Default HO alt.

ive been looking for a while and cant find any threads on high output alternators.

what is the stock amps for a 06 ranger.

and how many would i need for the roughly 1500 watts im pushing

i read something about a 10% rule

like 1500 watts uses 150 watts (not literally, but its a safe guess to give some flexibility)

is there any truth to that "rule"?

the big 3 ground upgrade helps, but i believe the explorer (v8 or maybe even 4.0) alts are higher output than rangers and bolt up.

I heard a older model expo puts out a 130 amp alt and bolts right up

The Expo and Ranger alts(if V6) are both 130A rated. Most do about 180A.

And get a capacitor, they help.

X2 on capacitor, and deep cycle battery also will help your power levels stay constant during heavy loads.

dont get a cap. spend the money on a HO alt and do the big three. A cap only adds stress on the electrical system. a HO alt will do more help then the cap

My stock alt. was a 90amp. I upgraded to a 150amp HO alt and it has help a lot. Looking into getting an optima yellow top battery or adding a second battery now

Explain to me how a capacitor will "add stress".

A capacitor holds a constant charge and discharges to a specific load fluidly. How is this "more stressful" than the battery taking an overload directly (While powering all the things that make the truck run) and sending fluctuating amounts of power to all the loads that are connected to it, then getting a giant shock to replenish what is taken away?

Default Re: HO alt.

caps have a small reserve of electricity. Dont get me wrong they can work great IF you have the electrical system to support them, which most people who are considering buying them dont. When the bass hits hard and starts to draw from the cap, it drains fast, then starts pulling off the battery again. Now the alt is working to recharge the cap and battery. The best bet would be a deep cycle battery and an HO alternator along with big 3 wiring. If the alt cant keep up with charging the battery, it certainly wont help charging a battery and a capacitor.
Caps could help if the alternator is strong enough to keep the cap fully charged, it will help level out peaks and troughs in voltage spikes. It is not a fix for electrical problems.

This is what i have come to understand about the cap arguement. please if you have anything to add or correct please do

edit:
and to answer OP question you have between 95-130a alternator depending on the engine.
and the amp will pull about 105a @14.4v and 125a @12v
Watts/voltage=amperage 1500/14.4=~105a

from my experience caps dont do a god damn thing, I've run with and without and still get the same exact drain

If your capacitor is drained that quickly it is underrated for the power draw the load is generating. The draws that are severe enough to drain the capacitor are the exact reason to have the capacitor in the first place though, it is there to protect the load(amp) and the battery from wild fluctuations in current and the relativistic drastic power surges that come with the current change.

Simply put, it's like you have a 5 gallon bucket of water, and your trying to fill a 2 liter coke bottle. The capacitor is the funnel.

You should be designing your system to not need a capacitor in the first place. They CAN work but most people's installation of them is a joke.

1500 watts is 125 amps at full power. As for how many watts it actually uses on the input vs output vs loss, god only knows. However you can be pretty confident that your stock alternator won't cut it.

You need at least 50-60 amps set aside to run the truck. That leaves you 30 amps for accessories on your stock 90 amp alternator. And furthermore, no alternator can generate it's rated capacity at idle. Figure on losing at least 10-15 amps at idle. I highly suggest overdrive pulleys for that alternator.

So you'll be needing at least a 150 amp alternator to power the truck and your sound system. The alternator should be capable of supplying the full load at all times while the engine is running. You'll also need to upgrade the primary power wire from the alternator to the power distro box under the hood. Your battery is irrelevant and not used if you've done it right. The battery is for when the engine is not running. If you don't plan on using your phat system while the truck is off, then you don't need to touch the battery or battery cables at all. If you do, you'll need a yellow top battery and beefed up cables to ground and the power distro box.

personally i have neither. i plan on upgrading the alternator and battery soon tho. what i know if just from reading on several forums and general consensus is no go on caps unless the electrical is already in place. From my understanding caps perform best when there is little to no voltage drop. where as a alt and bat will help decrease the drops.

thats if the "5 gallon bucket" has atleast 2 liters of water in the first place

You get a voltage drop when you exceed the capacity of the alternator, or I suppose if the load spikes faster than the voltage regulator can compensate. The purpose of the capacitor is to quickly fill in those drops. If the system was designed correctly in the first place, the alternator would be up to the job and this wouldn't be happening at all.

hence why you want to upgrade the alternator before adding a cap. if you want a system with over 300w then a stock amp is not gunna cut it in most cases. This is why i say HO alt
