Been taking our brand new sx210 out for a few weeks now and really loving the ride; great fun. But you just can’t hear the stereo.
What upgrades do others recommend to make it so tge captain can actually hear the tunes :)

Not overly familiar with how they equipped the 2020 sx210. From the literature, it looks like you have 4 speakers, but unsure of the brand and what head unit you have.

Most head units only put out around 15-20w RMS. I would suggest adding an amp and seeing if that solves your problem, or if the issue is the lack of fidelity from the speakers, requiring a larger investment.

Look up the speakers to see what they are rated for power wise and confirming if they are 4ohm. (The back of the speakers should either be stamped or have a sticker indicating the model number and potentially the specs). Then match to an amp. Also ask yourself if you may want a sub down the line. That way you can by 1 amp now (5 channel) vs potentially two down the line.

Four new speakers and an amp is usually enough to hear underway. I'd recommend adding two more speakers to center of boat.

Good morning, and welcome. I have the same boat, therefore had the same problem unfortunately. I upgraded the speakers 2 years ago and added a subwoofer under the seat. we can now hear at all speeds. I had the stock speakers replaced with Alpine r-65s’s. Had a JL sub installed in a marine box under the seat behind the helm. JL amp installed on the backside of the dash. worked out very well.
