Hi All,

So I've been away sick most of last week and pretty much dragged my butt around most of the weekend. I hopped on to put up some pics of the progress the rest of the team made while I sat around and snoozed. Well I just assumed that this thread would be on Page 4 or 5 by now and couldn't find the damn thing!!!

Had to use the search function to find it and you guys had bumped it back up to Pg 1 again!!!!

So here's what's gone on this past week.

Bec used some old Stinger RoadKill Spray-On Sound Deadener that we had at work to coat the rear door trims:

I sat on a stool and tried to give Glenn the idea for the rear battery/amp rack so he could rough it together. The plan is to have 2x Stinger SPV69 batteries down in the spare tire well, with another row of 6 across the rear floor. Add in the 1 under the hood and we have a total of 9, that's pretty much 775CCA and 69Ah per 1250w Monoblock. Of course we have a few 4channel amps (300w RMS ea - 4x 75w). That means a total of 621Ah and 6,975CCA in order to run 12,150w RMS or amplification.

Next we (and by we I mean Glenn) started working on the Amplifier rack. The idea here is to have 4 shelves with 2 amplifiers side-by-side per shelf. Then we will have a single amplifier at the top on display. So we took a tip from the boys at Phoenix Gold in the Philippines and removed one end cap from each amplifier and butted them together to save a bit of space.

Glenn also quickly knocked up some brackets that bolt into the stock seatbelt locations, the back of the box will bolt directly into the battery/amp rack which will then bolt into the chassis of the vehicle.

Very nice work, Scott. Much respesct to a guy who seems to be able to manage a huge build and life responsibilities simultaneously.

On Sunday I started feeling a little bit better, and got started on the B-Pillars. The original idea was to try and leave them with enough room to mount some speakers in firing backwards out of the rear doors, but with the door skin mounted up there just wasn't enough room. So then we just needed to shape them to follow the original B-Pillar shape while allowing the seats to sit all the way back against the box.

So since the speaker wouldn't fit in the B-Pillar we needed to look at our options for the rear doors. The original idea had a 20" PC Monitor mounted up in the rear window area and some amplifiers mounted below it. We wanted to have it so we could roll down the rear window and have both video and music coming out of the rear window. Now that we have to find a place for the speakers as well, we can't have both video and sound coming through the rear window. Here in Australia there are a fair few charity cruises and other car shows where a cruise aspect is involved -- So the question is, when cruising around at events is it more important to have SOUND or VIDEO???

Our current thought it to go towards sound when driving and add the video component when parked and doors are open, so we did all the test fitment for 3 speakers up top firing out of the window, with the PC Monitor mounted below it along with an amplifier added for good measure.

Like our official 3D rendering of the product placement?!? Opinions on this layout? It's definitely function over form in this case...

That's all for now, but more progress during the week!

Cheers,

Scott

HaHa Thanks for that!!! And I'm sure my wife would disagree!!! I'm just glad she's right there beside me getting dirty along with our little 2-1/2yr old son!!!

As for any ability to "manage" I'll chalk that up to also being Canadian Eh!!! (born and raised out in BC)

Hi All,

Well we got a few minor things accomplished during the week...

Made a quick start on the RCA splitter boxes. The plan is to have some hide-away boxes that handle the RCA distribution, so I ordered some mountable project boxes and a bunch of decent quality RCA ends and started knocking things together.

For the subwoofers we need 2 channels in (L&R) and 18 channels output (L&R) to provide signal for the 9 monoblocks. We could have used the RCA pass-thru on the amps, but then the RCA's would have started to get pretty messy in out amp rack. For the full-range amplifiers we needed 4 channels of input (Front L&R, and Rear L&R) and a total of 16 channels of output.

So here's the start:

Another BIG win this week was the arrival of the AudioControl EPIC-160 which will provide the processing and increased RCA voltage for the Subwoofer amplifiers. We'll be running the AudioControl MATRIX for the full range amplifiers once they arrive.

So today (Saturday) we did a BIG run to Bunnings (the Australian version of Home Depot) and got stocked up on supplies, then it was back home for toasted sandwiches then out to the garage.

Today we tackled the speaker pods for the top of the box. These serve to block off the gap at the top of the box up to the headliner, and also to house a couple pair of Ti5CX 5-1/4" coaxials just for a bit more uhmmmph up front...

After the standard carboard template we traced it out onto a piece of 1/2" ply and then made the central roof piece and worked out the angle follow the contour of the roof as it slopes down towards the front windshield.

From there it was time to thicken up the edges to make them blend into the B-Pillars a bit better, ended up being 4 layers of 1/2" to get it right...Gotta love the BIG flush bits for the router!!!

Once the thickness of the edges was sorted, it was time to blend them into the central section, with some nice flowinessness...
