I own a 15k and according to xs power they shine at around 11.8 so if your looking to get the most out of ur amp don't do it

To start this thread off this is not a bashing thread. I bought my xs15k knowing I was a Guinie pig. I also have 4 kinetik group 31s and a d4800 and a deka under the hood. I have 4 h/o alternators with 5 runs. Well my voltage sucks. So I called Xs power and they told me today 11.8 is good voltage and that the lithiums perform best under 12 volts. Long story short Amps are rated at 14.4 and not 11.8 and I need my Power I'm currently running 2 sundown 6ks and I decided today I will be selling all my batts and switching brands. To see how voltage improves.

I had mine unplugged for a long time but here lately it's doing better plugged in

I know I'm late but sick
