The round gauge-mount form factor is the primary selling point — position this for customers with helm panels that lack a DIN slot, particularly on older vessels or compact center-console layouts where gauge clusters dominate the dash. Confirm the customer has an 80mm (3.15”) gauge hole available or is willing to cut one. At 862g it’s a lightweight install. The switchable US\/EU tuner makes it a viable option for customers who cruise internationally. Pre-amp outputs allow future amplifier addition if the customer wants to expand the system later.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51003828633636,"sku":"153-MGR300B","price":290.39,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/018b7a15-0ef4-4ac4-9da6-f128a0447819_1.png?v=1783216822","url":"https:\/\/marisolmarine.com\/products\/boss-audio-mgr300b-marine-gauge-stereo-153-mgr300b","provider":"Marisol Marine Company","version":"1.0","type":"link"}
