    you should do at least 3 to 4 coats for sub boxes. . . with things like amps or interior, 1 maybe 2 will do. thinner walls = a box that WILL break = a waste of time!

  2. MrGman2000watts says:

    what is your hardener to fiberglass mixture? and for the body filler what is your mixture. . . also what are the brands of the materials that you use (fiberglass, body filler, hardener, everything). . . and last question, where did you buy your supplies?

    Nice work guy. I own a shop in tennessee and most of the time i put the actual fiberglass on the inside of the box so i can do the bodywork with fillers on the outside for me it seems like less work that way and i use alot of hot glue to support my ring before i use the mold cloth it works great and comes out easy when done but nice work

    Yeah. it is tuff, some speakers its good with and some its not. If you listen to death metal it will help them to not “bottom out” because of the constant bass. None ported could be good for rap or music thats not as upbeat. it also depends on airspace where you have them placed. Just keep messing with things and you will find different things out. It will not hurt if they do not have ports. You just might not be able to crank it as loud.

  7. redhotcustoms says:

    Ah, I see. So, I take it the ports enhe the sound? Can a box still work without them? I’m trying to learn about custom audio, it’s one of those things i’m clueless about but curious to learn.

  8. thegoatbird22 says:

    they are ports for air to escape. L7′s are bad ass in a box with ports.

  9. redhotcustoms says:

    So, what was the rectangles at the bottom for? Just looks or did they have a purpose?

  23. McKinoza says:

    Awesome box, so normally a wooden box would be 5/8″ or 3/4″ mdf all around, but on these how thick do you build up the fiber/bondo? Can you get away with thinner walls using this material?
