speakers, and it not only looks great, but sounds great as well!! My wife even said she likes the way it looks. Sound is terrific. The other thing I like is this, although you have to plug it into the A/C, upon further review, the transformer steps it down from 110 ac to 12 v dc!! there you go, just get a patch cord and plug it into the DC outlet on your car boat, RV etc!! Now it really kicks ass!!. I plan to use my tailgating, I wanted to add some tunes but most of the big volume blue tooth speakers were just too big. now just plug it in to the outlet in the back of the car and Thuderstuck away!!!
