I had a 23' boat a few years back and put it on a trailer and brought it to Best Buy and had them install it and did an amazing job. Can't go wrong for the money. They used a subwoofer enclosed mounted behind the aft seats and I had a grill cloth frame made, high power amp, the works cockpit and cabin. They had a weekday special with free installation and did it for a couple thousand. Amazed everyone. I even had 2 speakers in an enclosure that you could plug in and put on the bow for parties when out from shore. It was too cool!
