Hey everyone, I was just plannin on putting a bigger audio system in the camry. My current alternator is starting to see the wear from the load that my current audio system is putting on it. I'd think the 3vz engine has the 80amp alternator. Anyone think that I should go bigger? If so how much bigger should I go? 100amp? 120amp? I current have a 1900watt amp, that's runs about 700watts rms. I plan on getting another 1900watt with 700rms. Any suggestions or anyone know of a similar thread? I tried searching but didn't get anything. Thanks.

performancecenter.com has some upgraded ones. But they are model specific. However they do have up to 180watt I think. Check it out. I posted about it a few weeks back.

Either that or you can get one off a 4Runner.

alternators quite expensive...esp. a new alt upwards of 150amps and up....
i assume u have upgraded your batt. to an optima yellow top or similar and upgraded big 3...i know that gen 3's (maybe only the 1MZ-FE) can directly transfer the Highlander's alt (which has both 100A and 130A alts.) which u could find at a junkyard...
