My car radio runs on electricity. Not gas. So it don't burn no gas.

If you leave your radio off you'll get better gas mileage than if you had a Tesla radio.

Yes, it does "burn gas". The electricity it runs on is generated by your alternator which is turned by your engine which runs on gas. So it burns gas.

My guess is though that even if you're a moron with boosted bass speakers and a 3000W amp turned up all the way, you're going to lose about .1 mpg.

You're going to lose more mileage due to the added weight of the subs, enclosure and amplifier than the negligible amount you will from the current draw on the amp

Help me understand that one. The alternator is driven by the drive belt. Its speed of operation is governed by the speed of the engine. I am assuming a normally functioning car without excessive electrical demands.

The A/C affecting gas mileage I understand. The A/C compressor clutch minimizes friction on the drive belt when the A/C compressor is not working. the alternator does not have a clutch that disengages the alternator when electrical generation is not needed. The alternator's "clutch" instead allows the alternator to continue to spin at higher speeds when the engine speed suddenly decelerates. So where is the source of increased friction from increased electrical generation that would affect gas mileage.

I am assuming a normally operating car and that the total electrical demands are not excessive.

Marconi invented the radio.

Tesla invented the rock band AC/DC so you could hear it on the radio.

If you park your car in the shade your radio won't burn.

Ok energy is conserved. You don’t get something for nothing. When there is more power drawn from the alternator, it takes more energy to turn it. There is no free lunch. If you draw energy from that energy from that engine whether it’s in motion or electricity it will come from the gasoline.
You’ve ever taken physics. Or you’ve never built a generator. If you have a hand cranked generator, you can hook it up to a 100 way draw or a 200 watt draw. You have to crank harder for the 200W draw.

So what I wrote is not the clearest. I’ll just stick with energy is conserved.

For a moment, say you decide you want to amplify the shit out of your radio. You install a big ass amp and 2 competition 12 subwoofers, when the bass hits does your engine rpm go up? Lmfao of course not, the headlights and dash lights will dim because wait for it, the alternator can't magically pull more from the motor to meet the demand. So in order to correct this you need to either...
Install a larger custom alternator for the load, or...
Install a capacitor to store the excess electricity generated by the alternator when the bass doesn't hit.
Go the fuck back to physics class son.

The energy going into the speakers has to come from somewhere. It comes from the gasoline in the tank. Where else did it come from? The energy that the speakers used is not available to move the vehicle. So you get poorer gas mileage if the speakers are blasting.

You’re the one who needs to study physics.

The alternator does not have any control on the rpm, it is static, not dynamic. It can not speed up the motor and affect mileage. It has the same exact load on your engine regardless of how hard you push it, so you use caps to store the excess electricity generated when it's not at full demand and when you go over its ability you will see the lights dim to correspond with the audio demand.
Tldr: the radio has some load by proxy of being powered by the alternator but that load will NOT change in any way short of replacing your alternator with a bigger one.
So no bitch carry your ass back to school. I'm a card carrying electrician in virginia for over 20 years in ac and dc low voltage controls

So again, where does the energy that drives the speakers come from?

It comes from the alternator, but what you aren't understanding is that the alternator is the limit and doesn't change how it draws from the motor depending on its load. That's why the lights will dim when the bass hits if you max it out. The alternator is oversized for the electrical demands of the car so there is an excess being generated while the car is powering its normal load, so this isn't free energy, you add capacitors to store the excess that's typically wasted energy. If you add too much audio equipment for the alternator to power with capacitors you will have to buy a higher amperage alternator or get it rebuilt with custom windings. Changing the alternator is the only way to affect your mileage with audio equipment (ignoring the mileage loss from added weight which is irrelevant to this specific conversation)

Test it yourself. Set your vehicle to display current mpg. Set your cruise control. Now turn the volume up on the radio. $100 says it didn't change. Also, I bet your rpms didn't go up lol

You don’t understand the 2nd law. You can’t drive the speakers from nothing. The speakers use energy that comes from the gasoline in the tank. The gasoline that generated the energy that drives the speakers is not available to move the vehicle. So the vehicle using speakers gets lower gas mileage. Sorry. It’s that simple. But you don’t get it. I’m betting that you think that the election was stolen too.

Dumb ass, we already established that the amount of decrease in gas mileage is minuscule. Way smaller than anything like a tach or s mileage gauge could measure. Moron.

I told you this answer like 5 times already. It's not from nothing, the alternator is powered by the gas but it's a constant, the speakers the amps, the radio, none of that is going to change the amount of draw the alternator puts on the motor, the alternators load does not change just because the load ON the alternator changes. You are already using that energy

Says the guy who think the alternator is a dynamic load

Three Questions:

1. Does the electrical load on the alternator vary? Answer: Yes, the more electricity being drawn on it (by things like speakers and headlights) the greater the electrical load will be on the alternator.

2. Is there more resistance to turning the alternator when the electrical load on the alternator is higher? Answer: Yes. Lentz's law, and obviousness, tells you that if the coils in the alternator are carrying more current there will be more resistance to the coils moving in the magnetic field in the alternator. Meaning it will be harder to turn (rotate).

3. If there is more resistance to turning/rotation, does it take more energy to keep the alternator turning/rotating? Answer: Duh.

4. Where does the additional energy come from when the resistance to turning is higher in the alternator? Answer: Duh. The vehicle uses more gasoline.

I tried to pour gas into the radio in my 78 Ford LTD and it blew out the speakers.

Why didn't you simply go with the increased demand for electricity increases the resistance in the alternator which in turn increases the friction on the drive belt which requires the engine to run slightly faster. The problem with many of these "I am so smart and you are stupid simple answers" is that they are given to people smart enough to know those "simple answers" are not the correct answer. There is almost always some key element that is missing from the simple answer.

Because unless you spell it out in discrete steps you’ll always get back a meaningless “answer” that they’ll say you didn’t address. Like in response to your post they’ll say something like “the load on the alternator is not dynamic”. It won’t mean anything but they think they’ve proved you wrong.
