So recently I got my DC5K running my two DC XL12's and they were sounding great.

A week ago I noticed a harsh rattling noise that I figured was my fiberglass trim piece around the subs or maybe the rear deck.....

Boy was I wrong once I started looking closer.

Well check out the bottom edge of my sub baffle (pardon the dirt, I'm still working on the front of the box):

Yep...the whole bottom edge is cracked apart from the bottom plate of the box.

This is a double baffle of 3/4" MDF which is also cut on an angle so there's >1.5" of contact area which broke loose.... :faintthud:

Here's a video which shows the issue better:

I was hoping it wasn't something serious like a damaged sub or something, but I was quite surprised that it turned out to be this.

My first reaction was to be pissed, but I have to say I'm not mad at all, in fact I'm quite impressed.

It's not like I have a wall either with long sides that could flex. This should have been pretty solid.

Hmmm, maybe I didn't use enough glue, who knows...?

Anyway just wanted to share.

Rusty, thank you, I think ;) for definitely making some bad ass equipment. :D

:good:

What kind of glue did you use?

Good question!

I was meaning on including that, but forgot to add it although it should be buried in a previous page of the build.

Titebond3 and it should have been a liberal amount, but maybe not...

Should be fun trying to re-glue it and get it properly sealed again.

May have to beef it up some more to make sure it doesn't happen again.

Fiberglass! I used a lot of glue, calk and used heavy grade fiberglass inside my whole box. Seems to be holding up very well for now haha.

I like to pour some resin on my corners, let it self level/cure to a 45 deg. angle, then do a a couple layers of glass on top of that. Makes the corners strong as fawk ;)

Glue only or did you nail/staple or screw it as well?

Only glue. I had pocket holes drilled, but wasn't getting the screws to bite and grab like I needed them to so I scrapped that idea and just glued.

Looks like I'll probly be trying to retrofit some screws back into the baffle now.

Plus some other things to strengthen it.

In the future, if I ever have another angled baffle, I'll be designing it with more stability then just a glue joint.

I figured a glued double baffle would be sufficient, but I clearly underestimated what 5000W of DC power can do...

;)

Yep that's a good idea.

I built my box in my trunk though so there's no way I could tilt the box enough to pool resin in a corner.

I may be trying to fiberglass that weak spot in my box. That should help.

My mirrored plate is slightly in the way though.

We'll see what I can come up with.

Ahh thats the issue. Glue by itself is not quite enough. Even brad nails are better that nothing. But you want something to help hold it. Another option when you cant use screws is those little wood dials that you drill for and insert. That at least gives some support. But if it were me I'd add some steel ;)
