A neighbor has a body shop and hooked it up by rewelding the thin sheet metal at the windshield pinch seam

I didnt know how strong it would end up, so I asked him to leave it in primer in case I have to reweld it later.

Around this time, I bought a welder and learned to weld so that I could build a stripper pole to stop the windshield from flexing

Had it powdercoated by some cool guys at Advanced Powdercoat in Houston

Is this legal, lol? I got a warning once for having an air freshener hang from the mirror

LOL the guy that honored my state inspection really liked the setup.  He didnt have a problem with it, or with the 12 cubic foot box blocking the view out the rear window!

I love this build, some awesome craft work in here!1f619.png

Since I don't recall from the last thread, have you metered this setup yet?

And how did you get those impedance graphs on the first page?

Thanks man. Hopefully some more serious progress will be made this weekend.

Metering is of little importance to me.  Sonic hasnt had an SPL measurement.

I used an IM-SG for the impedance plot. That measurement is way more important to me because its indicative of how well the system is playing across the frequency spectrum.

Removed the torsion bar that helps lift the trunk.  Gonna install struts soon.

Added a splitter at the back of the port.  I kept it small so that I dont lengthen the port.  Hopefully this helps with efficiency a bit.  I'll do an impedance plot to see if it helps at all.

Then I went balls deep on prep work.  Needed to smooth out the interior since you'll be able to see inside it now and needed to remove the 'honey' colored stain on the face.

Made some 'wings' to seal the wall off.

Also removed the cables that run from the front battery to the rear battery bank.  Homeboy Juan at 12V Metalworks is whipping up some nice fuse blocks for me.

Got a layer of paint on the inside.  One more layer tomorrow and then I'll be done with the inside!

Also got a thumb scroll bass knob from SPL Cartel.  Thanks for the recommendation @Mr DeeBeez!

Love the build man. Looking great so far! What are your plans for finishing off the front of the wall? Different stain? Or paint?
