Can a stereo system really weigh down on the electrical system and result in worse mileage?...

MetroMPG · 12-10-2012, 09:10 PM

Yes. But the big question is "how much worse?"

Remember: anything electric in a conventional car is powered by fuel burned in the engine: e.g. lights, heater fan, electric window defroster, power for the ECU, sound system. The higher the electric load, the more fuel needs to be burned to support it.

So yes, blasting a stereo consumes more fuel than not blasting a stereo. But the difference is small enough you probably couldn't measure the difference.

And you have to ask yourself, what is it worth?

One thing also to consider, when you've got say an amp and a sub with 2-4 speakers going, that's quite a draw on your battery if you do any EOC. And like WeatherSpotter found out with just headlights, the time the engine is running with P&G might not be enough to keep the battery charged over a long distance. So, if you want a sound system, and you do very much EOC, you may have to add 1-2 deep cycle batteries depending on load, distance, EOC time, etc.

I'm still deciding if it's worth transferring my nice sound system from RAVadoodle to the CRX. As much as I love my sub, I probably will leave the sound system in the auto vehicle.

I've gone without music before... Never again. Haha.. I drive a lot. So I guess I will just try and find amps that consume minimal power and don't cost me a million bucks...

So here is a photo of my current sound system..
JBL MS62C with passive crossovers straight to the Kenwood Deck..

And this is the sub and amp... It was free from my uncle so its working for now.

And I FINALLY put my door panels on! I was hesitant because they need redone but I am very glad I did.. The ride is soooo much quieter. It looks more complete too..

Looks great. Hard to believe the car is as old as it really is after the work you've done.

The thing to remember about music is that its dynamic. My last system had 900 watts on tap for the peaks. But even with compressed metal, the most it was using on average was 225 watts, and that's with the volume all the way up. That's about the same as running the car with the lights on, when you add up all the little accessory lights and the fogs. That's with loudness wars era music. With classic rock, etc, the most you'd use on average is 50-100 watts, even at full volume.

One other suggestion, if you like a lot of bass, is to keep an eye out for a ported box for your sub. It allows the sub to give you more bang for your buck.

I found that the tones were deeper and just sounded better. The air flow it gives off is fun too.

I see I see... You should see my car shudder when I turn the lights on at an idle... haha I am just hoping my system won't impact that any more, but testing it last night, turning the volume up had no effect so...
