dbslayerdrake Posted June 7, 2012 Author Report Share Posted June 7, 2012 Well that's what I'm wondering, if there's a way to look at the amp specs or the watts and figure out how much you will need. The amp in question is a DC 5.0k You bought a very very nice amp and dont even know the specs of it?? http://www.dcsoundlab.com/5k.html scroll down. the website lists them . . . they even give you a recomendation of what you should run!!! common man I haven't bought it yet. I know they give recommendations, but my mindset no matter what is research research research! I could easily look at the specs and everything on the site and assume that's that but I'm just not that comfortable. Quote Link to comment Share on other sites More sharing options...
dbslayerdrake Posted June 7, 2012 Author Report Share Posted June 7, 2012 I'm wondering, how do you know how much battery/alt power (amps or ah) you need to sufficiently supply a certain amplifier? I'm actually uploading a video on youtube that will explain this. XS Power gives a good wattage rating on their batts. You can use that as a guide and figure the alternator size required by the batteries you need to charge. Though you may be limited on alt size. General idea is that the MAX amps of a batt can translate to it's wattage capabilities. At least in a short time frame. It will be important to have a proper alt to keep that battery charged as the amplifiers are draining them. Example, a XS Power D3100 has a max amperage rating of 5000A. This is a short burst rating. XS Power rates it at 5000w capability. Notice this is NOT amperage times voltage. This is based off of a longer period of load time. If you take into account amplifier efficiency and other losses in the system. You can get a realistic 4200w with that battery while playing music for a long period of time with amplifiers that are 85% efficient. Now, you will need an alternator of at least 120a to feed that battery to a charge ratio of 1:1. This is approx how many minutes of charge it will take to top off the battery after that many minutes of full power play. So play at full tilt for 1 minute and it will need 1 minute to top off. Of course with 4200w you can play for several minutes. These numbers in the example are just figures based on my own calculations and would be a bit lower if you are also using that battery to run the engine. Thanks man. This helps a lot!
