Ive got a 96 xlt, 5.0 jw about how many amps my stock alternator is puttin out?
is this alt. efficiant enough to power a 2500 watt sub amp? ive gotg a heavy duty battery and im gonna upgrade my big three
my 94 xl sport always had 130 amp ones, apparently it depends on wether or not you have air conditioning, I do so I guess that's why.

2500 watts RMS would take some 180 amps if you are floating the battery at 14 volts. How much battery you need given the alternator output depends on the average power the amp typically delivers. If you have 2500 watts to catch the peaks without distortion, your average power may be half that. You can get a good idea of the real power the amp manufacturer expects to draw by what size power lugs are built into the amp. If they are not at least a #4, it isn't likely to really be 2500 watts.
how bout like 1800 watts at 14 volts, thats more realistic to the amplifiers i might choose
With any Direct Current supplied device, anything on a vehicle for instance, WATTS=VOLTS X AMPS
AMPS = WATTS / VOLTS and
VOLTS=WATTS / AMPS
Amplifier ratings are quite overblown as pointed out by Wagonized. Bigger numbers on the box leads to bigger sales. Some of the most efficient loudspeakers can deliver close to 100db sound levels with as little as 1 watt.
