Stock electrical handle 2600 watt rms?

[PSturmer 10+ year member]

No, I'm not telling you that, but for all the extra amps he's drawing off the batteries, he's drawing as many amps from the altenator trying to recharge those two batteries.
Do you get it now? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

you do not an alternator to put out as much as your system has the potential to draw. you are an idiot for thinking this. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif:laugh:

You sir are a stupid *** and if the OP listens to you, he is just as ignorant.

You should be banned for giving bad advice. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

BoomBoomBoy is correct in his math. Batteries can work in situations where alternators cannot be upgraded, it is just important to remember that you have to give the alt time to bring the batteries up. If you let the system depleat the batts low enough without giving the insufficient alternator time to catch up, you will smoke the alternator. Using a battery charger to bring the batteries up before starting the car is another way to make it work, but is not very practical.

The cheapest easiest way would be to add a couple batteries, but it will require you to use them properly and excersize self controll when playing at full volume levels.

I got a 110 stock amp alternator. ill be running a pdx 4.150 and a bxi-2008d. So 2600 watt rms. I can't get a mechman kit, the local alternator shop says they won't rewind or upgrade my alternator due to it being special and they say it will cause driveability problems (05 acura rsx base). The wiring will be all 2/0 welding wire with the big 3 done in 2/0 welding wire as well.
Is there any way to make this system work??? Do i need x number of batteries??? what can be done!?

Please someone help a fellow audio lover out!

2600 watt is a strain on stock electrical. do the big 3 and 2 good batts, you should be good.

A second battery is only going to work if you plan on running your car at 12.6V instead of 13.8V/14.4V. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

ALL power should be supplied by the alternator while the car is running, and from the batteries when the car is off. The only time the batteries are depleting their stored power is when your voltage drops to 12.6V or so.

that is the point BOOMBOOM was making. Amps will run fine on 12.5 vdc. the only down side to having a smaller alt is the time it takes to recharge a battery.

Adding a second battery is no solution. You've doubled the load on the charging circuit. Second batteries only help engine off situations. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

AGM batteries have less internal resistance than stock batteries, you can therefore have a larger or multiple batteries with no more of a load on the alternator than the OEM battery.

at least up date the under the hood batt and one in the rear and you should be ok, but i would look into gettin a alt

yeah i got a weak 80a stock alt and they dont make a ho for my car, i got a powermaster 5100r under the hood and gonna do a d925 in the rear, grounds are 1/0 under the hood, couldnt get to the alt

Keep telling yourself that //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

well, so far i got a deka intimidator in the front and a kinetik 2400 in the back, run with 2/0. Debating if i get the ebay 165 amp rewound direct fit or get the mechman 250 and have to fashion a bracket for the car.

whatcha think?

BBB - give it a rest already.

You're taking an over simplified theory and trying to apply it to a situation you don't seem to understand very clearly.

It takes current to charge a battery - given.

However, it takes significantly more current to charge a weak and/or cheap battery (~5A) than a strong and/or high quality battery (1A or less).

A 2nd STRONG, GOOD QUALITY battery WILL help an undersized alternator because when the alt is maxed out (which happens at high volume even for those of us running 1000w systems) the batteries are quicker and more efficient in responding to the current demand, and take less time/current to recharge once the voltage comes back up.

IF the system were BLASTED for an extended period of time, maxing out the alternator AND drawing excessive current from the battery or batteries - only at that point would the effect of having two WEAK batteries that needed to be recharged be a detriment to the alternator, and an effort should be made to avoid that situation because once the batteries are weakened the alt would be fighting an uphill battle.

Is it a good idea to just add batteries when running a lot of power? No. But if there are limitations on what can be done with the alternator - a better main battery and/or good quality 2nd battery can and will assist the alternator.

im drawing about 2700-3000w rms in my teg off a stock alt, all i have is a stinger batt under hood, and a SVR in the back.

i have no dimming issues and i drop down to about 11.5 when im wangin on it..

In exercising self control and giving the alternator time to catch up what do you or anyone for that matter suggest to help keep the batteries charged and not hurt your alternator at high volumes??? My thought is to drive around for awhile with the stereo off to recharge the battery or not blast longer than 20 minutes. Am I wrong or right??

Thanks for the responses guys!

I don't care what you disagree with. Have you ever taken a basic electrical class?
Batteries are a load on an alternator. Batteries don't even come into play until the car is shut off.

While a car is running almost all of it's power is from the altenator. Adding a second battery, only adds to the load of what an alternator has to supply electricity with until it's completely charged.

You really shouldn't give advice until you fully understand a car's electrical system.

Otherwise you're just giving bad advice. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Oh and do keep in mind that the car will also require some amount of power as well...
