So im thinking of upgrading the stock 90amp in my 93 xj sport. Im going to put a sound system in it and a LED bar on it. I was thinking of getting the Omix-ADA 120amp alternator. Im a just the new kid to haha. Would like to get feed back if this would be big enough to support the system and LED bar.

 

Have a local shop build you one.

I won't buy Omix anything.

 

how many watts are you adding?

you upgrading your cables?

 

how much would this run me? The Omix is like 200 buks :/

 

not really sure yet on the watt output but yes already have upgraded cables.

 

have you priced it against the 136a zj alternator?

 

yea but i need to grind things down and i would prefer not to you know.

 

why wont you buy Omix brand?

 

I bought a used 136 amp and had it rewound to 160 amps at a local shop. There is so little work required and simple to make it fit (took less than 20 min) and that was getting the tools out also.


Make sure you do have an upgraded wiring setup before installing a higher amp alt. Look in the fore sale section here or PM XJWONDERS for a set he sells.

 

it wasnt difficult...i put a 220A in...just grinding with a dremel...didnt have angle grinder at the time

but yeah theres different solutions to your situation

 

I did once..............junk.

 

You're doing it wrong. Cart before horse.


You find out the intended load, then you size your cables and alternator.

What you did is like buying a dump truck, then figuring out how much gravel you need to carry.


What did you do for the cables?

 

Your an electrician, right? Any second now I can see you whipping out Ohm's Law!

 

V = I x R

It's not just a suggestion - it's The Law!

 

Who's law? ;-)
