New subs dont fit enclosure

[Voodoochi1d]

So... i feel like a complete *******... I made sure the RF 10" Subs fit by the depth dimensions, but I didnt even think about the top mount frame dimensions.

The new subs dont fin into the MTX Thunderform enclosure.
The frame is about 1/2 inch larger than the frame of the old MTX Subs.


here the sub sits in the enclosure, but will not fit because the frame is larger than the enclosure will allow.



Here is the MTX on top of the RF sub.


Im not sure if I want to sell these subs locally, (1 still never opened, and 1 was opened, but put right back into packaging), or if I want to replace the MTX enclosure with something else.

I dont like the foxbox and probox enclosures, you have to raise the back seat with both of these enclosures, and still get less internal volume than with the MTX enclosure and I dont have the rear seat raised at all.

Anyone know how hard it would be to modify the enclosure, and form a new top and new Sub mounting hole?

so is it in just that one corner where the sub is hitting? Is it all ABS plastic or what on that MTX box?

I'd just trim the outer flange of the sub a little at a time until it fit.

so i cant trim the sub, cause then there nothing left on the sub to screw down.
on the MTX box, yes entire enclosure is that abs plastic.
Was thinking that maybe i could build new enclosure using the box as a mold to lay fiberglass on bottom of mtx box. then pull the shell, and lay more layers on the inside of the shell so its only slightly larger than the mtx. should still fit, but could sand after dry to compensate, correct?
