  1. The Orion 8k has started doing some odd things. Sometimes, it won't output audio, and whenever it does, it makes a weird ticking noise. This only started happening when the weather got colder. I may end up sending it back to Orion for warranty work. I'm hoping it can work for the last couple of shows this year, but we'll see.
  2. Tuned in. I built a 55+ C pillar wall for 6 15s in one of those. They get loud.
  3. Thanks! I used WinISD to calculate port lengths and port velocity. All the math was pen, paper, a calculator, and drawing everything in Sketchup.
  4. Sooooo, Slamfest was fucking crazy. Here's a full account of all the shiz that happened. 2 nights before, the cone on one of my subs completely delaminated and exploded everywhere. That was cool. Suddenly, I had to figure out a replacement sub or a set of subs with 2 days before the show. Luckily, my team helped out and supplied me with a set of Skar VXF 12s (since they're local to Tampa) and we threw them in at midnight on Friday after I drove 14 hours to get there. Surprisingly, the VXFs did great; I actually gained .2dB door open on the dash. I suspect this is because the Crossfires are old and tired. About halfway through the day, my HU started shutting down the audio to the doors and displaying a message that said, "Output failure." After some research and trying everything I could do to fix it, the consensus was that the HU had shit the bed completely. I picked up a new Kenwood unit from Best Buy after the show and went to install it that night. I extended the HU harness for a handheld setup so I didn't kill another head unit from vibration/heat in the dash. Unfortunately, the new HU was bad out of the box (internal short - kept popping fuses). It took me several hours of fucking with it to determine that, as I assumed the issue was with my wiring. The next morning, my Teammate Lenry let me borrow his HU. I redid the connections for the harness and got it all working. We went to the show and I entered in ISPLL All Around SPL and Real SPL in the Wall 2 class. I ended up with a 155.7dB average for All Around at 36hz and 153.3dB average for Real SPL (Average of 28hz, 38hz, 48hz sealed on the glass). These were good for 1st place in All Around, 2nd in Real SPL (beat by .2dB ). Voltage wasn't the best, as it was hot as shit and the alt wasn't putting out what it usually does in decent weather. All around, it was a crazy good time hanging with everyone, giving demos, and competing. I'm honestly impressed as shit with these Skars for the money. Huge shoutout to my teammates who helped me make it down and stay in the competition. Diztruktion ftw!
  5. Still gaining tenths with playing with the front port. New legal peak is a 155.25 at 27hz, and it's now doing 158s door open on the dash in the mid 30s. 158.5s in the kick. The most notable difference is that voltage is up a bit (holding 13v on burps) and I'm now clamping 9200+ watts out of the Orion.
  6. Alrighty. I got the box work done (extra roof layer and steel brace) and shrank the front port 100 square inches. It's now doing 155dB legal at 28hz, 155.5 legal at 55hz, and 158.4dB outlaw at 35hz. I still have a ton of testing left to do in the next few days before Slamfest.
  7. I have the new mids and highs installed and one door completely treated. I may take tonight to try and get the extra layer on the roof of the box and mess with the bracing some. I got some 1" steel pipe with flanges for vertical and horizontal bracing. My buddy Brian is going to let me borrow his meter this weekend, and I'm gonna play with shrinking the front port a little and see if it gains. Fingers are crossed.
  8. Thanks for the feedback, dudes! I think I'm gonna pull the subs and ports and do some more box work in prep for Slamfest. I think I'm going to add another layer to the roof of the box (that's the thinnest, most resonant part at 2 layers) and add some 3/4" all-thread front to back, side to side, and top to bottom. That'll let me really cinch this thing down from every axis and tighten it up some more. I'm also going to build some port blocks to play with front tuning and see if I gain at all. I bet I will. This will also give me a chance to do some more filling/sanding/painting to make the box a little prettier. I ordered my new mids and highs yesterday (PRV 6.5s and tweets) and I'll be installing those and deadening the fuck out of the doors soon. I really want to see if I can pull 2.1dB out of this thing somewhere; I really want that 160 outlaw. I'll take pics and keep you guys posted!
