|I replaced the OEM 5.25" speakers in my boat with these and was very impressed. These little speakers rock and are by far the best you can get for the money. I am very picky about my music and want nothing but good sound...these speakers provide that. This winter I will buy another pair and install them with an amp and a sub in the boat.|
