Resin is the part of the mixtures that is the smelly thick liquid. The hardener ( MEKP )is the chemical additive that will make a chemical reaction with the resin to start the hardening process.

Personally I don't use that brand, but I think it's a matter of opinion. If you have access to it and it's relatively cheap to purchase, I don't see there being a problem with it. As far as the wax runor, I think that's kinda like water in gasoline...... it happens, but not every place is doing that.

Hi everyone

As a newbie, Ive found the info giving in this forum extremly helpful. But i do have a couple of questions in which might sound stupid.

Im hoping to build a box for 2x12'' visonik subs (700 max each) as well as an amp. I would like for it to be similiar to the one jeff built, with the exemption of two subs. But somethings are unclear to me.

How big should my box be?

As well im hoping to build an amp rack (for another one of my cars) out of fiberglass it is to be placed in front of my subwoofers. Ive made a mold out of wood. Can i just proceed to put fleece and add fiberglass, then take separate the wood from the mold? Sorry if this question might sound stupid but help and advice would be appreciated

Thank you

Take this link and it should help you with the volume calculations for the enclosure. As far as the second question, you shouldn't need to remove any framing from the projects. Leave all the framing that you have to give the project structural strength as well as it would be an absolute bear to remove the framing after it's been resined.

Ok, im currently working on my project, decided to make my box as similar as i can get to the one shown, picked a 12" speaker and a small amp to power it, everything is going fairly well however I have a few questions....

1)How did you mount your speaker to the enclosure? If you made your holes in the first circular ring did you drill through the fiberglass? be very specific if you can.

2)Just checking but you ran your wires to your speaker and amp above the enclosure and then made a cover to hide the wires? I cant really tell by the pictures if you attempted to run the wires through the enclosure.

1. I pre-drilled the mounting screw holes for the sub onto the actual enclosure and mounted the sub this way. Depending on how you made your cover peice to cover your amp and subwoofer, you can have the sub cutout covering your mounting screws or have it cutout the same size as your subwoofer.

2. I just ran the wires under the cover to the amplifier but if you didn't allow the thickness of the wires into your design what you can do is drill out two holes on either side of the terminals to pass through your wires. Make sure that the holes drilled is exactly the same if not a hair larger than the wire your passing through it. Before you place the sub back into the enclosure and run the wires, make sure that you use some silicone on the inside of the sub wire where it touches the sub surround to ensure a sealed enclosure.
