Default Just too far enough: 2003 Wagon Build

I like car audio. I like my 03 wrx wagon, which i've had since it was 350 miles young. It's got a vf34 and morimotos and nice BBS wheels.

It also had totally average audio, courtesy of an aging JL 650 set in stock locations, and eclipse aluminum 12 (remember those?) and a JL 500/1 and 300/2. It hit ok. It sounded ok.

I decided this spring to not replace my beloved WRX, which only had 95k on it, but to redo the headlights, fogs, suspension, brakes, wheels, etc, plan for the timing belt and ponder a new radiator. To quote Madonna, "I'm keeping my baby." We've had a lotta fun times together.

But the audio sucked. So I fixed that. The components are a tweeterless Hybrid Audio setup where the dash carries everything from about 250z up. I wanted the 8.75" L8 mounted firmly to the door, not the panel, and did not want to foul the footbox whatsoever- I wear a size 11, and double clutch and do all sorts of footwork down there, so kicks were right out, been there, hate it. I'm also not impressed by overweight, brittle work stuffed full of bondo and kitty hair, so everything is pretty meticulously laid up. I paneled and CLD tiled the doors while I was in there. The Sub is the very awesome DC Audio L3 15", which despite it's oceanic LF output, sounds amazing in it's MFD test box.

Some of the pics have funny perspective and I didn't really want to write a narrative of a somewhat self explanatory process, so here's a bevy of pics, and if anybody is inspired to ask anything, I'll fill in. I started in early June and want to get everything settled and be sure I'm happy before I start the finish phase, so yeah, theres a test box and some tape involved right now, but it'll get cleaned up over the next few weeks.

Also, I'm powering everything off the old amps and a really nice classic rockford I had sitting around, mounted under the seats. It's adequate, but twice that (and a new alternator) would be juuuuuust too far enough. That will magically become- most likely- a zapco z150.6lx and Zed Minotaur, once various sales of other stuff loose up some cashola.

Thanks for checking out my thread!I hope this inspires some imagination out there-

I guess it's time for a quick halftime before the back half of the project gets under way. I can't really wait any freaking longer to build an amp rack (I'll go get materials in the morning) but first I had to get the front end finish work close enough to not hate.

I had originally planned on using a flocculated paint to finish the pods, which leaves a little texture and a nice matte finish- with SEM 15013 Landau Black- but after I got one done, I realized I'd have to do the pillars to match, and my pillars are kinda shot from various tweeter / gauge / I'd have to do bodywork to get the paint to lay ok....

Oh and I hated the way it looked with the dash, which has some plasti-dip, and still looks good. I have about 5 yards of black microsuede which is supposedly UV grade, so I wrapped the pillars and the pods.

The first few are doing the bodywork so the paint would lay flat, and then I realized that it'd suede real well at that point. There is compound curves on my left pod, so there is a fat seam which is visible from through the windshield.

Next year, when I have some cash together again, I'd like to have leather seats done. I'll do the door cards and pods matching at that time.

Passenger pod, In black resin:




I won't use it to make real parts, but I love bondo to get things flat and sexy, and it's smooth lil sis glazing compound is reallll smooth...Pink is gazing, blue is filler... Passenger and then driver pod, respectively







came in with just a little sanding






Did Passenger's in high build primer, which I wet sanded. This entire step was skipped on the driver's side one.



A lil test fit yesterday afternoon...

A test fit in the middle of the night

After driving to coffee this morning with nothing over 250 hz, which is where my door speakers crossover, I began to really miss my highs.

I did the body work to the pillars to get them to suede smoothly, which wasn't interesting enough to take pictures of, and spent a few minutes getting all the various wiring and air holes to line up- they acoustically need the space of the pillar and dash to play well. The pods have defroster ducts built into them which aren't hooked up right now, but I wanted to make sure they would when I did that. The boost gauge hose was, of course, 3" shorter than convenient.

Pods, Pillars and Scoop: a still life.



SOOOO DETOUR. I've always wanted footwell lights, but not some switch or bs. On when any door is open, especially now that I have an enormous speaker hanging out of my door. You can kill the dome light / door still, but the footwell lights still come on.

This is partly because of my laziness, and the clever way subaru supplies their dome light power when the door is open- at the light. In lieu of dragging more wires around, I just probed the light controller's feed at the dome light and grabbed it's switchleg and power at the a-pillar. No fishing or funny business- blue and blue red tracer.

yellow is door signal on dome light harness



jinkies I use cheap speaker wire for everything!




The footwell lights themselves are some very cheap "Pilot" 194 9 LED types. I needed one single 194 for the boost gauge, and since each pair with a socket, (one!) I'd thought, "why not just get a bigger set and wire in the footwell lights?"

