Fiberglassing Door Panels

**Curry** · 07-14-2006, 01:58 AM

Ok well, I figured I'd post this here becuase there are lots of great fabricators here and I'm sure you guys can help me along with this project and pass me some helpful tips.

And my plan as of now.

Ignore that 1st mid all the way to the left, I will not be putting it anymore. The sub will either be 8 or 10 inches.

Here's the rough sketch. (Rear Left Door Panel)

if get rid of the middle nid too.you dont want two drivers pushing the same freq. you'll get some funky sounds and cancelation

**Curry** · 07-14-2006, 02:53 AM

What if one was higher than the other? Would I still get cancelation?

Like If I put it here:

OR

I have an extra set of door skins if you would like em. I had gotten them for the same idea to paint/fiberglass em, but never got around to it. This way you could use them and not worry about messin your up.

Hey, that would be great! Can you PM me the details? Thanks!

what scott-fx was referring to is the fact that the speakers produce the same frequencies, so if you have multiple of the same speaker pushing the same frequencies you're going to have a really hot range of frequencies.

First question I have is this...why? why do you want to do this? simply for looks? if that's the case, then go with all of those speakers, but it will sound like ****.

Second question i have is this...why? Even if you're going for Sound Quality, it's going to sound like ****.

Building a frame for the door like this is a very intensive process. ESPECIALLY when you're talking about putting a sub in there. If this car is to be driven on a regular basis you're going to hate live, ESPECIALLY when you have a passenger who isn't thinking and who slams the door shut. Not to mention the additional weight on the hinges, it will cause your doors to sag and mean you have nasty irregular gaps in your seams.

If you're asking how to do something like this, it tells me that you have very little to no experience with fiberglass/bondo/fabrication in general. As such, i would NOT, I repeat, would NOT attempt this as a beginner project. You need to learn how to build bracing for these speakers, how to make your seams match, how to secure something like this and how to build it to where it will last.

Start out with something simple like flushing in a monitor into a dash, then move onto building a custom subwoofer enclosure, then a set of custom kick pannels for mids, and THEN MAYBE move onto a completely new door skin.

Good luck.

I should have mentioned it's for a show car. The sub I'm not entirely sure about yet, mainly becuase of the weight alone.

So far I've used fiberglass to mold a 17 inch monitor and component set into my trunk lid.

rather than spending all that time and money dood get nice set of component speakers.... add the 7 inch screens there sure but i dunno about goin that all out... if u do decide to then props man.... i know i wouldent have the balls to do that

**RedGTiVR6** · 07-14-2006, 01:36 PM

if you don't do the sub, it should be fairly straight forward. With the sub though, you're talking a whole nother ball game. You've got to build support to hold it there, build an enclosure for it to play in and keep the depth of a sub in mind. An 8" might be feasible, a 10" will take a LOT of work.

Have you taken the door skin off to see what the frame of the door looks like to see how much room you have to work with back there?

I'm curious, what kind of a show car are you building? Things like this aren't exactly taken on by newbies to fabrication and expected to turn out looking good.

This requires much more than just fiberglass fwiw.

I think you missed the part where this is supposedly a show car....meaning common sense has no place, and over the top, completely useless installs are the best....one reason I hate show car installs....lol
