 1/8" doweling rod from front baffle to port and possible on the other side of the port. Front could have used a double baffle. I would counter sink all screws so you can have a smooth surface all around to finish the outside as nice as possible. The resin for the inside is unless without the proper bracing. Not trying to be a dick or negative just giving solid advice that most have learned on here. I am almost certain your box is flexing and over time will fall apart. I am glad it sound good, i know with the bracing and round over port edges it would sound better.

ehall8702 Posted February 25, 2020 Report Share Posted February 25, 2020 Yeah the corners for sure, if it wasn't such a big box I'd say don't worry about anything else but at 4 cubes that's alot of unsupported board lol.

I just ran outta time, and didnt wanna drive around all week with no bumps, lol i didnt think about the port edges tho, good reminder, thanks again! Not at all, its been 10+ years since i built a box. kinda rushed this one cause was excited, but will hopefully have it finished up this weekend. 15" Neo Elite 135AH Lithium Bank Taramps Bass30k 320a Brand X Purple Metallic Ho Alt 125+ Ft of oversized 1/0 Link to comment Share on other sites More sharing options...
bcbrassard Posted February 26, 2020 Report Share Posted February 26, 2020 So examples: All screw holes counter sunk. Dowel rod position marked on double baffle next to sub cutout. Round over ports. There is a 1 1/8" dowel rod about 3" away from sub cut out. 12" RF T1 D2 on 1k. Doing a rebuild on this car and bumping up to 2k for headroom. Take pics of your bracing and update. Again in my opinion the resin is a waste of time compared to proper bracing. If you glued all joints that should be more than enough, If you think you need a bead of glue or caulking i would go that route. Link to comment Share on other sites More sharing options...
MichiganBumps Posted February 26, 2020 Author Report Share Posted February 26, 2020 Man thats nice lol Next box will be more so like that, i literallyl have no room to do a baffle now on outside, im going to end up having to add wood bracing on inside, or maybe a rod thru side to side and front to back. with angles on inside. Very nice job dude 15" Neo Elite 135AH Lithium Bank Taramps Bass30k 320a Brand X Purple Metallic Ho Alt 125+ Ft of oversized 1/0 Link to comment Share on other sites More sharing options...
bcbrassard Posted February 26, 2020 Report Share Posted February 26, 2020 Thank you sir. You could do a baffle on the inside of the enclosure. You are definitely on the right track with the bracing. With this enclosure i build i had to take the back panel of the trunk trim & the latch off to get it in and out. just a suggestion. Link to comment Share on other sites More sharing options...
