You are aware that this is a forum devoted to vehicle computers, right?
ive been considering making a custom fiberglass box for my car, but i have some questions that would influence how i make it.
first, ive seen some sub boxes with padding or something in it. is this
necessary? and do you need to factor in the space that it takes up into the airspace, or not?
second, ive read that jl subs need at least 1 inch of space behind the deepest point of the sub, is it more or less for most other subs?
lastly, when mounting an amp, does it need to be open air so that it doesnt overheat, or can it be tucked away somewhere?
oh, i wasnt aware that it was just for carputers. i thought it was all car audio.
that's why you should first

I understand why he came here though, the site says mp3car.com, not carputer.com, and it has a fabrication forum. If you search for fiberglass box techniques, it's likely he stumbled upon this site. Who knows, he might even look through these pages more and start to want to put a computer in the car. This is why I am here, I started for help on using my ipod with my existing pioneer deck, stumbled upon here, and now I'm stricken, I'm putting the puter in. Maybe this will happen to him. Regardless, I have a walkthrough of the box I'm working on:
Still in the fab phase when I have the time to actually do it though, keep checking soon, it should help any noob on fiberglass in general and specifically for sub boxes.
Today's lesson: Don't knock a n00b too hard, they might actually want to be a constructive part to this community.
Most sub drivers vent the voice coil out the back and the air space is so it won't overheat, and yes more or less most subs.second, ive read that jl subs need at least 1 inch of space behind the deepest point of the sub, is it more or less for most other subs?
It gets hot, and amps have heat sinks to dissipate the heat. If it's tucked away you will have to ventilate it.lastly, when mounting an amp, does it need to be open air so that it doesnt overheat, or can it be tucked away somewhere?
Cheers! from one noob to another.cheers!
Poly-fill is good for this as is some Black Hole product out there. It's not a general statement. It's not a deffinitive "put padding in and you'll get more air space". There's a fine line and it varies depending on the material used.
In general, yes, this is correct. However, if you buy an amp that's oversized for your speakers, one that's efficient, has a lot of overhead, and is a GOOD amp, you can get away with tucking it away more than others.It gets hot, and amps have heat sinks to dissipate the heat.
