Speakers lower mpg

[Austinpg11]

Just replaced my stock speakers in my 1998 jeep Cherokee. The past few days I have been playing them and noticed that my gas mileage has been terrible. Is this because of the new speakers. I have also noticed my battery has been lower than normal.

You replaced just the speakers and nothing else?

Yea, your new higher rms speakers are now causing your fuel pump to work harder there for draining your battery faster. And since the fuel pump is working harder it might pumping more fuel than needs to be. You havnt had any sputter issues or the ****** acting funny?

Every thing has been normal other than gas mileage

Does this mean I should instal a high output alternator

changing speakers should have 0 impact on mpg unless your adding a large amount of weight or large draw on your charging system. If you disconnected your battery and it reset your ecu your vehicle could be running rich until a few run cycles causes the fuel map to readjust.

Yes, From the research I have done it seems to be putting lots of draw on my battery and my alternator can't keep up.

your alternator is less than 3 hp. its not affecting your milage.

I put 2000+ pounds of stereo equipment with 30,000 watts of draw and added a K&N air filter in my car. I noticed no gas mileage drop I must be doing something wrong or that air filter made up for everything!!!! Its MAGIC!