But, here's the first pics, I'll take more tomorrow when things are a little more cleaned up- want to replace the screws in the drivers with black ones. LOVE my 13 dollar footwell lights.





thanks for reading!

Thanks for the positive comments! A few people who have looked at it today seemed very impressed. All I see are the seams and things I know aren't done yet or perfect (why haven't I coated that left pod's MDF ring? It'll swell and I know it.) but it's flying towards being to the point that i'm happy.

The two knobs in the radio hole are, from left, the bass eq level from the jl 500/1, and the system volume control, a nanopatch+. The source is the iPhone that lives in the car by the wheel, which is jailbroken and can be controlled additionally by the magic trackpad down in the "fireplace" in front of the shifter.

It has very slight channel separation issues at lower volumes but it generally transparent and extremely convenient. It's HUGE! That gets updated mid september.

Off to tap plastics!

You are obviously not afraid of the fiberglass, nice work! Wishing I had the patience to play with fiberglass that much, lol.

Thanks! I'm by no means an expert with composites but I'm getting there. The mess is a bit off-putting, but I don't mind the itching and extra showering. Mask and Eyewear is essential, and a great vacuum is great too. Also- a lot of wood is just as bad (MDF is SUPER dangerous) as fiberglass. I've got more patience than cash ; )

As for the door panels, I'm interested to see how that happens too! I still stand by my decision to make the speaker mounts part of the door instead of the panel but it's certainly making the last step a little tricky. I ordered some grilles to keep things and feet out of them for the moment and have a few ideas, but I'm gonna let them simmer before I trim them out. I'll fab the grilles for the dash speakers first, I think late next week?

So, it's obviously amp rack time. I kind of feel like I'm going to be making some concessions in the hatch already, which will be apparent in time, and this car works from time to time, so I feel like making use of the natural flow of the car the best I can, which is a line of rectangles sunk down between the shock towers. I know ballparky what kind of power I need to make the setup do work (about 1.6-2kw) and have good headroom, and although I don't own any of the three amps I'm planning to use yet, their manufacturer publishes good info and I'm confident in building around published numbers, so I left myself 280 thou margin of error.

To the saw!

I want to clone this pile of thing but made of oak and filled with amps. What amps? Not what I said before, that plan turned out to be horrible, but I can't say until they're sitting on my floor, just a religious thing- I don't wanna be that "I got this that doing that" guy without the cheddar.



so ends first, just grab the digital caliper...



and then some lateral support (37" fits just perfectly, btw, so that's 36" internal)



and then a nice, simple shelf for everything to sit on...



And around midnight realize that two of the amps are about a quarter of an inch taller than the third, which is going to necessitate a bit of a rethink.

I did the ol' sits n thinks and reasoned that, since I already know how the top will be finished, and NONE of this is going to be visible, it's ok to build this bottom section as minimally as possible, as long as it'll trim well. I still need a piece of aluminum which will actually constitute the top amp mount...



This also shows the rear supports, which got cut to height to sit on the center rise and clear the various tank accesses. Oh, yeah, had the filter sock changed last month.

Here's the depth / height template (I call them "bogeys" and this one is 20 thou proud) for two of the amps I'm using, which now dutifully sits 200 thou under the apex of the top frame.



and since we're on the subject of dimensionally accurate fakes, here's a cargo-cult subwoofer!



PRESTO CHANGEO!



thanks for watching!

Little busy so I haven't got too much done... Ordered two of the three amps, they should be here late this week, so I'm still in a bit of a hold, but I was able to root about the local metal salvage and found some very nice materials that will be part of this soon, and sell an awesome old downpipe I had in storage, so that I could actually proceed with this insanity.

I needed to make a pair of struts to support the center load of the amp rack lid. I used a piece of .125 "L" aluminum

first, a little cut



then a little electricity




and then, a **** ton of elbow grease, since I hate the mess wheels make (the unpolished piece in back for comparison)



and one step closer...




and thats all for the night-

Well, two months isn't too long. I guess a vacation and some textbooks will pass the days....

There's a lot going on in this build. There's still an "eggshell" sub box half cast, some dash work, some more dash work, I have to make a battery hold-down / fuse rack still, but the major hurdles have been jumped, so I figured it's time for a little pugilism. I didn't get the power cables until mid september, sooooo...

I needed some space for all the power and fuses, and also for the DSPs and the preamp(s) and power switching stuff, as this build doesn't use a "head" unit. So I got some plexi and some nice 10", double bearing slides, and put them under the seats, where the amps used to live.





Something like this, with the seat out...



Oh Good Grief.



