With 2k you would want to get an extra battery. A deep cycle battery in the 80-100AH range would be good. You could get a new one through something like XS power and pay quite a bit, or pick up one of the many used batts for sale on caraudioclassifieds.org.hey man i need some more help. I think i would rather go with an amp with 2000W rms, could you help me find something?
