Compact Marine Receiver

The WUQ GR-306 is a compact marine receiver built for boats, ATVs, UTVs, golf carts and spa hot tubs. It delivers 40 watts across four channels and includes Bluetooth streaming, USB playback, AUX input and AM/FM radio. The unit carries an IPX6 water-resistant rating and a salt-fog rating of 66 for durability in wet environments. No CD or DVD mechanism is fitted.

Installation Fit

The stereo uses a 5.11 inch cutout diameter and a 6.1 inch top-plate diameter with only 1.1 inches of mounting depth behind the plate. This shallow profile frees dash space on small fishing boats, cuddy cabins, personal watercraft and tight RV consoles. Bluetooth lets you control music and apps like Spotify or Pandora wirelessly from a paired smartphone. USB charging is available for connected devices.

Upgrade Path

The GR-306 replaces older single-DIN marine decks that lack Bluetooth or have deeper chassis requirements. It is a direct fit for cutouts sized to the 5.11 inch specification and adds wireless streaming without rewiring speaker loops. Builders needing a CD player, multi-zone output or a larger display will need a different model. The jump is worthwhile when shallow depth and wireless audio are the priority.

Questions about this item

What is the maximum amplifier power before the IPX6 seal is stressed during long sessions?

The receiver delivers 40 W × 4 into 4 Ω speakers; sustained output at that level is within the thermal design of the IPX6-rated chassis.

How warm does the aluminium chassis get and will the fan noise rise after hours of continuous play?

The solid aluminium chassis acts as the heatsink and the unit has no fan, so temperature rises silently and stays within the IPX6 rating during all-day use.

What size dashboard cut-out and mounting depth must already exist for the GR-306 to fit?

A 5.11 inch diameter cut-out and at least 1.1 inch of clear depth behind the panel are required for the 6.1 inch top plate to sit flush.
