What alternator are you getting? What is the amp rating?
Are you running anything aftermarket that has a high draw?
RIght belt? Too tight? Lined up correctly?
What is it that makes you think it is frying or what are the symptoms?

Is it frying as in burning the windings on the stator? If so you either have high resistance in the wire going from the alternator OR your truck is drawing more than the alternator is capable of putting out.

I tried a napa one this time and its only 1 month old and went on a 80km drive got back in and read like 8 vand had to get boost.
On way home after about 1/2 od driving the amps would hold at the lights but when I got home and started turning stuff on/off, you could see volts going up and down.
As far as too tight , how would I know? It is lined up correctly

Sounds to me like you're drawing too much for the factory alternator to handle. What's the wattage on the amp for your subs?

Oversize batteries don't mean jack if you can't charge them as fast as they're draining. All that does for you is give you a large reserve when the alt lets go.
2 500 watt amps would equate to a draw of ~82 amps all by themselves. Couple that with the rest of the electronics equipment in the truck and you're definitely pushing over what your alternator is capable of.
Depending on year and alternator. The trucks that had the 3G Alternator had 130 amp alternators, whereas the ones with the 6G style were 110 amps. Ford never offered a 165 amp alternator. They DID however offer a 140 amp for the ambulance packages. They also offered dual alternator for the ambulances as well.

as far as I know the factory alternator is 110AMP
with 2 500 watt amps you have the potental of drawing around 84 amps there alone...
If you regularly crank the **** to 11 then you are drawing close to 84 amps on the stereo alone, add in the IDM, fuel pump,exterior lighting, head unit etc and you are over the 110AMP alternator limit....
end result...I bet you need a bigger alternator
