  1. Many modern vehicles manage the charging system far differently than what has been traditional. Specifically, the goal is to minimize the load the alternator places on the engine in an effort to improve fuel economy. A quick google search on your Infiniti leads me to believe it is one such vehicle. Typically, the ECU manages the output of the alternator via a feedback loop to determine the actual charge state of the battery. The ECU can even disable the alternator if it deems its not necessary - a function of monitored vehicle conditions such as mph, rpm, and charge state. I co
  2. If I were a betting man, I'd say these systems are crazy loud! Those door panels are insane. Great to have Audio Legion as part of the SMD Family!
  3. 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.
  4. 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/
  5. Interestingly enough, this topic seems to be quite mis-understood. Folks assume that more voltage is better; but, that is not always the case. For example, let's say that you invest a bunch of money in batteries and then you ramp up voltage to 15V or so. While your amps (with unregulated power supplies) may indeed make more output power (say 10%), the life of your batteries will be dramatically shortened from continually being overcharged. While 10% more power may show up on the meter, you certainly can't hear the difference. So, the pro of the extra power doesn't outweigh the
  6. 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!
  7. Still got it but it's likely going up for sale soon . . . Since the last post, I've put maybe 8k on the clock.
  8. 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, s
  9. 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!
  10. Ready. Willing. Able. We build the very best cables in the industry, bar none. I'll stake my reputation on it.
  11. 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!
  12. 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 pr
