Review on PLMR692 Dual Marine Speakers: 6x9 Inch, Waterproof, 260 Watt Power, Outdoor Audio Stereo Sound System - 1 Pair by Daniel Shivashankar

These speakers sound damn good. Now I can really feel the vibrations in the seats they are installed in. The back is slightly larger than the polks I replaced and will require additional sawing. never mind The included cable is not worth the space it takes up in the box. Get a good 16 or 18 ga cable and make sure the quick connectors you have will fit the speaker studs! They only contain four screws, which are great for just attaching the speaker to the wood substrate - they're too short to go through the speaker grill and then to the mounting surface. I ended up using a couple of my own 1.5" stainless steel screws to attach the cover and then the speaker to the bracket.
