[QUOTE="Jasdip, post: 8651448, member: 675380"] I have a 2011 Range Rover Supercharged (full size) and for like 5-6 years I didn't have any problems but now when I am accelerating, the vehicle slightly jerks when the subwoofer hits. If I am driving at a constant speed, you can feel the vehicle lose some power as if you let off the gas and on again very quick or quickly tapped the brake; you can also see the bump in the RPM on the gauge as well. When climbing a hill, it is very noticeable too. We first thought it was an old battery problem and replaced the battery; that didn't help. Next, we found out the alternator had issues and that was replaced with a new one; that didn't help with the jerking. I am about to purchase a new capacitor, likley a 3 farad and installing that to see if it gets better. Does anyone have any idea where the problem might be? The set up is as follows: 2 Alpine Type X suboofers 2 Alpine PDXM12 1200W amplifiers 1 Farad Pheonix Gold Capacitor Thank you. [/QUOTE]
