Are double baffles worth it?
do you lose the benefits of a double baffle with flush mount?

I think this might be the box I will build... (sub firing up)

or possibly this...

the problem Im running into is that Im afraid that if I mount it on top of the second baffle is that the surround will hit the cover over the rear hatch space. I would just take the cover off, but I may be going to college in atlanta next year and I dont want people to see my stuff. If the double baffle doesnt make too much of a difference or if flush mounting it diminishes the advantages of the double baffle, I was just going to do one.

if your box flex's at all you are losing sound waves in turn you lose sound coming out of the box.the stronger the better

I'd double baffle if ur gonna go with either designs.. If not then at least 2x4 or all thread.. Also you can still flush mount on a double baffle you'll just have 3 pieces of wood there

Also if ur worried about the sub hitting the top of your trunk then just make the box .75" shorter and it will be the same height if you were to use a single baffle

cant go any lower. 26"x30" are my max dimensions for the base of the enclosure. If I decrease the height I have to decrease the volume and raise the tuning, and its already going to be tuned a little high anyways. I dont really want to mess with that

but will it be noticeably different. If Im only going to lose a tenth or two, then I dont really want to bother with a second baffle

You could if your all out of opions build a double setup but make the bottom baffle .75" shorter all the way around so that it will be inside the box and still be the same height but will just lower internal volume a tad. I'd imagine it would work tho.

double baffles are more for holding the weight of heavy subs than stiffening the box.....bracing is better than double baffles for stiffening the box

Countersinking my subs I ended up with a 1.25 face. I broke the single baffle screws,glues,and all.

not on a top-firing box!!!!

If you want more bite for your choice of fasteners, put an internal MDF ring inside the top piece

i would had gone double baffle but i didnt have the wood. as for the subs ripping out of a single baffle. when i am careful its fine, otherwise just use t-nuts. threaded rod is also an option.

Double baffle will do alwmost nothing for you

Bracing it was keep that box stiff if you ask me ( and Ive only ever used big boxes )

A 2X2 8' can be bought for 2 freakin bucks, and just make a brace up and down on your sub baffle, and left and right to the sides, BUT connect the 2 braces with a few screws for even more strength

Ive built 15+ cube boxes out of 1/2" MDF single baffle with just some 2X4 braces and on 3000+ rms and 4 15's, held just fine with NO flex

Forgot, if you can afford it, threaded rod is best, but it aint cheap. The wood braces work very well, but they arent "solid"

Ive only used rod once, but I didnt notice any difference, car owner was happy is all that matters

I just put my SR10's into a 1/4" baffle sort of flush mounted with 1/2" supports. It's solid as a rock, I can't imagine anything flexing it.
