Re: [DML] New Speaker Install...Save original car

"You choice of plywood was not the best. There are reasons why speaker
enclosures are generally made out of that cheap nasty looking
sawdust/particle board. The great looks of the outer plies on plywood are
not an indication of what is sandwiched inside. Even though particle board
is cheap, it has no voids or loose edges to rattle internally."

- The optimum speaker enclosure material to use is MDF (Medium Density
Fiberboard, other grades are available like LDF and HDF..the only difference is
price, density and hence weight). Overall it has a greater density than
particle board, which most cheap enclosures are made out of, it is more
resiliant to temperature change and moisture and acoustically, it is a more
stiff material.

You can find it at Lowe's, Home Depot or most good wood supply houses. For
mounting speakers smaller than 8", 1/2" thick MDF is suitable, if you're going
larger, 3/4" + is recommended.

When I build an enclosure or a speaker baffle, I also like to flush mount the
speaker in the face, this gives a nice, clean, uniform look and if you use
color coordinated grilled, the speakers are almost undetectable.

For more information on car audio, check out www.carsound.com and

As for engine resonance, you could coat panels with either spray deadener, like
Cascade Audio's spray deadener, or Noise Killer Blue. For something cheaper
than Dynamat with the same effectivness try RAAM Mat.. It is typically sold on
Ebay, or try www.b-quiet.com.

Hope this helps :)
