Thread: best battery for under the hood?

lmao... yes I have. Are you suggesting that our alternators supply 120 amps continuously, even at idle? No, they do not. When the draw that serious... aka, a need for a quick discharge to satisfy a power-hungry amplifier, occurs if he is at idle, where oh where will that extra amperage come from? Also, yes, voltage does drop below 11v without a sufficient electrical system... if it never happened, and was impossible, as you imply, then there would be no need for the protection circuit concerning low voltage. If you've never heard of a system capable of causing a voltage drop to below 11v, I question how many large systems you have personally been involved with.I addressed the issue at hand perfectly: a stock battery and a 120amp alternator is not sufficient to run 2600 watts on a daily basis. If the OP does this, you can be the first to offer up every explanation in the world to why his equipment should not have failed when something goes wrong.

Not at all!! I was wondering when this would come up :>

But with that said, ever clamped to see the AVERAGE pull of an amplifer? An alternator can't keep up with a quick discharge? Now we're talking about the voltage regulator. A well built power supply on the amplifier should have the necessary capacitance built in. A battery is in no way comparable to a capacitor.

As far as 11V goes...I've been talking about the engine running this whole time. Not the engine off. That's why 11V isn't a valid issue at this point in time.
