Im about to do a full system in my car and the only part I can't decide on is whether to go for the new Sundown Audio Z v.4 15" or the Sound Solutions Audio Evil 15"..

Whats peoples thoughts on the two in comparison?

 

Decided, getting the SSA sub. Admin can delete thread.

 

Good choice, I had the cheaper Fi version Sp4 and it was nasty on 2k and got even nastier on 4k.
