Compare BOSS Audio MR652C component speakers and CH4330 4x10 full-range speakers to find the right fit for your boat's sound system.
Quick Answer
Choose the MR652C component system if you want clearer highs and better staging from a 6.5-inch setup. Choose the CH4330 if you need a simple drop-in full-range speaker for a 4x10 location.
Component vs Full-Range: What Changes on the Water
The MR652C is a 2-way component system. That means the tweeter mounts separately from the woofer, so you can aim it toward the listening position for sharper imaging and more detailed highs. The included 12dB/oct crossover splits the signal cleanly, which helps each driver work in its sweet spot.
The CH4330 is a 3-way full-range speaker. It combines a woofer, a 2-inch midrange, and a 0.5-inch tweeter in one basket. Installation is simpler because there is no separate crossover to wire, but you lose the ability to aim the tweeter independently.
Size and Fit: 6.5-Inch vs 4x10
The MR652C uses a standard 6.5-inch woofer, which is one of the most common sizes in marine audio. That makes it easier to find replacement parts or upgrade later. The CH4330 is a 4x10 oval speaker, a less common size, but it fits factory locations in many boats that were built for 4x10 speakers.
Before you buy, measure your cutout. The CH4330 has a mounting depth of 2.375 inches and a mounting hole of 3.78 inches. If your boat has a 4x10 opening, the CH4330 is a direct fit. If you have a standard 6.5-inch round hole, the MR652C is the one to use.
Trade-Offs at a Glance
- Sound Quality: MR652C: separate tweeter and crossover produce clearer highs and better imaging. CH4330: single-unit design is simpler but less refined.
- Installation Effort: CH4330: wire it and go, no crossover to mount. MR652C: requires mounting the tweeter and crossover separately.
- Fit: MR652C fits standard 6.5-inch round cutouts. CH4330 fits 4x10 oval openings with a mounting depth of 2.375 inches. Measure your existing speaker hole before ordering to avoid returns.
