### ⭐⭐⭐⭐⭐ 







  
  
    Great Product ............
  

*by P***A on Reviewed in the United States on July 9, 2018*

Sound is excellent. I used a wal mart amp and head unit i purchased locally named “Dual Media Player” and I was very impressed with the clarity. I am purchasing another pair for the rear of my boat.  I replaced a set of BOSS wake tower speakers that didn’t hold up to the salt.