I love Copper. Don't let anybody lie to you: Copper is king. SHCA OFC 1/0. That silver cable will the bit of yellow tape is old school 4ga, and just looks puny!



1/0 to the fuse block, then 4 to the sub amp and 8s (the blue and red) to the other amps.




these cables aren't held down yet, which i did invisibly with the magic of museum wax.



All dressed up!

The amp rack is done and installed, with the amps-

Rockford Fosgate Power 1001BDCP, Punch 400x4 (bridged) for mid bass and 400x2 for the highs. I'll take better pics tomorrow and share- but this is what I've been up to tonight and it seeeeeeems to be coming together...







I'll just point out that it's an axle, not a bracket ; )

nnice work man... tell us about this "tweeterless" set up? The L3 is running 250hz and up and no tweeter at all? I know the L8 can play up to 250hz no problem those are beast mid basses.

post some pics of the amp rack.

Good golly, so long to update, but it's a good confluence of progress and time to do so tonight... I see a request for an amp rack pic, which I'd love to go take, but my bike rack is on. Here's some glimpses that aren't great... Work has slowed to a crawl during winter and the semester...





Tx wagon, the full ranges work exactly as you think and sound great, though I wonder if I haven't heard smoother super high frequency, or if I'm listening to my windshield. It's just finally coming to the point where I can put real tuning to it, and of course, there's a lot of subjectivity, but I generally feel like they're pretty good, overall, which makes them extremely good for car audio

I tried a set of (vifa?) full ranges from parts express in dash pods with my old JL 6.5 in the door and it was 85-90 percent as good as this, just about -5db and less punchy.

I occasionally feel like the car is a set of really good near field monitors, more than a room. I frequently don't run the sub.

Bleagh, more pics.

OK, so I needed to control the DSPs somehow, and I wanted an internal media server onboard. So...

I got some wood and made a sketch



and some hinge pins and arms



sized up everything...



The mac is a 2007 MBP 2.33 swapped with a 230 solidstate and 4gb of ram. Its more than fast enough for this and runs like a champ (and is worth less than a nice shirt)




It works, so time to make it out of nice parts. BTW, this thing isn't going ANYWHERE like this.



and some alumaweld (no they cannot be disassembled, and yes my dryer is kinda gross.)



assembly is always fun



reflection in the amp rack cover.






BTW, it's bolted to the back of the seat with 1/4-20 nut plates and allen bolts. The entire thing can be installed or removed in well under one minute.

This is a great time to admit, that at this point- which was around the holidays, I could trick the setup into sounding good, but it wasn't consistent, and a bit noisy. I didn't like how the DSPs volume controls worked. Volume control is the biggest issue with massively multichannel setups like this (5 channels, three volumes) and not having noise, and full dynamic range. So, I scrapped the earlier preamp setup, and went to FOUR audio control overdrives: one before the dsps, and three after. The volume is controlled at the three post OD+ boxes, while one handles the pre drive and brick wall compensates. Ie, Dr. Dre's 2001 is like 10-12 db louder than some older recordings. Being able to vary the pre-drive allows me to punch up the dynamic range on older stuff.

So I needed a place to put some of this stuff.


This OD+ feeds the dsps



Made a lil clamp platform and got some threaded rod...



Btw, a little black shrink-wrap over threaded rod looks great.

I don't have a pic of it installed, but thats ok, you've seen a 02-07 WRX glovebox.

Got a little more upholstery and programming to do but...

the pop out screen is alive, and may even be coded this week. Im not a very good computer programmer and this sketch turned out to be much more complex than I thought: it needed to sample and interpolate the feedback data from the motor in a way I hadn't even began to think about. I had to wait for a few weeks to get a custom cable from motion which actually pulls the screen up into position, but it's next to be completed.

The last video you could see it moving in and out, and it needs a lid, and some way to open it...

so I got some 1/4 'lum-'lum rod, and polished it..



After heating it and bending it over a socket bolted to the table, I needed to drill it for a 1/8" axle, so I made a drilling fixture...



and laid in the axle. It's very straight, this is a horrible angle.



and this is how you drill an 1/8" hole in a 1/4" rod with basic tools : )



plexi + hole saw + file = pulley




which finally makes...

My doors, they sound great, but are a little, i dunno not quite done, can't hold a computer keyboard and ****.



made the initial shape, with the dash, and got some ideas





Took a break for a minute to go shopping



got some cardboard, which makes a superlative composite





when making cardboard panels, it helps to have clamps and weights around (buy these wheels!)





checked for fit.. the keyboard has a little bracket it sits in, at a diagonal, so it's easy to reach



primed, bondo, glaze, check fit
