Re: High Power Output alternator

Why do you need a high power alt?

Re: High Power Output alternator

I'm putting in a system. It can achieve about 1100 watts RMS. I also have a farad cap. I doubt I'll ever be pumping it that high put I figured I'd probably need a high output alty for my system. Maybe I don't though.

Re: High Power Output alternator

Id say put a power cap on it and you should be fine. Idk what your ententions are but if you trying to blow out the back window with the sub htting 24'7 and at its max potentional you might need one but a moderdate bump the stock alt should keep up with it just fine from my exp with systems

but try ebay or get specs from other cars. IDK if this will work but a smaller pully to make the coil in side spin faster creating more energy?

Re: High Power Output alternator

I read on the net if you have a cap that's even more strain on the alternator. I don't know but what I'll do is set my system up with the stock alty. If that seems to not be cutting it I will upgrade.

Re: High Power Output alternator

I wouldnt be woried about cutting out because the cap will make up for loss power. Id be worried about not starting my car one day because you have no power.

Re: High Power Output alternator

thats true...the system might suck so much juice that the alternator can't charge the battery right?

Re: High Power Output alternator

yes it will burn out the alt faster, I had a 1000 watt amp on a kicker solo baric with a cap and i didnt have any problems with the alt but i also only had it in for a few months.

Re: High Power Output alternator

just my opinion but I hate systems where I can be in my car 3 lanes over and their sub is hitting so hard i feel it in my chest. That just sounds like crap to me.

Re: High Power Output alternator

Agreed - and if you find a site tell me, cause I need one as well soon. Mine is going out and I figure my system is Straight and full 1000 watts with a 1.5 and I would like to have a little insurance, lol. I found one a while ago, I think it was like $130 or something, don't remember...

I /sigh at caps. You're charging system can either handle it or it can't. I suggest a better alternator and battery.

Re: High Power Output alternator

Firstly, I'm running 950WRMS in my car, no capacitor and stock alternator

Secondly, keep in mind that when the car's running, all power comes from the alternator, not the cap. The cap is only required if you use the system for large amounts of time without the alternator running.

Think of it this way, a battery's is like your grandmother with money, slowly acumulates it, and slowly spends it. A capacitor is a cheap girlfirend by comparison - collects as much power as it can hold as quick as it can get it, but as soon as there's any drain, spends all it's power just as quickly.

Well, I'm pretty sure that's the way it works anyway

Re: High Power Output alternator

Caps give an extra boost when the amp needs it, how can you sight that?
Its not apart of making it run all the time.Like your alt and battery do

Re: High Power Output alternator

caps are false hopes. they do help i certain situations and are recommended, however, they do not ADD any power to the car. the alternator is still creating the power that is being stored and discharged from the cap. the cap simply controls (or manipulates) the power which still pulls power away from everything else....the obviouls effects are seeing the headlights dim but it also takes away from the entire electrical system of the car.....even the distributor.

I highly recommend a HA alternator even if your amp is only pulling 200 watts. it is just better for the car all around.

The factory one for th H22 produces 13.5 Volts at 100 amps.
I reccommend 14.4V @ 140 Amps.

I've only seen one premanufactured for 5th gens and i cant even find it now..BUT

these sites can custom make them to your specs.

Re: High Power Output alternator

well yes, I was just quoting the service manual. realistically it is 14.4V at X rpm. at idle though it is going to be just shy

Re: High Power Output alternator

finally some sense, Mdtdnd and Brash are pretty much right on.

Capacitors are another Load for your cars charging system, they DO NOT help it at all! Period! It isn't even a good bandaid fix.

READ: It is ANOTHER Load on your charging system and is counterproductive, ie: detrimental, to an adequate charging/power supply system!

If your amplifier needed additional capacitance, the manufacturer would have put it in the case or included it with the amp. Go ahead and open up your amplifier and tell me where they put a 1 farad capacitor... lol.. THEY DON'T because it is NOT necessary and it does NOT help.
If you have one hooked up.. take it out and sell it to some other schmuck that knows nothing about electricity and buy some larger gauge wire. Sorry to be harsh, but this comes up on so many forums and people actually belive the myth that the cap is helping them. *sigh*

If you are on a budget and want to help your electrical system, the FIRST and FOREMOST upgrade you should do is the big three power upgrade. Period, there is NO better first upgrade to your charging system. the wire is the highway in which your electricity travels and if it is congested (read resistance) then a new battery or alternator will not help very much.
After you have invested in new and larger wiring, THEN change the battery for a NEW one with fresh cells. There are many designed for the automotive environment that also are designed to power a mobile stereo system. Again, think of it in terms of reducing, or removing the worst bottlenecks first.

Now, with all that finished, if you are still experiencing dimming of the lights, or a drop in active voltage (usually under 10.5 Volts) THEN get your alternator re-wound, or find an aftermarket alternator to kick up the amperage.


and I am not just speaking out of some rear-ward facing orrifice, I held an electricians license during my employ in an industry where capacitors were a MUST; and required to make my pumping systems work/start.
