Jayhovah's fiberglass sub box build log

Jayhovah · 01-10-2018, 08:58 PM

Well I stopped by the fabric store and they didn't have anything that I liked.. I called up a local upholstery supply shop and they recommended Allsport 4-way stretch vinyl for this project...but also informed me they didn't stock it and suggested I buy it online. Found some on eBay for $10/ft so I grabbed a couple of feet - should be plenty.... but won't come in for a week or so.

Ah well.. it will give me time to clean up the garage (so I can park in there!) and install my amp.

Back when I was in high school, I worked at a commercial upholstery shop (seats for tractors and semi interiors). We would sell scraps to locals for cheap - sometimes free if they didn't mind doing a little dumpster-diving. There may be a similar business in your area.

This is probably the best advice in context.. but I went ahead and ordered the vinyl and, to tell you the truth, I have been neglecting some other things to spend time working on this project so taking a break from it is probably not the worst thing in the world. =)

little update.. I figured since I bought more body filler for the Milk BoneZ I might as well use it.. So I just cleaned up a couple of the low spots..

After blocking it down I was finally happy with it. I decided to fill a couple of the little pin holes and bubbles even though I doubt any of it would show under the vinyl... but what the heck.

Just need to sand those spots down (<5 min) but I am pretty much ready for vinyl! The stretchy vinyl comes in Tuesday so sometime next week I'll cover it.

How do you guys seal your speaker cable going into the box? I usually add a terminal cup but I decided this time I'd rather have a pigtail and connector.

My first impulse is to use a ball of epoxy putty. I'll probably put a knot in the cable inside to keep strain off of the seal between the cable and putty.

I usually just use a bit of silicon.

RonRizz · 01-13-2018, 05:07 PM

Same. Knot it, and silicone it.

Jayhovah · 01-15-2018, 11:04 PM

One last test fit after sanding and cleaning. Ready for vinyl at some point this week. Still need to install my amp as well... Happy with the look so far.

Love it

Looks like they're coming along nicely!

Vinyl arrived today and I couldn't wait to get it on... While it's the most successful vinyl job I've done (only the 2nd) I'd only rate it a 7/10. The vinyl on the curved side finished a little lumpy because I dicked around with it too much and the contact cement started to wad up underneath. Not terribly noticeable unless you are really looking and not bad enough for me to tear it off and start over. Overall I am really happy with it!

RonRizz · 01-17-2018, 03:42 AM

Looks fantastic..

Fuzzzy · 01-17-2018, 11:40 AM

Absolutely awesome!

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.

Jayhovah · 01-19-2018, 07:54 PM

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?!
