[QUOTE="fatboytyler, post: 8349136, member: 658624"] To give you an idea I ran 300 watts to my door speakers annd 1200 to my subs on a stock 100 amp alternator (with Big 3) and a lead acid group 27 battery. Never had any issues. 150 Amps is pretty decent power. Take the advice everyone has already given you. Car dealerships are pretty much stupid. I called once asking where/if they could modify my ECU a bit for me and they told me that they couldn't because it would void the warranty... Its a 15 year old 247,000 mile vehicle... Big 3 upgrade won't harm your car. I noticed I got almost .5 volts of drop anytime I turned on my headlights, but after the Big 3 you couldn't even tell unless you had a nice voltmeter hooked up. You can't tell me that hurt my electrical. Just be careful because if it is anything like my mom's Rav4 (It might be a 2010 actually) it is kind of a pain to work on. [/QUOTE]
