Just finished winter stereo upgrade last weekend and all I can say is WOW! Came from stock amp powering 4 6.5" in boats and 2 6.5" can on the tower,with bow speakers running off of Head unit. Added a JL 12w3 and pair of rev 10s powered by a JL 700/5 amp. Also added a WS420SQ, custom built ported enclosure for sub, new kickplate, and amp rack since the stock amp was just mounted to the back of the front seat. After contemplating spending the money on everything, I am more than happy with how the overall project turned out. It was the first time I heard a pair of the Rev speakers and I am extremely happy I went wit them. My brother did an excellent job on enclosure and amp rack, which picture of amps is before all wires were cleaned up. If only the weather in Chicago/NW IN would cooperate now so we could get the boat on the water....
HUGE thanks to David and Odin at Earmark for making sure we got all of the items we needed and for helping more than I could have ever asked as far building correct enclosure, wiring everything, and tuning the system after it was complete. I asked so many questions I was starting to feel bad but they were more than willing to help out every time and we learned a lot from this install.
