I had a set of SeaWorthy speakers with a CD receiver mounted by an aftermarket guy in my Triton 18X3 Pro. They are mounted up under the consoles, so a lot of the sound is deflected by the undersides of those pieces of fiberglass. Treble was almost non-existent. I purchased a higher powered digital media only FM receiver by Nakamichi, and paired it with these Poly-Planar models and could not be happier. Perfect drop in physical replacement to the existing 6" SeaWorthy speakers, but significantly better sound and frequency response. You don't need 100W/CH in a marine stereo to get decent sound fidelity. These are keepers! WalMart had the best price, and we got them in just a few days...hard combo to beat.
