FYI i think its just a type on the VAS. probably 34 liters on the VAS. not trying to to clutter up your build log. looks great so far!
I completely understand. Luckily we have the room to add at least 4 runs if we start to see issues. Running them post tests will not be difficult. I know the conductivity is less than copper, but I haven't seen any definitive numbers on how much amperage the frame will tap out at. Heard 800-900a, which would be an issue with us running 1000-1100a. We honestly won't know until we power it up. We have plenty of cable and space to run some front-to-back grounds if needed.I meant solid runs of wire from the alts to the rear. Not anything through the frame.
You're trying to pass 1000+ amps through a frame rail. Copper is 10x more conductive than carbon steel. Realistically you would need 10x more surface area of steel than copper.
Figure that a run of 1/0 is good for 300 amps at that distance. You need at least 4 runs of 1/0 copper wire to carry the amperage you have on tap. That means you need at least 40 runs of steel to do a comparable job. FORTY. Picture 40 runs of 1/0 together and you get the picture.
Steel is not good for conductivity.
Just my opinion, but you should do solid runs of wire from front to back.
Take a look at any big SPL build and you'll see dedicated runs of negative wire, especially on vehicles with multiple alternators.
Not trying to knock your build because it's impressive, but I'd hate for you to have voltage problems because you overkilled on positive runs without doing any negative runs.
I'll have to talk with those Russians hahaFYI i think its just a type on the VAS. probably 34 liters on the VAS. not trying to to clutter up your build log. looks great so far!
Thanks, man -- we're happy with how it's coming together so far.I never did the testing but a long time ago I read the frame is at best equivalent to 4 1/0 runs
Build looks awesome so far
Makes me want to redo my blazer
Sounds like a reasonable way to go about it.I completely understand. Luckily we have the room to add at least 4 runs if we start to see issues. Running them post tests will not be difficult.

Absolutely, man! By no means do I know everything. This is the first time the crew and I have had the opportunity to chase a 160dB. It's no easy task, and when dealing with this much power it's imperative to get everything wired correctly. I am totally on board with what you're saying if we start to suffer from voltage issues. Luckily, we over-ordered on basically everything electrical related. Honestly, thanks for your input -- it gets the wheels in the head to turn and start thinking.Sounds like a reasonable way to go about it.
Thanks for taking my input seriously and not just saying "whatever bro we know what we're doing" or something along those lines.
Good luck with the rest of the build and let us know the results!
Thanks man!! We can't wait either!Very impressed so far! I cant wait to see what it will do when you get everything finished. And a 152 at 25hz is epic!
I really doubt it can play that high. Fs of 29, Box tune of 30. It'll dig anything down low, but that high might be difficult for this setup.just curious how does at do around 60hz or is it really peaky down low? not a bad score. im going to make a prediction. 163.6.
