HAHA BYE

The speakers in my E55 are only playing sound out of the back speakers like with no bass. I can hear it just fine but it wont play out of the the other speakers. Also the heated seats wont go on unless I press the passengers side first and if I press it again they both go off. ...weirdd...just started acting up. Do you guys think it could be my aux battery killing the sound and seats? or what?
Thanks guys

I had the exact same problem awhile back. It ended being the factory amplifier going bad. Take it to the dealer.
