I have come to a point where i would like to get rid of my starting system, question is though should I get a 15 inch sub, or keep my Rockford Fosgate PL2-212. If I do get the 15, should it be placed in a ported or sealed box? I would like to keep my budget below $200 for the sub. Or instead of getting the 15, should i get a new amp. My current amp is an older style power acoustic gothic series 520 watt max.
