Krisztián Arnold Posted April 29, 2018 Author Report Share Posted April 29, 2018 Just now, Rosati21 said: but on the box is doesn't say 2000 watts rms or max. based on most hifonics amps I have installed most done hit the rating on the box or in the manual. So let's say it does only half of the power. I still can not see that either. Link to comment Share on other sites More sharing options...
slowfkncar Posted April 30, 2018 Report Share Posted April 30, 2018 impedance curve can change significantly when going from a 130cf cabin to a 2000cf room. Link to comment Share on other sites More sharing options...
SkarredSierra Posted April 30, 2018 Report Share Posted April 30, 2018 You dont have 14v like you would in a car. Most good agms only rest around 12.8 or so. That little battery maintainer isnt doin shit. Your going to ruin your batt by constantly draining it. You could also damage your equipment because of the low voltage. A dmm doesnt read rms and isnt a proper way to set gains. The carts like steve uses to test amps are specifically made for that. And he uses a 14v batt bank with a strong maintainer and only runs for short periods. Link to comment Share on other sites More sharing options...

Also, if the battery is not capable to run 1000W-2000W amps, than why does XS power sell them like that? Link to comment Share on other sites More sharing options...
SkarredSierra Posted April 30, 2018 Report Share Posted April 30, 2018 Those ratings are based off of being in a car with an altenator to help keep them charged. Even in a vehicle if the alt isnt powerful enough to keep up with current demand the batts will drain and youll have the same issues. Link to comment Share on other sites More sharing options...

I've got a PC to be honest, and I did not measure it just yet. Do you think, that the input voltage is too low, or distorted? Link to comment Share on other sites More sharing options...
