Hey I have a supercrew sound box for 2 10s and right now I have 2 kicker comp cvrs, and they hit hard but it says they need atleast .85 or airspace and the box I have only has enough for .60 airspace a sub. Would that be the difference? Would it hit it harder if the air space was right or is .25 not that big of a deal? Also would the Rockford fosgate subs be better than the kickers, I want really loud and hard hitting, they only need .50 airspace. Let me know what yall think

 

yes they would hit harder with that extra .25 cu ft.

 

which rockfords the p1's or p3's. P3's sound really good if you have a large enough amp to them. I am personally a fan of alpine type R subs. They do not need much air space and sound great.

 

they are 10 inch p2s, the dual 4 ohm
