Big Box how many layers?

Hey im making a glass box for 2 Rockford Fosgate Punch Hx2 15s with a volume of about 2.5cu ft. per chamber but it will all be 5 cuft all together because there will not be a wall inbetween the chambers. How many layers of fiberglass will i need to make sure this beast doesnt flex? Should i use coremat? thanks for the help. dream it, build it, fiberglass it

1/4" should work for most of the enclosure. Flat areas should get more reinforcement.

1/4 is thick enough for 2 15's in a 5 cuft box? dream it, build it, fiberglass it

3 layers of 1.5 oz chop, 1 layer of 2 oz coremat, 3 more layers of 1.5 oz chop. If this isn't strong enough, wait 24 hours and layup some more glass.

iaudio - how much resin would u suggest for just what u said if its a 5 cuft box (back will be wood, about 36 inch x 18 inch)?dream it, build it, fiberglass it

With the box I'm just making like sort of half a box in the back to screw the 2 amps and a cap into, thats what the wood will be. I wanted to display the amps since they look good 1001bd and 301x by rockford but cant find an easy way since its so hard to run the wires thru the box without running powers next to rcas and all that sh*t. thanks for the info though dream it, build it, fiberglass it

Sometimes you can get away with running RCAs next to power wires. You just have to find out through trial and error.

mix 1/2 bondo and 1/2 glass..its thicker and seals great....
