Was outside literally the whole day. Got my wire ran, soldered a few remaining terminals, got the amp rack in, amps wired up temporarily. This is what under my hood looks like now:

Lololololololololololol, here's the inside of my amp rack:

That's only temporary. [MENTION=33]PapaGeno21[/MENTION] is making me buss bars right now, should have them by next weekend, and everything will get cleaned up then.
But here's a quick, blurry pic of how it looks:

Didn't get speakers or anything wired in yet, that will be tomorrow. Got a dude coming over to help me get the sub box downstairs too.
The voltage meter/ammeter lights up too. I didn't fry it KHA :)
Will just have to see if it's actually reading amperage once I get some music going. The voltage is accurate, measured with my DMM.

14.8V cold idle, fell to 14.6V warm idle. I'm good with that :)
She lives today. She breathes tomorrow.
So, ran into some issues. Leviathan took a dump :(
Good news is that [MENTION=142]Vertex Audio[/MENTION] is amazing, and gonna work with Zed and get the amp fixed with no costs to me. They are awesome, if you haven't checked them out, do it now.
Anyway, I found an old MTX 50Wx4 @ 4ohm amp, so my mids are very underpowered, but I have a front stage.
Here's a pic of the amp rack with the Zed still hooked up. I love it!

And the 5.0k wiring. It's so smexy!

Here's the temp amp in the battery box:

And a wider view of the clusterfuck of wiring. Can anyone see why I have engine whine????? Lmao!

Now, I don't know if it's just because I haven't had music in here for like a month, or if I just haven't been in loud vehicles, or it's just because it's mine, or what it is, but this is the loudest vehicle I've been in. Here are some vids:

Vids don't really show much, I did a decent job deadening I guess. It's much more impressive inside the vehicle.
Voltage is rock steady with only one additional G31. The ammeter does work [MENTION=8]keep_hope_alive[/MENTION]! But I think for some reason the scale is way off, seems as though a reading of 010 means one hundred. Not sure, I'll watch it more, but I don't think I seen a reading of over like 025, so that makes sense based on where my gains are and the size of the amp.
Right now, the PR's have no additional weight. Haven't found the tuning right now, haven't done any testing like that yet. Gain was also set by hand, so it's not tuned at all. This was day 1, it's only getting better from here :)
I'm not worrying about my front stage right now until the Zed gets back.
Got a box in the mail from [MENTION=33]PapaGeno21[/MENTION] today. Here's what was inside the box:

Didn't even have the decency to spell it out -_-
And inside that were these:

Gonna do these this weekend. Also gonna visit Lowe's and snag some washers for my PR's. Gonna tune it down, and actually set my gains.
Also sent out the Levi today.
So, first thing I did after work was tune this box down. Added 20 washers to each PR. Don't know the weight of each washer, but I know the count, so it's not super important right now.
http://i723.photobucket.com/albums/w...ps6f394e46.jpg
Did the cone resonance test again, and found my tuning to now be at 27Hz.
Next thing I did was set the gain on my 5.0k. Used a 50Hz -5dB tone. First I found what I was at, then I adjusted gain until I was at my target voltage of 65V, which is about 4200W RMS. Here's my findings:
Before adjusting gain:
A/C Voltage: 36V
Wattage: ~1300W
After adjusting gain:
A/C Voltage: 65V
Wattage: ~4200W
Yep, all those videos above (and what you heard [MENTION=115]FamousMassacre[/MENTION] and [MENTION=173]myjaja[/MENTION]) are with these two subs on 1300W, so roughly 650W to each sub. Tuning was at 35Hz.
This tuning is much better. I'm not missing notes down below, and I can hear the peak that was around 36-45 flatten out a little. Playing 27Hz at 4200W, my PR's are crying. Just screaming for mercy. These things are moving a LOT. Thinkin about tuning down just so I can have a little leeway in their movement. On the other hand, part of me just says fuck it, if they shred I'll have PSI build them better next time.
More to come, haven't played it barely at all. Need to find somewhere to go where I won't piss everyone off lol. But things are moving around on my vehicle much more now.
Got my buss bars installed this morning.

