[QUOTE="StevesCarAudio, post: 7504012, member: 632825"] Ok so I just wired up a new battery and feel like an idiot for asking as I have never had issues before in any other vehicle. And I usually ground to the body or strut tower in the trunk, but was told it was better to run all the way to the front to ground to the same ground as my starter battery. So I have a NSB-180FT battery in the trunk. I ran 1/0 up to the front to my postive terminal for power and grounded it to the frame ground that my starter battery grounds to in the engine bay. I have some alternator whine coming through the speakers. Is this because the audio battery ground is grounded on the same ground as the alternator/and all other engine components. Would it be better if I grounded it somewhere in the trunk? where would you recommend in the trunk of a 1999 Buick park avenue. I think that it would be better to ground in the trunk, but was told by a couple of the guys I work with in the shop that I needed to ground to the same ground as my starter battery. [/QUOTE]
