  1. I disagree, it doesn't work like that. For illustration and simplicity's sake, let's pretend your 5ks are seeing 1ohm each. We'll use DC Audio for example. A single 5.0k at 1 ohm can put out 5,000w. Lets assume at 5,000w it will pull a maximum of 500a (at 14.4v) from your electrical as evidenced by the fuse rating: 2 of them would pull 1000 amps. Using that logic, a 10k should pull the same amount of current at 0.5 ohm and therefore be fused lower than 1000a if rated at 1 ohm, but it isn't. It's rated at 1ohm and requires 1000a of fusing. The only time you'd see the situation that you're describing is if you were running 2 5ks strapped at .5ohm. Each would be seeing 0.25 ohm making them pull current comparable to a single 10k at 0.25. The only thing on the electrical (input) side of the amp that is effected by nominal impedance on the output side is efficiency of the amp, which wiring down could potentially make it draw more current if wired lower. Having the power to the amps wired in parallel has nothing to do with the load your amp is seeing. 2 5ks at 1 ohm each will pull the same as a 10k at 1 ohm (I'm generalizing for illustration purposes obviously). Hope this makes sense.
  2. I approve these updates!!!! So much JY Pwwwwwwrrrrr! Running 2 5ks at 0.5ohm each would be the equivalent of running a 10k at 0.5ohm, not 0.25. If you were running a pair of strapped 5.0ks at 0.5ohm then it would be like a 10k at 0.25ohm. Just for the record. Either way, your electrical is on point! Keep up the good work!
  3. Some more parts showed up for my charging system upgrade, going to attempt to get power steering worked in if I can! I'm really excited to tear into this pproject this winter! New serpentine conversion brackets, ps pump, mechman alternator bracket and xs power vcm Oh and the remote I ordered showed up, thought it had a volume knob but turns out it's just a d pad
  4. Thanks man. So I might have done a thing.... CES was running a hell of a sale on small case alts, so I ordered 4. Going to be a challenge to fit 6 under the hood of the truck, but I have a plan. Going to retrofit a serpentine setup from a tpi camaro on. Nearly 2000 amps of alternator should kick some ass! Have something kinda ridiculous up my sleeve I'm fairly excited to unveil, but I am holding off until I have more of the parts in hand. Muhahahaha.
  5. 2 coats down, 3 more to go...gotta order some satinizer so it wont be flat black. Going to do the cap and redo the front next week most likely. Got a new bumper on the way too.
  6. Not a lot to show off but a lot to tell in this update. I finally got around to lowering the tuning of the low tuned chamber. I took about 6 inches of width out of it which lowered the tuning to around 27hz instead of 30-31ish. This ended up nearly accomplishing the low end cutoff frequency I’m aiming for of 20hz. Right now I can play down to 22hz at full demo volume (about 3 clicks from full tilt). It will play lower but they really start to unload at 21hz and output drops off significantly. I also did a few more extended demo sessions and have gotten a good feel for the bandwidth with the new port tuning. It plays strong from about 22hz to 58hz. I’m guessing it will play a bit higher but my low pass is set to 63hz so that’s probably causing a roll off above 58hz. I’ll probably increase it for testing but in real world anything higher than 58 will probably cause thermal issues due to high power / low excursion. Also did a ton of very long demo sessions including 6hrs last Sunday at a meet, 4hrs of that was nearly straight with only a couple of 10 minute breaks to go get demos from other people’s builds. The shortest demos I gave that day were 3 minutes on a song that was nearly non-stop bass notes, and many of the demos I played significant portions of other songs back to back with it lol. Definitely got some major heat in the neos, by the end of the night I was playing a song with a nearly constant 22hz bass line and it was like I had the heat on in the cabin, you could feel the heat coming out of the high tuned chamber hahaha. Also did a couple 1hr demo sessions yesterday as well as some testing. The testing was a bit disappointing unfortunately. It seems that the truck doesn’t do very well on music at all. Power is super low on music but I want to do some further testing before I point all fingers at that. On a good note, it seems to be super efficient on low power and I managed to get a 149.5 on only 1367w driver window open at the dash…but the best part is, it was at 22hz! After the rather disappointing testing, my buddy and I decided to just listen to it instead. Since adjusting the ports it now plays door open as well as both windows open. My buddy decided to experiment and opened the passenger window and realized it’s a MUCH better demo experience both windows open than passenger sealed driver open. One of the most common observations I’ve heard regarding demos was that there was VERY little air movement on the passenger side. Luckily, my buddy said the decrease in SPL was almost un-noticeable yet it got 100 times windier which made it feel much more impressive. I’m pretty excited to demo both windows open now, an added bonus is it’s MUCH less stress on the doors! Hahaha. Anyway, I’m toying with the idea of trying a series tuned 6th with just the 2 woofers for shits and grins. I’m sure it will get louder and a lot windier compared to the current enclosure, but I doubt it will sound as good. So that might actually be the next thing I do, just gotta come up with a design I’m happy with.
  7. Good call, done! I'm glad to hear! Yeah, she was running a little hot because I forgot to top off the coolant after fixing a small leak lol. Small update inbound soon.
