Summary: Recently replaced existing pair of blown 6x9 speakers in fishing boat. At basically $30 each (I pd. $57 for pair) I was not expecting great sound, just better than blown out speakers. The grills on these are pretty flimsy; if mounting where they could get kicked I'd recommend something with a stronger face plate. Sound quality is OK - definitely not JL - but also not JL price. And these are really WHITE - way more white than any white gel coat.
Summary: I put a pair of these in an 18' Caravelle boat and they sound great. System includes 2 Boss MR50W 5.25-Inch 2-Way Marine Speakers, 2 Boss MR60W 6.5-Inch 2-Way Marine Speakers, Boss MR690 6" x 9" 2-Way Coaxial Marine Speaker hooked up to a MB Quart Marine NAU460 180-Watt A/B-Class 4-Channel Amplifier. Also have a Bazooka MAA1500 500-Watt Marine Mono Amplifier hooked up to a pair of Boss MR100 10-Inch Marine Subwoofers and I couldn't ask for a better sounding system.
