  1. CE AUTO ELECTRIC SUPPLY CABLE Meets or exceeds full AWG (American Wire Gauge) specifications. Is made of Pure OFC (Oxygen Free Copper) and tinned for corrosion resistance. Has a soft, flexible 600V PVC oil resistant jacket. Is dry rated for between -40 to 105 deg C, wet rated for up to 75 deg C. Is BC-5W2 Marine Compliant. Yep. Be sure you're comparing apples to apples when shopping for cable sir. Just the tinning adds 8% to the raw material cost.
  2. Like FREE stuff? Well then you definitely want to get in on our FREE T-Shirt or Hoodie Program! Each are SUPER NICE Gildan products with low shrinkage factor ( ! ), beautifully done artwork, and super comfy! Here's the skinny - https://ceautoelectricsupply.com/free-t-shirt-offer/
  3. SS is our oldest SMD Partner - dating all the way back to June of 2009 (wow!) . In that time, they've run some killer promotions and sales for SMD Members. This is the deepest one I can recall!
  4. Still got it but it's likely going up for sale soon . . . Since the last post, I've put maybe 8k on the clock.
  5. What you didn't tell us is what kind of vehicle this is. Many, and I mean many, late model vehicles have all kinds of challenges facing you in the digital domain that must be undone or normalized before installing new gear - equalization contours designed to make $3 speakers sound like $30 ones, fully active systems with each component having a narrow bandwidth of operation and / or delay, multiple position contours overlaid on top one another, etc. In addition, you could have some impedance mis-matching with your interface which could cause frequency response irregularities, etc. So, share a bit more.
  6. And now . . . it's in full color! Check out this example I did for a positive battery cable assy for a builder that prefers to use all black cable. The red battery boot keeps things sane when it comes time to break out the booster cables. The smaller 8 AWG auxiliary cable goes to the under hood power center. https://ceautoelectricsupply.com/custom-cable-builder/ If you've not tried it by now, then check it out. Design a cable, take a screen shot of it, post it up here, and tell us what it's for. You can literally do this in minutes!
  7. Ready. Willing. Able. We build the very best cables in the industry, bar none. I'll stake my reputation on it.
  8. Check this out! Our CCB allows you to custom design cables to your exact specifications. AND, you can see the cable you've created before your very eyes as you're creating it! You simply have to try it - it's super simple on your PC or phone! https://ceautoelectricsupply.com/custom-cable-builder/ Try it out and let me know what you think!
  9. I like it. While SD's post is lengthy, it's also accurate. When it comes to charging system design, here are the factors you must consider: 1 - Intended use of the amplifiers - music / SPL / both 2 - Duty Cycle of the media (a function of #1) - heavily compressed pop music (or rap / bass discs) has a duty cycle of 50%, sine waves have a duty cycle of 100% 3 - Voltage available 4 - Current required 5 - Voltage Drop you're willing to live with (SD uses 5%, I tend to like 3%) 6 - Law of Diminishing Returns Once you have these answers, then it's a simple process of using Ohm's Law to arrive at the answer to a question like this. #6 is an ass kicker for sure. For example, you add three additional runs of cable and pick up .2dB on the meter. That's not insignificant if you compete - could make the difference between winning and losing - but the human ear can't detect the delta. Then, you add three more runs and pick up another .15dB on the meter. That's a total of 6 runs to pick up a third of a dB. Again, maybe that's what it takes to win. But, where do you stop? Personally, I don't think 90% of the members here at SMD are die-hard SPL competitors. Keep in mind when we're talking about thousands of Amperes of current and minimizing voltage drop, every single thing matters. Are you using the best materials available to you? Are your terminations done in such a way that voltage drop has been minimized. Etc. This process is referred to as minimizing your losses and it's what all of the world's best designers and engineers utilize. SD - well done. PM me your stuff so I can mail you the TORK2.
  10. Really, it's all about current over distance and how that affects voltage drop. Maybe I should build a calculator for such on our web site . . . hmmm . . .
  11. SD - I'd like this answer a LOT more if you edited it to incorporate the duty cycle of music. [Yes . . . I see what you did with the 15kw calculations - but let's get the enthusiast there more directly.] Let's all stay tuned and give SD the chance to edit accordingly.
