Question

Does having a system rob gas milage?

Answer 1

it does but its not noticeable since the system adds weight its like have a 10 year old kid in the car with you so it wont actually make u spend extra on gas

Answer 2

in extreme cases, very much so..

depends on the power consumption

I noticed a big difference back in my competition days, the gas mileage of the Honda I used dropped severely.

The weight added a decrease as well as the extra power drain.

This was with three alternators and 5 batteries.. Pushing over 7,000 watts

an average system would have little effect, more like a decimal difference

Answer 3

Has very little effect.  Suffer from added weight, but thats about it.  I've monitored fuel economy on my car pre-system, post-system.  The numbers haven't changed and my driving habits (agressive) have remained the same throughout.

Answer 4

it shouldn't, unless your system weighs like 1000 pounds, just stay away from homemade boxes that are oversized they are real heavy.

Answer 5

no it will just add extra weight
