1 ohm amplifier

OK so you guys are saying that when the lower the resistance the greater the current draw from the vehicle and it's basically imparative that the electrical system of the vehicle be upgraded. So running at 1 ohm will almost definitely (considering i want to run at over 1000 W power) have to change my alternator and 3 wires (big 3). This is important to me cause i like to pre-plan my sytem thoroughly before i invest in it. Thanks again i've been learning so much from you guys. THANKS!Prodigal Son

Well, yes and no.... You look at the amplifier specs, and whatever load you are putting on the amplifier, the specs will tell you the amp will make this much power @ that load. That is the important number, NOT what the amp is loaded with. You take THAT number, then determine how much currrent the amplifier will pull from the car... This means you need to decide FIRST which woofers you are planning on using, and then, WHAT load you can produce from those woofers to present to the amplifier. So, yes, if you are running 1000 watts, then you need to figure approximately 100A for a Class D amplfier, and approximately 115A for a Class A/B amplifier.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Prodigal: There's been some ammusing back and forth in this thread. For a good place to -start- learning more, check out http://www.bcae1.com/ It helped me tremendously when I came here to hang out with people that really know what they're talking about, like haemphyst. Good luck with your system. I would personally never consider running a 1-ohm load unless you're dying to compete, but I also listen to old folks music most of the time. New Project: 2003 Pathfinder
