Compare the BOSS Audio 820BRGB and 611UAB marine receivers. Find out which in-dash unit fits your boat's dash and audio needs.
Quick answer
Choose the 820BRGB if you have a True Double-DIN opening and want multicolor illumination and a wireless remote. Choose the 611UAB if your dash only fits a Single-DIN chassis and you prefer a simpler, lower-cost setup.
Why chassis size matters first
The most important difference between these two marine receivers is the physical size. The 820BRGB is a True Double-DIN unit, meaning it needs a 4-inch tall opening. The 611UAB is a Single-DIN unit that fits a standard 2-inch tall slot. Measure your boat's dash opening before deciding; installing the wrong size requires an adapter kit or dash modification.
Power output and feature trade-offs
The 820BRGB delivers 60 Watts x 4 channels, giving you more headroom for driving larger speakers. The 611UAB provides 50 Watts x 4 channels, which is still sufficient for most marine speaker pairs but may clip earlier at high volume. The 820BRGB also adds multicolor illumination and a wireless remote control, features absent on the 611UAB. If you want to customize the look of your dash and control the receiver from anywhere on the boat, the 820BRGB is the better choice. If you just need reliable Bluetooth audio and AM/FM without extra flash, the 611UAB keeps things simple.
