Music vs. Fuel Mileage

[led_fut]

Any one think that having the subs cranked will affect fuel mileage?

I just put about 800 kms on a tank... and for the last half or so i turned the subs off/really low. usually i can barely squeak out 700 kms. this is on a long back country road trip that i do alot (8 hours there and back).

the only thing i can think of that affected it is the lack of pound (400w, 2 tens). 57 litres to fill up.

wondering if anyone has similar experience

accessories technically use more gas.

if you have your head lights on, your music blaring, it is taking more from the battery, thus making the alternator have to replace that power. Since the draw is higher, the alternator has to create a higher load to create the power, thus making your engine have to work harder.

I don't think it would make that much of a difference, but technically, you use more gas with accessories on

so just turning down the stereo is giving me 3 mpg more lol.... awesome. in a quiet sort of way.

yes it will affect mileage. the strain from on the altornator uses more gas.

so its probably good for the ol' alternator that i dont have the stereo cranked for extended periods of time... anyone cooked theirs? i usually have it loud enough that i wont hear my phone sitting on the passenger seat. lol

wow this is interesting i never thought about this i new the more weight you put in yor car the more the car struggle to run and it takes more gas but i never actually thought about this is... good to know

The difference wont even be noticeable. Making sure your tires are inflated enough would make much more of a difference.

i beg to differ... my car is top notch running condition (tires 32psi, just changed the oil a month ago, newer 02 sensor, plugs, cap, rotor, alignment). and i make this trip at least every two weeks. so all of the sudden im getting 33 instead of 29mpg?

and i have noticed sometimes the car surges a little when im sitting at the intersection with the tunes cranked. so yeah, the stereo is definitely putting load on the system

probably not with a stock stereo, but with a big stereo eating a lot of amps I bet this would make a noticible difference.

x2. My phone is always on vibrate and in my pocket in the car. But, yes... I fried my alt in my 240 on a 4 hour trip back home with the music as loud as it'd go without getting distorted to stay awake. About 30 mins from my house smoke is everywhere. Alt was bright orange and the belt and intake box were metling.

3 Type-X 10's
But, I sold them with the 240.

I don't run any subs right now, but I'm buying a friends Memphis 10's to get a little bump.

a system will effect your gas mileage.. I had a 240 with a decent system in it and there was a big difference in gas mileage depending on how loud my music was.. But my alternator was pretty much fried too

seeing a common thread here with the 240 alternators... anyone have issues with the cb7 alternator?
