2 amps

Yeah I agree with you I see what you mean. Iapologize if Iseemed to come off with an attitude that wasnt my intention at all. You brought up a good point that needed to be brought up. If you dont have the power to begine with then your going to work the alt harder than it already is being overworked which is more of a headache than it is worth

exactly how high an output do i need for my alternator? my ride is a Toyota Hilux 2005 model. Can i see my current alternator's output in my manual?

Get the biggest alternator you can afford.  It allows for future upgrades and puts less of a strain on it.That's my opinion. Take it, leave it, or correct me.

When you buy an alt make sure you get one from a company with a good reputation like Stinger or Ohio Generator or something along those lines. There are other companies that have a good reputaion that sell them ask around. I only bring this up because if you buy a cheap no name alt you could end up frying sensors on your vehicle.So research before you buy please. Sensors are very costly I work on cars daily and Isee these outragous prices and Id hate to see you have to go through that if you don't have to.Just do yourself and your bank account a favor and research really well don't be too quick to buy or try and get a cheap one it could cost more than its worth so please be carful.

how do i know if my alt isnt big enough?
