I Received My Kicker 12 Subwoofers In A Box And They Were Smoking Once Installed. When You I Contacted Them To Return The Item, They Sent Me The Same Ones Back. I Had To Send To Kicker Tech Support To Get New Ones. When I Sent To Kicker Tech Support, I Had To Pay Out Of Pocket To Ship Them There. The Customer Service Is Horrible. This Place Is Whack. DO NOT PURCHASE ITEMS FROM THEM! Its A Ripoff!
