Assembling the fuse block

1/32" thick neoprene foam gasket on the amp cover

Turns out when you lower the rear seat, the seat support folds down and laid ON the cable as it was previously ran.

40365996092_948bc4f600_b.jpg

We pulled the cable and cut a huge hole in the floor and used some plumbing pipe in to protect the leads from everything.  Custom notch using the dremel.  Still need to backfill with silicone.

Underside

There is so little room everywhere on these Jeeps.  This was the best way to route the wire to keep it as high-up as possible.

40365998432_fa035192e8_b.jpg

This is how we had to route the cable to clear the fold down seats

Installing stuff

Decided to rip out the previous lug post.  

40410592941_2afdbac4e0_b.jpg

Made 16 leads look clean

39514200595_0b8aa53a3d_b.jpg

New posts for the leads

Bottom of box

The PAC AmPro remote wire stopped working, so we just checked for a proper ignition-on fuse and added an add-a-fuse for the rear relay.  Funny thing is we added the circuit to the horn fuse in this pic.  We didnt know why the amp wouldnt kick on.  Then I said "honk the horn"... the amp-fan kicked on for a moment and I realized this was only hot when the horn is honked.  Always check for both ignition on and ignition off when adding a circuit to a fuse panel.  We have since moved the circuit to another position.

Ready for gain settings.  I always like to know at what voltage the amp starts to clip/distort so I usually run the DD1 with the DMM.

26539670478_ca8bce395b_b.jpg

1/8" neoprene foam for the box back/port (didnt get a pick of the back installed but its shown mocked up on a previous page.

40410606641_351a83ff2d_b.jpg

So this is a temporary chassis ground.  This same hole will be cut to a larger size once the grommets arrive so that we can ground direct to the frame rail.

26539667908_6794d84ab3_b.jpg

Got the box inside and tilted forward for hinge installation

Hinge install

Folded down

Final check before attaching sub leads.  We're expecting a little bit of impedance rise so 1/3 ohm is fine.  

39699925344_a0ed2e4b79_b.jpg

Coiled the wire so it lays nicely when you close the lid

39514202085_01c9e235bf_b.jpg

Yep lays in well

40410595421_9af901d636_b.jpg

And then we drove around and jammed for half an hour.  This little fourth order gets down!  Time to break these 8s in before finishing stain and other details.  Definitely more to come soon.

Got a VM-1 and OM-1 for the build.  Now to make some sort of pod that houses them and can incorporate some tinted acrylic to dim the bright SMD/D'Amore displays

Just going.  We'll figure it out when we get there.

Flush trimming the acrylic.  We're dealing with less than $15 in parts so if it doesnt work out, we'll start over.

Keeping the edges looking fancy

Mock up

Video of the 8's banging.  Dirty and unfinished, but it plays so we're breaking the subs in before we make it pretty.

My buddy Herb marking the support stand for his D'Amore display

Some cuts and holes later

Conveniently used his GPS mount bracket that is made for the Jeep.

First layer stain.  

26886286038_0ae32607ca_b.jpg

3 layers stain and 3 coats clear.  We did a 4th coat of clear with 800 grit in between and it looks even better.  Need to snag a shot.

26455969107_f01474e318_b.jpg

 

So plans changed a little on the 4th order...  We pulled the back panel off (including the port, see previous pics) and decided to build an add-on section with more box and port volumes.  Went from ported box volume of 4 cuft to 6.2 cuft.  Increased port area from 56 sqin to 117 sqin.  Sealed side remains 2.5ish cubes. Hopefully tuned to 35ish hertz.  Per Triticums port area calc, we should be in the 'optimum' range, yielding 22m/s port velocity.

The box cant tilt as high now, but we can still reach the vitals.

Here's the add-on by itself without a top or back panel.

41595353062_5a677bf9ab_b.jpg

Gotta make that 90deg bend smoothly

41595349352_cec481308a_b.jpg

Routed every sharp edge in the box and port interiors.

41595348062_6a39b4a712_b.jpg

This is where the magic happens ;)

41595345012_01b0a691fb_b.jpg

Gotta install the top and back panels next weekend, test to see where we're tuned, and see how it likes power with more box and port.
