PLEASE CONSIDER MANING A 4 INCH MARINE SPEAKER!! Skar speakers have the best bag for the money out of any brand I have used to date! My 2 - 4 inch Kickers running solely off the head unit are pathetic compared to the 2 - 6.5 and 2 - 8 inch running off a 4 channel 2400W amp. All I need is 2 - 4 inchers to complete the entire boat with Skar speakers. On another note, the shipping is fast, and the packaging is outstanding. The quality of the voice coil is apparent the moment you feel the weight of these speakers!! I would put this equipment in any car, boat, golf cart, you name it!
