Hey it's me, the guy who made the other post about spacer material.
Well, the board from an old shelf didn't work at all. they cracked before I got done cutting them.
Then I found some particle board in my shed that was left from the previouse owner.
Well, i made the spacers round so they just fit the speakers....well these split when I screwed them into the box (I even drilled holes for the screws)
Now I made new spacers that are square to fit the box so there's more space between the screws and the end of the board.
Does anyone know if particle board is good enough, or is it too soft?
Do you think it'll split on me again?

particle board is soft, and does have the tendancy to split or crumble. If you drill the holes almost the same size as the screws in the particle board, but not in the box, I believe you should be ok. THe screws don't need to thread through the spacers, only into the box.

Hey, good point!
last time I made the holes quite a bit smaller than the screws.
You probably saved me a lot of time and another big headache.
Thanks again

Most partical board that is stored outside any length of time will absorb moisture, swell and then flake apart. The moisture breaks down the bonding agents that hold the wood particles together. MDF is better.
Regular wood planks have grain problems that eventually lead to warpage. They will split if you apply pressure to them.
MDF is a good choice as easy to cut, remains dimensionally stable and strong. It too, can attract moisture, but at a slower rate than regular particle board. The MDF is more dense and better glues to keep it stable. A few coats of epoxy based or urethane paint will preserve the wood well.
As noted by Kit, predrill all holes for mounting the panels to the box face, to same size as screws used. On the sub screw holes, go undersized pre-drilled pilots. (about 50% of mounting screw dia. Better yet, use tee nuts and bolts. (1/4" x 20 is fine, 1.5" long should do)

I know you mentionend not having many tools, and not wanting to buy a sheet of MDF. Go to home depot, they sell MDF as shelving material-precut to sizes like 12 x 36, 16x48 and others. This will save you a little time and money and splitting.

Yep, and they will cut them to sizes for you too... ~$0.50/cut.

MDF sheets seem hard to find here. I called some different building supplies looking for MDF and the only thing they could come up with is three quarter inch thick in a 4x8 sheet for $29. I called a cabinet maker and he said he could order a sheet of quarter inch, taking about a week to get it in for me $20. cplkittle, I never thought of asking them for shelving material. Good idea!!

Try this... go to the cabinate maker shop and look in his dumpster. You may find all you need right there for free.

I recently had the same problem installing two tens in a f-150 under the seat. Go to home depot in their wood deparment you'll find already precut mdf wheels. They cost about $2.50 a piece if I can remember. The only thickness I found though was 3/4". The diameter of the wheels is between 9 1/2 & 14". I then just took them to a cabinet maker. Who charged me $20 to cut both of them to size. He even predrilled the speaker mounting holes for me. The only problem I had afterwards was air leakage. I didn't get a chance to seal it up yet, probably do it this weekend. Maybe someone here can suggest something to seal between the rings and the box.

Silicone, felt, neoprene or cork gaskets will help.
Silicone is semi-permenant... if you remove the sub later, may have to cut the silicone bead out with a razor knife. Potential cone damage if not very careful in the process.
The other materials are soft, pliable and easy to cut to a specific size/dimensions. They can stick to the box or the woofer lip if removed, but easily removed with a scraper.

what size are the speakers? I would go to the cabinet maker, or a local shop and ask if they have scrappes, maybe offer money...
