  1. That's my point, you disregard ACTUAL EXPERIENCE in favor of something on paper. We know one to one, OFC is better. Not once has that been debated. But when I used CCA I experienced no drop in performance electronically or spl.

    You simply cannot disregard ACTUAL events simply because on paper it couldn't be. Actually doing something is a part of science too, why are you so focused on what you read instead of what you do? I'm not saying use both, I'm saying wire properly using OFC. Then wire the exact same setup properly using CCA. What difference will you see? Ignore what you see on paper, do it and then see what actually happens.

    Devils Advocate. What if the power you lost did NOT result in a score difference? Is it possible that there is another factor in your car that limited your score to what it was?

  2. One thing I think would be interesting to test: OVER wire a car. Burp a score, measure voltage drop.

    With both OFC and CCA, test the minimum number of runs you need to maintain the same score. This might work better if someone had a bit more alt power. Something that can really strain some wire.

    TeamHT I was thinking that even though you swapped out OFC for CCA and kept the same score, what is the minimum amount of wire you could get away with? I think that would be a more valid test. Especially looking at this with a savings perspective

    You can easily do this with smaller wire. It is scalable. Test using a 500 watt amp with 4 gauge wiring. Not much of an electrical strain.

  3. OFC > CCA.

    When you see why you'll slap yourself.

    Edit: you guys are really gonna argue with an engineer that just reinvented an amplifier topology to build the T15K? Maybe you should humble yourselves because you sound as bad as the noobs on this site who know everything already.

    Not to be an ass, but the opinion pushed is being backed by REAL WORLD TESTING, not on paper. yes as a DIRECT comparison, OFC > CCA, but for current carrying capacity (not resistance), for the cost CCA is better. You can do 3 runs of CCA for the price of 1 Run of OFC. OFC will carry 300 max, CCA will carry close to 600.

    So are you willing to lose battery capacity in extra resistance? Cost isn't the only factor influencing the answer here.

    What extra resistance? The comparison is 3 runs of CCA vs 1 run of copper, based on the fact that you can buy 3 runs of CCA for the price of one copper run.

    But for simplicity, I will compare only two runs of aluminum to 1 run of copper. IIRC 2 wires identical in size run in parallel act as a cable 3 sizes lower. So those two runs equal one run of aluminum 4/0 in size. One run of aluminum 4/0 will yield less resistance than one run of copper 1/0 of the same distance.

  4. Blindly? No. Tony has proven himself.

    But its funny how it doesn't even seem to give some of you any pause...

    Then you are basing this off of faith. There is no doubt in my mind that Tony's grasp of audio knowledge surpasses almost everyone on this site. That being said, people want to know why so they can understand the answer.

    The answer is either OFC> CCA or CCA> Copper. Tony says OFC>CCA and while I don't think he is wrong, WHY is he right? What is classified as "better?" Same cross section, same weight? What? WHY is it not OK? It is not an argument, it is us asking for the proof that it is right.

    These claims are all pretty exciting and interesting and I hope to learn a bunch from watching the videos.

    No he gave us the answer, I just want to see the problem. I have the utmost respect for Tony and like reading his lessons :)

    However, this is a tease god dammit.

  6. There is a lot of misconception regarding CCA vs copper wiring. I don't think everyone is on the same page. I anxiously await some videos.

    One area of mention is making damn sure CCA connections are terminated correctly, because of the way aluminum expands and contracts due to heat differences. A lot of screws back out of terminals etc because of this. The wire is also more brittle. At the end of the day, steel frame is even less conductive than aluminum, however we see it acceptable to use as a safe path for ground? What is the difference here? Safety! The steel remains solid at temperatures where aluminum starts to expand and contract....But pound for pound does that remain consistent? After all, one pound of aluminum has almost twice the amount of current carrying capability of one pound of copper (i.e. 2 2 ft runs of CCA will carry more than 1 2ft run of copper at the same weight). Again, aluminum has a way higher chance of failure when introduced to heat and vibration. Proper termination is a must.
