I currently have 2 jl 12 w6 and all m6 lit speakers. Took the boat out for the first time this weekend and the system rocked but in the bow their was of course a lack of thump. I am considering adding a 8w3 either ported or sealed on both sides of the bow or an m6 8ib lit with no box. Anyone done or seen anything like this in person. I’ve seen liquid rides and Spokane audio do this with 8w7 but I don’t want to give up that much space. I’ve considered putting a shallow mount but from research they have less output than a traditional woofer. Any feedback on this would be great. A 10w6 ported under the bowfiller cushion is my first choice but I don’t think it’ll fit. Amp will be either m1000/1 or m600/1 depending on sub choice. My concerns are storage loss and the added bass being non existing. I know it won’t be a lot but it will be some and a lil more on top of the 2 12s
