I didn't say replace your battery; I said: Anyways, if you get yourself a decent main battery under the bonnet with a secondary (or even tertiary) battery in the boot, run some good 0 gauge cable (more than one would be even better) to the boot, and do the 'Big 3', you should be fine to run a few thousand watts RMS. If you really think that just simply leaving everything as it is and upgrading just your alternator is going to fix your problems, then you are going to have to find someone who can re-wind you current one (or a spare). There are currently no high output alternators that are sold as they are to bolt directly up to the 2GR-FE. Part of Big-3 is to change Alternator isn't? I have upgrade the Power cable to 0 gauge, replaced Factory Batt and Already installed a Secondary Batt, But it seems don't really last that long, especially Staying at 13.8V or above. Don't really understand why... That's why i am looking at replacing the Alternator now... to see if that can make it staying at 14.4v...

If your amps are going to need that much power, factoring in inefficiencies, I'd be guessing you're expecting to run about 2500-2750 RMS? Realistically, are you going to run at that power all the time? Think about it. Really all you need to do is get yourself a second battery installed to cover for when you do run it at full power but for most of the time when you do run it at normal listening/driving levels, the stock alternator will be able to cope. Well, ATM when i am listening to the music, the Headlight flashs when sub boom. don't even mention about the light bulb for door. they turns off and on, off and on. when i am listening to sub. And yes. i have already replaced the Factory Battary. This is why i am looking at getting a better output from Alternator... which i believe to be the last option.

first of all you don't buy a higher capacity alternator, you simply have your stock one respooled. this can take a 60amp alt up to about 100amp if required. this said unless you plan to run 10 amps your stock alt will work fine. if you kown anything about audio there are little things called capacitors which store power for peak usage of your subs that will work the trick under most circumstances. saves getting your stock alternator respooled. go here for an explanation and a price - http://jaycar.com.au/productView.asp?ID=RU6752&keywords=capacitor+car&form=KEYWORD Welcome to TOC! Yes, I know Capacitor, But Capacitor does not really Charge up and provide a Constain High-output. It helps but doesn't really do that much trick. Instead of Capacitor, Battary Do even better job. The reason of looking at getting a better High-output Alt is that it is the only way to produce a Continuese high-output instead of few second. My first Amp requires 80amp, Second Amp requires 180amp so that total at least 260amp (Continuesly), These are the links that example some techni. But simply i don't know what and where can i get for Aurion. http://www.aa1car.com/library/alternator_highoutput.htm http://www.alternatorparts.com/

Need some help to purcahse a High-Output Alternator for Aurion 2010. Does anyone know which brand model and how much it cost and where i can get them? Also does anyone know how is the output on Factory Alternator? I am running a very high output car audio, which may require an upgrade.
