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? |

batteries don't put out 14.4 - they put out 12.6 -- beyond that it's up to the alternator.
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. |
