I recently added the new Icom M504 VHF to my boat. What an amazing unit. It has a loud hailer and automatic Foghorn build in, along with DSC in/out. Great unit ! Its linked to my Garmin 182C.
The Hailer speaker is on the hardtop. This thing gets very loud if you want it to. Trust me, hear the Foghorn tones, and shout something thru the Hailer, and you'll want one of these.
Then I finished mounting my kicker controls. Its located very convienient to the captains chair, yet out of the way most of the time:
