So my truck is a single cab pickup with 2 10's and 2000 watts plus my four channel and without the 4 channel my lights dim pretty bad, but my voltage meter never drops below 12V the stock electrical is a 145 amp alt big 3 except the alt to bat. 0/1 wiring delco 70ah batt
so im thinking about adding a battery in the back but because the 2 10's port are taking up all my room so will i notice a difference between a kinetik hc1800 and hc2000??
which battery should i be using and is it even going to help?
