I'm running a2100 watt hifonics at two ohms. Pushing two 10" kicker cvx subs. My amp is only running at 1400 watts because my subs are dual 2 ohm subs. I'm debating on adding two more tens either in the ext cab of my 1997 s10 in a custom box or doing a blow through. My second choice is moving on to different subs. What do you guys think, help me out. Thanks in advance.