  9. Thanks, DiBo! I'm actually running a CES 280a. They started making a new mounting system for a larger alt. New scores with proper voltage are: 154.8dB legal at 28hz 155.6dB legal at 56hz 157.3dB door open on the dash at 35hz 157.9dB door open in the kick at 35hz It does 157+ on music with the meter on the dash and door open anywhere between 30-40hz. I played Top Chef by Akon (Decaf version - 28hz) with the driver window down and it metered at a 156.6. That was after demoing for about 30 minutes. I'm sure it would gain a couple tenths with a fresh charge.
  10. I'm currently trying out one of Veach's 30ah banks. I'm highly impressed thus far. I have an Orion HCCA 8k at .5, clamping 7300 watts at 1.3 ohm reactive, and I'm only dropping to 13v.
  11. Alrighty. So, the Winston 90ah that I originally got for this build had some issues and was basically dead. It wasn't anyone's fault. It was just used and tired. Basically, after playing this setup on it for a week or so, it was dropping looooow. Like, 8.5v low. My voltmeter for up front hasn't arrived yet, so I couldn't monitor voltage. I went back and clamped the amp and measured voltage and it scared the bejesus out of me haha. That 4.5k clamped I was mentioning up there ^^^ was dropping to about 9v lol. Josh and I worked out a deal and he shipped me one of his Veachium 30ah to try out since the Winston was fucked. I got it hooked up 2 nights ago and gave it a run (straight out of the shipping box, no charging) and it was sitting around 13v full tilt before it nuked my 2 400a fuses haha. So, larger fuses are on the way, and this batt is nuts. I clamped the 8k again before it destroyed the fuses again, and it clamped 7332 watts rms rising to 1.3 ohm. 28hz, sealed on the dash. I should be able to get a lot more testing done this weekend. Stay tuned for new meter numbers and more reviewing of the Veachium!
  12. Here's a graph of the first testing sesh on about 4.5k clamped. Pretty decent response, I must say. I know it's not on the graph, but it does 154.0 dB at 28hz legal, and 154.2dB at 56hz legal. The peaks are exactly at tuning. We tested 2 songs and the results were: White Girl (Decaf Version) - 154.4dB at 30hz, 152.7dB at 50hz Paper Chasin' (DJ JD version) - 153.2dB at 27hz, 155.1dB at 34hz I need to do a full impedance sweep and make a corresponding graph, but at its low peak (28hz) it rises from .5 to 1.2 ohms (sealed up). I had to do this to keep the USB from flying out: I'll upload some demo vids to Youtube and get them on here asap. Stay tuned!
  13. Thanks, bud! Currently sorting out some really obnoxious electrical issues. Fun fact: It's doing 155s on music on 4.5kish clamped watts because of how bad voltage drop is.
  14. It's been too long since I updated this. Here's the pics of the finished wall with subs loaded. Many pics/vids to come.
  15. I haven't updated this in a while, so here's the last couple weeks of progress. If all goes according to plan, I'll have it playing tonight! Got a layer of 1/2" MDF on the back wall for paintability and added 2" standoffs for the amp. 1st coat of paint: Two more coats in: Sanded down all the bondo on the front of the wall: Threw together a quick little bracket and mounted the battery: Amp mount teaser: Vertical brace test fit: Some tasty crimps: Running a mess of welding wire: Yes, I'll be getting new batt terminals. Also, I still need to finish up the big three. SPL Cartel knob, NVX RCAs, and a little wire loom/heatshrink action: The amp is all wired up: Still have to connect the main runs to the batt. And the wall is all painted up and ready for subs! Tonight, I'll load the subs, wire them up, finish the big three, lay a couple of pieces of deadener on the floor, put the carpet and seats back in, and let this thing rip!
