Just got my Diamondboxx. Muhahaha

He bought some RE XXX tweeters from me a couple weeks ago. http://www.stevemeadedesigns.com/board/topic/201836-fs-bravox-exs6-mids-and-re-xxx-tweeters/ He paid immediately and informed me when they were received. A+ would do business with again. Thanks!

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.

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.

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.

Some head units let you choose different crossover slopes as well as points. On an amp you need to do a little extra work to know exactly where your filter is set at, since they aren't calibrated to the printing of the numbers on the amp case. Some people prefer a steeper slope and some prefer a flatter slope.