  12. Lately, I've seen lots of video and photos of 10, 20, and 30,000 "watt" builds. While 30 runs of "oversized" 1/0 AWG power and ground cables may look the part, it's absolutely not necessary. First and foremost, the Laws of Physics are in fact Laws, not just really good ideas. They work in your favor as well as against it. Let's say that we design a system capable of 30,000 Watts RMS. As in - they system is cable of delivering 30kW of unclipped power to our speakers. The source of power is infinite (no matter how much juice we need, it can maintain 13.8 Volts - wouldn't that be nice?) Show me: 1 - the math on determining just how much current it would require to play music at 30kW 2 - the math to determine how many runs of 1/0 AWG copper cable it would require with the source of power located 15 foot away If you don't know how to answer, then your time will be far better served by learning how than comparing prices on cable for your next build. First person to get both right gets a FREE TORK-2 shipped to your front door (US only). This isn't designed to be a freebie. You'll have to earn it.
  13. Here's another video that shows the actual temperature difference between CCA and OFC. Real results from an industry icon that knows what he's talking about. Or, you can put your head in the sand and go along with the above response . . .
  14. So, your fuse block melts which causes the jacket on your cable to become deformed from the heat and that's somehow the fault of the jacket construction? If I buy a tire and it fails and shreds the quarter panel as it comes apart, I'm not going to repaint the car with the same paint as it all came off in the process. Come on man.
  15. Yesterday, Steve posted a video about the real differences between CCA and OFC. This has been debated for as long as CCA has been around. This got me thinking . . . Do you know why CCA was brought to market? Simple - as copper prices increased CCA offered a less expensive alternative. You want 1/0 AWG cable but can't afford it? No problem - you too can have 1/0 AWG cable. Now, let's think about that for a second and let this sink in . . . Sunk in? Not yet . . well keep thinking . . . OK. Now, my problem with CCA has always been how it's marketed. It's been marketed as a less expensive alternative. You sir - you don't need copper cable, CCA will be just fine for you. You, over there - CCA will be just fine in your build. The fact of the matter is that CCA has never been an acceptable alternative to copper cable, just an alternative. Had CCA been marketed truthfully, it would have been something like this - Pay Less for Less! Of course then, nobody would have purchased it. What I simply cannot wrap my mind around is how many have come to the defense of a product that was brought to market to deceive the ill-informed consumer. Thread after thread. Discussion after discussion. Amazing. So much so, that I gave up discussing it years ago. Want to run CCA in your build? Go for it. No matter how you rationalize the decision, you're actively doing two things: 1 - encouraging deception in marketing 2 - devaluing quality copper cable - after all, if you didn't need it neither does your buddy This is exactly what happened to the capacitor business. Quality products in plain wrappers in plain white boxes gave way to a turd cylinder with a fancy wrapper and a volt meter in a velvet lined box. Absolute shit. Marketing deception at it's finest. A quality product that served a real purpose was displaced by garbage who's only purpose was to separate you from your money. A decade of that made it next to impossible to sell a quality product. There are volumes to be learned here. As the owner of CE Auto Electric Supply, I've been approached numerous times by various manufacturers trying to sell us alternatives - but it's cheaper and you can sell it for the same money! Well, it's also not as good so that would be deception - we ain't interested. We're not interested in paying less for less. But, we often pay more for more. That's why we buy Snap-On tools vs Harbor Freight. That's why we buy Fluke meters versus some pretty import knock off. And that's why when I turn the system on in my Mustang, I just enjoy the music. You rarely save money when saving money. Next time someone tells you that CCA is just fine for them, help to educate them. Oh, and if you haven't seen the video here it is:
  16. We're proud to finally offer this incredibly compact and versatile PDC for high current accessories. For more info, full specifications, and to purchase a kit: https://ceautoelectricsupply.com/…/gep-dual-70a-relay-wate…/ This is my new favorite PDC - I can't wait to see what kinds of cool projects they're used for! Also, PDCs of this size can be interlocked (see last photo) for large projects - how freakin' cool is that?