Kudos to [MENTION=33]PapaGeno21[/MENTION], he made these, and they were perfect, dropped right on to the terminals without me having to move the batteries at all. Wiring still isn't real clean, but better. Can't really do TOO much with that temp amp in there. I'll be doing cable management once the Levi gets back and I can get that MTX out of there.
Really the only thing left to do is figure out how I'm gonna cover the mids.
By the way this tuning is so much better for my tastes.
Finally vacuumed and cleaned the truck too. Gonna head down to the weekly car meet tonight, we'll see what happens.
So, retuned gain tonight. Went from ~4200W with a -5dB tone to ~3800W with a -3dB tone. Also bumped my tuning up from 27Hz to 30Hz. No more noise from the PR's, so that's good. I'll slowly tweak from here. I'm gonna keep power here for a little while until I know my subs will take it, then I might bump that up. Might go to ~4kW at the -3dB, but I'm gonna stick with the -3dB tone. Fronts will be set with a 0dB tone.
Not sure if it was the tuning raise or the power decrease that helped the problem. Tuning these things is a delicate balance. If I go too low, they're too heavy and it takes a lot to stop them. But if I tune too high, it sounds like poo (to me) and much more music hits tuning frequency, which is where the PR's are moving the most. And then factor in power, both in relation to the PR movement and the 3HP's handling, and I've got a lot to test.
I honestly can't really tell a huge musical difference from 27Hz tuning. I'll have to listen more.
Here are two videos I took today:

If someone knows wtf I can do to keep my hatch glass from rattling off, I'm all ears.
Aaaaalright, pretty big update. Finally got all my tools to test and tune, including this guy:
http://i723.photobucket.com/albums/w...psc3d737e8.jpg
So I scoped my HU first. Did all three pre-outs. Got some weird things on the high (tweeter) channel. It wasn't clipping, but above 52/62, I got distortion at the peaks of the waves. I can't figure out how to get pictures on the scope off of it yet, but it looked like this:
Attachment 6504
[MENTION=8]keep_hope_alive[/MENTION] can you help me interpret that?
But the mid channel never clipped or got distorted. The sub channel had no clipping at 60/62, but hard clipping at 61/62. I set all gains at 51/62 because of the distortion I was seeing on the tweeter channels.
So then I set my gains. EQ was flat, so I sent 110W to each mid, and 70W to each tweeter. I'm sending about 4500W at 0dB (which is about 2300W at -3dB) to the subs. Then I ran the auto T/A and EQ on the 80PRS. It does a couple things that you have to go back and look for, like sub LPF and mid HPF and slopes.
When you're looking at these RTA graphs, pay attention to the blue top lines. those are the peaks, and the results from the sweep. I took these pictures after the sweep was done, at volume 0, which is why the red bars are so low.
So, first I RTA'd the low end, ran a 20-250Hz sweep. Got this:
http://i723.photobucket.com/albums/w...psace79a93.jpg
Kinda don't know why I did that. I then ran a 2 minute 20-20kHz sweep. This is the result:
http://i723.photobucket.com/albums/w...ps273bc7e3.jpg
Determined that the sweep was way too fast for the mic/software to pick up on the lower end. So then I cleared the RTA, broke it down, and ran a 90 second 20-1500Hz sweep. Then I kept the results, and ran a 90 second 1000-20000Hz sweep. This gave me accurate results across the whole range, that look like this:
http://i723.photobucket.com/albums/w...ps65836410.jpg
I just need to cut at 1kHz and 2kHz, and I should be sounding pretty good. It already sounds great, and the cool thing is I can hear the peaks at 1k and 2k.
Here's a quick video:

Gonna clean the wires tomorrow.
Got the Levi back tonight. No pics, but it looks the same. This was written on the contact info page I sent with the amp:
http://i723.photobucket.com/albums/w...pse7123e65.jpg
Installed it, functionally it seems fine so far. Got my fingers crossed, because if I have to take this out again, it's getting replaced with a Zapco.
Got it tuned up a bit, had to run the auto-EQ twice because the first time was complete booger. Here's what I am getting on the RTA (and again, pay attention to the blue lines):
This was my first full-range sweep after the auto-EQ:
http://i723.photobucket.com/albums/w...psef5f9a83.jpg
Sub was too high, and there's a bunch of things to fix.
Then I did a 20-1500Hz sweep. Sub was too high, but ignore that for now. This first sweep was at 80Hz crossover point:
http://i723.photobucket.com/albums/w...ps9c251232.jpg
Compare that to the same sweep, same volume, only crossed at 63Hz this time:
http://i723.photobucket.com/albums/w...psbdca7bb8.jpg
Much smoother transition between the drivers. Looks like my sub falls off quick after around 65Hz or so. Gonna confirm this tomorrow and run a sweep with the sub running without a LPF. Either way, I like crossing at 63Hz right now. Smoother transition, my mids can handle it, and I can get a little more punch out of the subs before localization kicks in.
After about an hour of tuning and playing around, I am left with this today:
http://i723.photobucket.com/albums/w...ps194b19ad.jpg
Pretty sure I'm just gonna bump up the level on the tweeters one notch and see how that does.
One thing I did notice when setting gain with a 0dB track is that it started to clip around 36V on a bridged channel, which is around 160W at 8ohms, which is much less than what I should be getting. It's possible I was screwing something up, so I'm not blaming the amp, and it's really not even an issue right now as my mids are really moving set at around 110W, but it's something I want to test.
