need help picking a 15 sub
 

I'm currently trying to decide on a 15 to get.. I have a Rockford prime 500.1 that does 600 at 2 ohm I also have a huge octo port box tuned low, guessing 26 to 28 and had a RE in it and also a soundqubed hds200 and they both slapped nice and low but the soundqubed blew on me(my bad for setting stuff on it in the garage:( ) so I'm deciding on the soundqubed hds300 15 I would be underpowering it big time or a sundown e series 15 my budget is limited so I'm trying to stay under 170$ and the soundqubed seems the best option any input here please???
