what are the best subs for the minimal amount of money, and where can i get them? wont be getting as much as thought with income tax, and i wanna try to replace or add 2 more of these kicker comp 10's. i was looking at them $20-$30 hifonics, but they aren't available in 10's. if anything, the most i could spend would be $150-$200 on another set of 10's in a box. would prefer another set of comps in a kicker manufactured box with the port until i get the box built that i want for 4 10's. just looking for as much information as possible. thanks in advance.
