I'm in the process of getting a seat box constructed for a Sundown SA 12 I have from another set up. I'm having a custom made box constructed for this build of course. I would like to upgrade the 12 to either a Soundqubed HDX 12 or the new 2018 SSA Icon 12. The person who is building will modify the cutout for my upgrade later. I would like to know should I go with SA 12 or go with the other 2 subs and which one. This is my first time going with one subwoofer and this also my first truck. My last set up was a dual SA 12 in a custom box in a chevy impala.
