Is it possible for a small 300 watt class D amp powering 1 12" sub to cause the alternator to fry, when everything is wired properly? I really don't believe it can, but i need to clear my name.

 

depends on the car.
what do you drive and no it shouldnt, my alt died on my buick with no stereo.
parts do wear out.

and the buick was a 97 with 250+ thousands km's on it

 

its a 94 saturn SW, i never even have it that load, plus the battery was just replaced, after getting stranded 5 times, so i think that may have put some wear on the alt. personnaly ive never heard of a small amp making the alt go caput. ignorance angers me.

 

if your lights didnt dim it shouldnt have been hard on your alt at all.

how many km's are on the car?

 

about 165K, and yah thats another point, with tthe setup i got i get absolutly no dimming, so how can I be putting strain on the alt if im getting plenty of adecuate charge.

 

HAHA! this is hillarious, when my dad changed the oil he didnt put the frickin cap back on so im guessing oil got on the crank and alt belt, wich will cause it to slip, and with oil on the belt I doubt you would be able to hear it slipping. but i bet youd see smoke.

 

yeah, that could do it. it does take a fair amount of power to turn over an alt, like 20-40 hp.

 

in my durango at about 140k km my alt starded to die i was seen 13.5 when it was 14.4 at 120k km .so 20k km yes i can see it dieing over time

 

on my 92 cavalier i was on my 3rd alt when i sold it at 255km.
on my 97 cavalier i was on my 3rd alt when i sold it at 368km.

yup, they wear out.
