Odyssey 925 and Alternator enough?

I am going to run 6 55watt halogen lights, no stereo but maybe a GPS. Will the 925 and the alternator be enough power to run this set up?
I run through the woods and brush and don't want to clean off some expensive hid's that's why the halogens plus I already have them. I have read all the posts and am somewhat confused by what I might need. I appreciate your patience and your help!

The rzr has a 500w stator but you have to be careful in how much you load it at one time as it can be easy to go over that capacity when you turn all your accessories on at one time.

The rzr is a 12v system, you need to be concerned with Amps and watts. To get watts multiple volts x amps = watts (ex:12v x 10a = 120 watts). With 6 55watt lights you are at 330 watts right off the bat if you turn them all on at once,thats not counting any other draw on your system(brake lights,etc). Once you exceed the capability of the stator you are draining the battery.

With a O925 and an alternator installed, you should have no problem running 6ea 55 watt halogen lights and a few other things at the same time.

A good article on this topic can be found on page 18 of the feb Side x side magazine HERE

I ran into this same problem on my old Toyota truck.

I put 2, 130w KC lights on the front. The math tells us that ...

130w
------ = 10.83 amps x 2 lights = 21.66 amps
12v

So a 30 Amp relay should work, with 8.34 amps extra capacity. Right?
Not exactly. Quartz lamps do a weird thing. They "act" as a dead short until they come up to temperature. The Filament conducts power easier cold, than when its hot.
I kept going through relays. It would fry them after a few times turned on and off. The fix was a 30 amp relay for each light and 100 watt lamps.

Some light kits come with small 20 to 16 gauge wire. Why?
Because it acts as a resistor, slowing the flow of power, until the lamps come up to temperature. You will notice the the wire gets warm. That's current being changed to heat.

You will need to add up all the lights wattage, plus what ever the ECU and all the other electronics,winch, gps, ect., need. 500 watts isn't going to go far.
Don't over work your stator. My guess is that it'll be expensive to replace. I wouldn't go over 50% of the maximum rating. This will save batteries too.
All of this is why LED and HID lights make so much sense.
Lots-O-Light, with little power.
And you know if something is going to fail, count on it being in a rain storm at night.
