[QUOTE="Heathen, post: 8754916, member: 680849"] I've just bought an amplifier which states how much power it makes at a given voltage (13.4v). As this amp will be run from my second battery (max ~12.5v?), I'll never see the full potential of the amp, unless I run it directly from the alternator, right? If I'm only able to power the amp from this second battery, is there formula to work out how much power I can extract at a certain voltage? Also, the amp recommends 'at least 150Ah of battery power', and two 200 amp fuses. My second battery is 50Ah. Even if I only run my amp to half of it's potential, am I going to wreck the battery? Am I even going to reach half of the amp's potential? I'm not able to get a larger battery just yet, so alternatives are not an option at this stage. I have to work with what I have. [/QUOTE]
