Finally upgraded the stock Roswell tower speakers to wet sound rev8 speakers and Sinister SD2 amp (400w rms). The head unit is a Rockford Fosgate PMX-5 with a PMX-1R remote on the driver side. It has two zones so the towers are on a separate zone (locked to zone 1 source) with independent volume control. Inside the boat are six 6.5" Rockford Fosgates with a 10" Kicker sub driven from a Kicker KX M800.5 amp. Install: Had to drill some holes in the tower for the new placement but all went well. Debated placement of the speakers but decided to stay with the classic placement. Drilled 3/4" holes (matching factory) to give me room to adjust the angle a bit. I'm hoping since they are bigger I will be more aware that they are there and hit my head less. Installing the amp was a little more tricky in the confined space. I added a stinger 150amp circuit breaker, so if it pops it’s just a flip to back in action. I plan to build a box around the sub to help with the punch, like Wylie_Tunes shows in his post. I will also be adding another bow cushion to cover the walkway to hide the bonus sumo bag I have up front and make it easy to walk up front. I’ll take more pictures of the rest of the stereo system but here’s a tease.
