[QUOTE="n2audio, post: 8379121, member: 540940"] Unless you play it at grandma volume all the time - Your alt isn't going to last long. It's that simple -- one battery or 5. A few months maybe, possibly weeks. The extra batteries are only involved AFTER the alternator is already maxed out. I've been running ~1500w for over 10 yrs now in 4 different cars. The 110A alt in the 1st car held up the longest. I never had to replace it over 3 yrs or so. 110A alt in the 2nd car had to be replaced once over 3-4 yrs. 130A alt in the 3rd car got replaced twice in 3 yrs. Current car I've had for 8 mo has 160A alt which hasn't been replaced yet and shows no sign of weakness -- BARELY any dimming at full volume, all stock wiring. [/QUOTE]
