[QUOTE="Glentract, post: 8247175, member: 659936"] My girlfriends car is a 2010 Altima with the 4cyl engine. It has a 110amp alternator and definitely has some pretty seriously voltage drop with a Hifonics GLX1400.1 and Cerwin Vega 4 channel. She's got a brand new slightly bigger than OEM duralast gold and 4 gauge wiring. I think those cars just don't have a lot of left over juice. Idk what to do in her case. Thought about a second battery but not sure if it'd help as I think the alternator is just too small. Her system is definitely pulling more than 60 amps though. Maybe a new battery (biggest you can get) would help in your case. [/QUOTE]
