Lex Carroll New member Username: Lexdiamond Post Number: 3 Registered: May-07	Posted on Thursday, May 10, 2007 - 03:20 GMT I have two amplifiers, an Alpine PDX-2.150 and an Alpine PDX-1.1000 (1300 RMS @ 14.4v) and a 160 watt DC-DC power supply running a computer with many peripherals. What do i need for alternator power or battery(I have a yellow top) How do I get the battery to put out 14.4v instead of 12v?

As for alt size -- in an average car I would think 150A would be plenty. If you don't have extreme listening habits a common 110-130A stock alt would likely do the job.
