bubinga08 Posted January 28, 2009 Report Posted January 28, 2009 I have a stock 80 amp alternator in my toyota corolla. I currently have 2600 watts rms going through 2 batteries. I was wondering when is it time for a high output alternator. It's over 9000!!!

(2)-RFT165s components, ...... 4 separate 1 inch tweetersRF T600-2(fronts) Punch 450.4(rear) Audiocontrol 3.1. DC power 260amp alternator w/MLA Module

Thanks man I should get a voltmeter. It's over 9000!!!
Guest KyleCannon Posted January 29, 2009 Report Posted January 29, 2009 Personally man, with an 80 amp alt, you need to upgrade regardless, your batteries probably never see full charges anymore. I was in that position, had an 80 amp alt with a D2400 Powermaster and when I came home, hooked it up to the intellicharger and it took 3 hours to charge. That was also after I got the 300 amp alt and drove home 60 miles, it was still that dead.....
Boon Posted January 29, 2009 Report Posted January 29, 2009 If your voltage drops below your alternator's normal loaded output (probably 14v or higher) then the alt isn't keeping up with the load. If it drops below ~12.8v then your alt and batts combined aren't keeping up with the load. 10.x volts fo' life!
