Sub box mounting

[V8 Vol]

I installed 2 10's but twice now the mounting has failed. I have the box on the top of the "hill" pressure mounted to the upper deck and a custom lower extension.

It is physically mounted to the car with a small bracket with two screws at The top middle rear of the box. This way of mounting is failing at some point during driving.

The screws are separating from the mdf.

Does anyone have suggestions on a better way??

I've had a Zenclosure box in mine since 2010. I mounted it with two metal L brackets bolted through the car (where the hump is) and bolted into the box. Has lasted through several hard launches at the track without issue.

Only downside is to remove the box you have to remove the subs to get to remove the nuts.

I would either use "L" brackets on the bottom and that at top or I would drill two holes in the top and through the frame of the rear decklid and bolt it through the metal with big washers. You can use silicone to seal the box up.

I know nothing about audio fabrication but coming from a carpenter those screws are way to small for mdf.

Thats kind of what I was thinking (why i included the pic). They ripped out.

I was considering attaching a small piece of wood to the back of the box with longer screws and then using that wood to attach on the bracket......

Use 2" decking screws, problem solved.

^^ this, decking screws, and pre drill the holes with a SMALL bit.

Thanks guys, I will update my screws and hopefully that will take care of it.

You can probably also use t-nuts with bolts, this will require drilling a hole and putting the nut inside the enclosure, but it'll give you much more surface to hang on to...
