dimming lights help ???

I'm runnin a less powerful amp than you are right now and even with the big 3 done I still had dimming till I added those batts

I personally don't think you need 4 tho, I just put them in bc I had them sittin here

no i dont think i have that much power to need more batteries .lol

1579w / 12 volts = 131 amps of current...

your alt is 110 and an hc1800 battery... take away the 90 amps that the vehicle requires and you are left with just the 1800 battery and 20 spare amps from the alt if it is at 100% output all the time...

you need to find the wiring issue... I have seen 300 amp draw setups with smaller alts and equal battery capacity do just fine...

I don't mean to argue, but more batts cannot stop dimming. It's physically impossible. You might notice it less, but it's still there.

correct but neither will a bigger alternator..

batts store the energy and release it extremely fast

alternators just generate energy for the batts to store..

Not true. Alternators are the highest source of potential in the circuit. Therefore while an alternator remains the highest source of potential in the circuit all current is drawn from it. Dimming occurs when the voltage drops. If the alternator can supply enough current for the amplifier to draw, the voltage does not drop and you get no dimming. It's very simple. Your statement is silly.

a battery is the highest "potential" because it is renewable... it takes very little alterator current ( amps ) to charge and maintain an AGM battery which in turn releases very large amounts of current nearly instantly due to the nature of their low ESR design.... something even the biggest alternator will never be capable of..

if he has 131 amps of draw from the amplifier all the time he needs at least double that in reserve...

by your logic no one would ever need batts and they would not exist because there would be no market for them...the opposite is more true..

in his situation he needs more storage not more generation... he is generating plenty of power and current and has no way to store it for the transient peaks ...

might wanna look and see how small the current needs are to charge and maintain an AGM battery...

as little as 1-10 amps at 110% usage...

Potential = voltage. So you're incorrect.... badly.

Totally irrelevant for the discussion. Since the alternator is the highest source of potential, the battery does not discharge until the system voltage reaches it's float charge which will be down at 13v or less.

if he has 131 amps of draw from the amplifier all the time he needs at least double that in reserve...

Maybe for a second or two.

I'm not using "logic". I'm using facts proven by science. The reason batteries are in the equation is because alternators are expensive.

in his situation he needs more storage not more generation... he is generating plenty of power and current and has no way to store it for the transient peaks ...

That is a totally nonsensical statement and you need to brush up on your electronics knowledge. This is laughable.

I agree with ecrack 100%, sicaudio just does not want to learn or something, ive tried to tell him before...

Like to see you start your car without a battery.

That's about all your battery is good for btw, to start the car and run any electronics while the car is not running.
