They can do well if you are burping (constant load), but playing music is a whole different matter. Playing music requires batteries. Period.//content.invisioncic.com/y282845/emoticons/word.gif.64b12e39f936af3b4fff38a1c0bd0244.gifIf you tried to put a 250A+ alt in that car, you would have only about 40 hp left to drive with. I am sure you notice how much power the AC takes from the motor, imagine that times 2 or 3.See my comment above. Just because an alt is rated at 250A does not mean it can output that at any given time. At lower RPMs, it will put out a fraction of that 250A. Also, if you have a variable load (music) then an alt cannot ramp up it's output fast enough to keep up with the demand. Batteries are still needed.I am not trying to advocate that an alt is not needed. I am saying that there is no one solution. When you are asking for 2000W+ power, you need a serious investment in power. You will need a strong HO alt plus extra battery capacity. The batteries you choose should be able to provide power quickly. That is where the car audio specific batteries come in. On top of that, you have to make sure that all of the wiring in the vehicle is large enough to handle the amount of current that will be surging through it. A 2000W system will be pushing ~ 140A of current alone. That would require at least 2 gauge wire just for the audio. Add in the rest of the cars needs and you are well above what a piece of 2 gauge can handle. You will need to do the big 3 with 1/0 for sure.</blockquote>
