Alternator Question

[UCF_Knight24 10+ year member]

I'm currently driving a 93 Ford Ranger. I believe the alternator is 95 amps. How much of a load can I run before I should consider getting a HO alternator and new battery?

are you asking about for stereo use? like how many wrms before needing an H.O.?

If you get the big 3 or already have it done then I would say push 1000 watts

if the question is about sub amps, then you can not just answer 1000watts. you must look at the amp's efficiency and then figure out what its power requirement will be.

Isn't it possible to run a lot of watts as long as u have good batteries?

You should definitely get a good upgraded battery first and foremost, no matter what wattage, even for a 100w amp.

my 95A stock ranger alt held up for about two years running over 3000 watts and charging two batteries. and over that time my voltage drop wasn't too bad considering... but obviously there was a lot of stress on it and eventually it died on my way home from work. i'd say if you're running over one thousand or more watts you should look for a HO alternator or carry a spare OEM because it will eventually burn up...

Roughly, I would agree that 1000RMS is the most you'd want to consider, and even then expect to upgrade the wire under your hood with the 'big three'. Worse case you'd have to get a good AGM battery under the hood.

You don't need to consider HO alt unless you plan on running 2000RMS +. You could probably get away with extra batteries in the trunk until then.

i was running about 1500 rms on my ranger for a while, i had some good voltage drop, but my alt is fine now.

I'm about to put in an Ohio alt though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I ran ~1100 in an '88 Ford with a 75A alt. Fairly demanding stock electrical system as well.

Unless you happen to be running the least efficient amps ever built I would expect 1000w to run w/o much trouble -- stock alt, stock batt, even stock wiring.

thanks for the input. now i'm going to decide on a new pair of subs =] i'll probably end up putting out around 1000 watts rms
