Deep and powerful lows from this sub and haven’t have any complaints with its loudness even though the boat is more open. Cool appearance too. Lots of colors to choose from and each them made the sub better looking.
Best marine sub for the buck I’ve ever owned. It looks really just great and the bass coming from it is amazing for the price. Great power coming from the sub. Seems durable too like my old JL Audio sub before.
