amps and alternators

Is there a website that gives the amperage draw of most common model amplifiers and the amp rating of factory alternators.  I have a 1996 Ford Festiva and i dont know what the amp rating on the factory alt is, how can i find this out.  ThanksClarion DB36MP

you can figure pretty closely the amperage draw of any amp by using it's RMS power rating. Just check the ohm's law link on the left over there. Divide your wattage by your car's voltage(usually 14.4) this will give you the amperage draw of the amplifier using it's RMS power rating.Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

To find out what your alternator "will" put out, you can test that while in the car. My mind is completely blank at the moment, but most garages can do it. If my memory serves me right, it's a carbon composite capacitor and most have a variable load and will tell you at what point the diodes fail. So you just load the alternator (with car running of course) and increase the load until the diodes fail... At least that was the way I was taught... My 160amp in my Jeep that Nathan from www.excessiveamperage.com actually put out about 185amp before it dropped below "poor". (I'm extremely sick, sorry for the lack of details)
