Awesome work, Geo!!

Labor of love


For the life of me I can't figure out why I am applying body filler to a sub enclosure that will be hidden under the floor of my vehicle. I don't NEED to be perfect here:



Sanding sanding sanding sanding. Re-apply body filler. Sanding sanding... Well, you get the point.



Grab an energy drink. Time to lay down some primer:







Primer complete. Time to lay down the paint. This stuff is weird. It goes on and then gets darker as it dries:



Painting all done:



Yep, still fits



About 1/2" clearance between hatch cover and the top most part of the speaker baffle:



Just about 1-1/4" clearance between subwoofer cone and cargo area hatch cover. That should be enough space for the Sundown Audio SD4 to pound out the bass:

Now lets finish this sucker up.

Add adhesive backed closed cell foam to the exterior of the box so it does not rattle and vibrate in the trunk:

Now add a carrying strap for when I need to remove the sub:




I double the strap material over itself so it could be stronger with a screw driven through it:







Use the proper size center punch to mark screw hole locations:

Where was I?

Oh yeah, drilling big holes in sh!t.



Seal up the hole with silicon:



Seal the other side so wire is not vibrating against sharp fiberglass edges:



Now stuff the box lightly with some polyfill:





Wire up the sub. I used XT60 disconnects here because I might want to try a few different subs. This is the fast way to switch them out:



Use wire ferrules to make connection with the push terminals:



And there we go:






Just a few minor adjustments in fitment and we should be golden.

BTW: I ran a quick listening test before my sons baseball game tonight. Dang this little sub hammers.

Problem. My cargo lid does not close all the way because of this plastic handle that hits the top of the sub box:



There is about a 1/4" gap. I could either modify the handle, or...



Raise the floor another 1/2"







Nothing like making a mess with your router outside just as the sun is setting.



Drill pilot holes and re-install in vehicle (refer to my earlier post to see how I installed these).






I now have an additional 2" of clearance under the cargo floor. I can fit a deeper subwoofer if I want.



Cargo hatch now sits flat. The handle does not touch the sub enclosure any more. I even vacuumed out the trunk for this photo .

So now that most of my install work is done...

nice work, I hope you are proud of that.

Won't motor noise get picked up by the mic?

[erinh]

that looks familiar.

Steve, not when you're blasting PN. SNR.

Those fan motors aren't as loud as they used to be. I was a bit surprised when I ran the motor of my new fan (living in Phoenix, AZ, you have lots of fans) without the blades. Really quiet!

This sucker is whisper quiet. Not much to pick up over pink noise or a sine sweep.
