    itll kill your alternator because its killing your battery and the alt is trying to hard to recharge it, but it'll only really kill it if you just sit there with your stereo alot.

    what size amps, what car, what alternator (if you know), and do you listen to your system turned up high frequently?

    Regardless of how big of amps you have, if you are listening to it without the car running, its going to draw alot of power, and it will kill your battery. Eventually, it will kill it to where it wont recharge. Your alternator strains greatly when you try to charge a dead battery with it as well. So yes, you can kill both by listening without having it running.

    Now, if your car starts and the battery isn't charging back to where you can start it again, then your alternator needs checked out. Having a bad alternator can cause the battery to go bad as well.

    Well what it comes down to is your overall current draw. The easy way is to check the fuses on the side of the amp, or check the owners manual to find the total output draw, you will have to add the two amps that you have together, I have two amps, one draws 100 amps, and the other draws 80 amps, so that would mean that I would have a max draw of 180 amps on my electrical system. If you alternator is only producing 90 amps, or basic system probably about 140, then you are requiring another 40 amps of draw when you use your system to its full extent. If your alternator is putting out 90, then you are gonna drain your battery very quickly. As your stereo is running, well if your draw is more then your alternator output, it is (1) gonna eventually kill your alternator, and (2) is gonna drain your battery. Your battery is never getting a full charge because your alternator is trying to keep up with your system. Hope that helped

    what you said above is common sense, and i can condense it to one line:

    if you run your system with the car not running, your battery will die.

    but i'm assuming he's a little more intelligent than that, which is why i asked the questions in my previous post.......
    anyway, two things to remember:

    1) a 240 amp alternator does not put 240 amps out at idle... the very high amperage alternators usually put out very low amps at idle

    2) a system isn't drawing max amount of amps when it's playing low. usually an amp that "draws 90 amps" is when it's going full blast, not on low volumes.

    Okay so who do you know that plays there stereo at low volumes. Most high output Alts will produce about 65% of there overall rating at Idle, and as you speed up your power will go up, but what I was talking about, is even if you are driving, and you are drawing more amperage then your Alternator is producing, then it will take the power from your battery. My concept has nothing to do with parking and listening to your stereo, it is if your draw is more, even if you are driving, it still is gonna kill your battery.

    i wasn't questioning your concept... i was just adding to it. i agree with you, just didn't want the guy to get the wrong ideas.

    who do i know that plays their stereo at low volumes? me. i don't listen to it at full blast at 24/7, because that's............stupid and inconsiderate. i don't like pissing people off with extremely loud music, and i don't like damaging my hearing by listening to it at full blast all the time.
    an amp that draws "90 amps" doesn't draw 90 amps whether it's full blast or at half its potential... the amount it draws differs according to volume.

    Common sense ISN'T always common. I never discount how little a person knows about a subject in the beginning. Anywho, I also do not listen to mine loud for similar reasons as been listed. My amp is rated for 60 amps of draw, yet it draws 108 amps on a burp.... guess you can't go by fusing can ya! It's drawing between 20-30 amps at the loudest level I listen to, plus the other 2 amps good for 25 amps of draw or so total at loudest listening level. So, I'm at 55 amps, PLUS the HU, processors, radar detector, lights, etc. I have a 60 amp alternator, why is my car fine? Playing music, you dont have a CONSTANT full draw, thats why I'm not killing the alternator. I have 2 batteries, those take the sudden hard load off the alternator.

    right. but if the amps constantly drew 55 amps, plus your headunit, lights, engine, radar detector, etc. that's another good 40 amps there... so if your system was constantly drawing 95 amps, then no, your alternator wouldn't be able to keep up, whether you have 1 battery or 10. but since you don't always listen to it loud, they're not constantly drawing 55 amps..... therefore you agree with me

    what are we arguing about?

    Not trying to bag, just wondering what amps are you using that are rated at 60 amps, drawing 20-30 amps max draw, but take a 108 amp draw on Burp, cause those are some incredible amps, again just wondering

    agree with mialac, + dont forget to upgrade all of your factory grounds, and wiring from your alternator to your battery

    If your on a tight budget try the alternator pulleys it will kick your alternator output up at lower engine rpms, thus charging back your battery quicker.For about $30.00 heres link:

    it looks like the wire that runs from the alternator to the battery is fried........would running to many watts/amps off of the factory battery cause this

    I said 20-30 amps at the loudest i listen to it, not max draw. Max draw would be the 108 amps on a burp. The amp is an Orion HCCA2100.

    Yes, excessive current draw will burn a wire.
