Back. Build for 2 sundown x2-15's

[L1ttlet]

So back in December I took on a build to build a box for a '75 Cadillac. It's been a few months and I'm finally nearing completion as my job and clients job intervened. So here we go. There is about 4.4 cubes per sub after port and displacement, bracing and fiberglass resin coat. It is 1.5 inches thick. There will be a 3/4 inch plexiglass viewing window where the hole is.

Some more updates, 85% done. Plexiglass and leds realy make this box, very proud of this one, although my fiberglass resin coating on inside of box could use some perfecting.

You do realize that using resin inside of the box isn't  necessary right?

yes, really not going to provide any extra strength to this box but it sure looks nice, but when I first started it 5 months ago I thought it would. Lol.  next time just do a rattle cab clear coat or something to make it shine and be smooth.

not necessary, but if you compete in SPL it would be a small benefit - +0.3-0.5 dB... coefficient of friction is smaller than bare MDF or plywood

Ive used resin and some times resin and mat in almost every box ive ever built its cheap and not that difficult and definitely adds to output.

How much does it add? .1 db?!

Not if your running 1000's of watts. Just leaning your seat back will add that.

If you are serious SPL competitor then every 0,1 dB is important! It happened that I have lost for 0,1 back in 2005  in finals fighting for World record in StreetB
