[QUOTE="HardofWhoring, post: 8863754, member: 674149"] if you take 3000w divide by amp efficiency which is 88%. 3000 / .88 = 3409w. That is your amp draw. Then divide that by voltage, 12v when off, 14.4 (used to be standard) when running. 3409 / 14.4 = 236 amps. That's the amperage draw at full volume maxed out, when you are setup to run 3,000w. If you go 4,000w / 14.4v =277.7 amps. Then you need to add on to what your vehicle does. Generally your stock alt is going to do everything it can maxed out: EFI, ECU, electric fans, low beams, high beams, brake lights, AC, interior lights, (stock) radio, cig lighter, dash lights, and have a little bit of head room. Your amp doesn't constantly draw 277 amps even when you have it full volume, just when the heavy bass hits. Between that it's recharging, so it's relative to what music you listen to. Rock and country have more time between to recharge. Rap and generated bass music has a little. With 277 amps, I would say the range is about 200 -250, and you would never have a drop in voltage. With your vehicle and you live somewhere cool enough that you don't use the AC, or hot enough where you use the electric fans, then you're never going to need 2/3rd of what your stock alt can do. IMO, an alt is something you DO NOT want to buy twice, because you are going to upgrade to 12% more. A good one is a decent chunk of money for your system. With your amp being capable of 5K watts, and if you EVER MIGHT want to upgrade subs to that amount, I would go bigger now. I honestly wouldn't expect to find too many options for a 2000 Camry though. If you can find 250-300 you should be good. Also know that when you do go shopping for an alt, there are two numbers that matter. Amperage output at or near idle, (what will it do when you're at a stoplight), & RPM needed for max output. (What will it put out at cruising speed). A 300amp ebay alt is going to do less at idle than your stock ~100 amp alt, and won't do full output until over 3K rpm. Well where do you cruise at? Will you ever even see that output? A high quality alt will do most at idle, and full output around 2K rpm. Think about how you drive, and where you listen to it, and know what RPM you cruise at, or are usually driving at. Get those two numbers before you buy, and if they won't or can't give them to you, then keep shopping. That's going to be the difference between a $200 alt, and a $600 alt. [/QUOTE]
