Jayhovah's fiberglass sub box build log

Jayhovah

Added the cabling for the sub.. I ended up using epoxy putty only because I happen to have some laying around. Seems like it will work well.

Also started installing the amp. When I installed my boost gauge I had the foresight to run an 8ga cable from the battery compartment into the cabin at the same time... just left it coiled up behind the kick panel in the passenger footwell for a rainy day. Likewise when I installed my headunit I hooked up an RCA to the sub preamp and ran the remote turn-on - left it coiled around the base of the shifter.. Thanks Jay-From-The-Past.

I'm off work tomorrow so I should have it up and running at some point! Pretty excited to finish this one up and move on to the next project of installing some catch cans in the engine compartment.... That will be the last Z project for a while as we are moving into our first house in a couple of weeks and remodeling projects will take up most of my free time for a bit.

Finished up this afternoon! Rounds out the low end nicely. Very happy with how everything turned out.





Testing...









I ordered some connectors for it.. but they haven't arrived yet so I just did twist/tape job (I cringe just thinking about it) until they come in.

What do you guys think?!

Thanks! I honestly have no idea... I figured it was probably in the usable range so I didn't worry about it.

It turned out really nice, better than you initially thought it would I bet.

axmea?

Nice work J. All that masking, cutting, and sanding paid off. Now go make the left side Btw I used OG PPIs (ART v2) a long time ago and they are bullet proof.

Thanks everyone! Best one I've made thus far I think. Thanks in particular for the advice along the way!

I think if I were to do it all over again (which I wont lol) I would have rounded off the side face completely instead of squaring it up to the strut bar and also shrunk that side in little closer to the side of the car so the box tucked into that nook a little more. Those two changes may have given up too much volume though... but I think it would have looked a little cooler.

C'mon, man! Don't you want it to be perfect and absolutely the way you want it? I'm sure there would be a strong market for your "factory seconds"

Dibs!

j/k. Great work!!

Awesome job man!!! Been thinking about adding a fiberglass sub box in my z for a while now but I don't have the skills, tools, or the know-how to do it. I've been looking at the corner box made by Wicked CAS but I prefer the look & location of this one more. With that said, anyone wanna make one for me??? LOL

Jayhovah

One of the best parts of glass is that you don't really need much in terms of tools.. almost everything you need is consumable. I did my first three fiberglass projects in apartment parking lots and the only real tool I used was a dremel for trimming. It's really pretty forgiving and easy to learn.

Really??? That's awesome!!! I've always wanted to learn how to do cool things like this but I'm always fearful that I'll mess things up horribly. From the looks & sounds of it, I'm 1000% positive that you're much more handy than I. Anyway, I'm over in Orlando so if you're ever looking to share some knowledge and/or experiment on a z then please let me know lol. I'd be willing to offer compensation. Cheers!

You gotta start somewhere and with things like this you will improve drastically with experience. Just take your time, watch a bunch of youtube videos, and ask a ton of questions about anything you don't fully understand.. There are forums for things like this like diymobileaudio.com where you can get great advice from people with loads of experience and even some pros.

As long as you do a good job of masking in your car (and put plastic sheeting everywhere so you don't end up with a resin mess in your interior) then you can't really ruin anything. At that point, all failing means is that your project is not coming out like you wanted and you are out some time and a few bucks (but will have got yourself a ton of experience).

In my 5 fiberglass projects, I have probably started over and thrown molds in the trash 5 or 6 times. Even now I am learning a ton with every project and can think of several things I would do differently with the one I just made if I did it all over again.

I think 90% of "being handy" boils down to two things:
1) Willing to try, fail, and retry.
2) Having patience and thinking about every step of the way (go into each step with a plan, finish each step thinking about how you might do it differently next time).

If you want to do it, then go for it! You really don't have much to lose,and the end result is very satisfying. The only tips you need to start are WEAR A RESPIRATOR and take your time.
