No, not unless you use a switch. Then you'll have the problem of remembering to put the switch in the right position and the risk of damaging the VHF or stereo by running it with no speakers connected.

If your stereo has an auxilliary input, you could connect the external speaker output of the VHF to the input on the stereo but you would have to keep the volume on the VHF pretty low to avoid overloading the stereo.

Why not just install a dedicated external speaker on your VHF?

Since a number of people keep mentioning it, you can buy speaker-level (like your vhf outputs) to line-level (RCA inputs) converters for $5-10. This would allow you to plug into your aux input on your stereo safely.

Unfortunately, it would not give you what everyone REALLY wants which is a stereo that "overlays" the vhf input on top of your other source... You'd need a little better integration.

Hey Flot Thanks for the input no pun intended ( well maybe a little) but I will check for that input on my stereo, also did not think of a surface mount was thinking of flush mount which I did not want to cut another hole.
Thanks very much Hoejef

I do not believe that is a good idea, but you can connect the low level output of a VHF to an AUX input port on the stereo. I am surprised nobody has incorporated input sensitive AUX inputs on Marine stereos yet, perfect for a VHF solution. No even Poly-Planar with their IMR-4 module consider this as an option. So with this option you have to switch to the AUX port to listen to the VHF, you can't listen to the stereo and have it mute when the VHF comes on.

I did find however a Marine Stereo that has added a Marine VHF and weather receiver. The GR100 has AM/FM, 55 channel VHF and weather receiver. I do not know how it works, but I think you still can only listen to one source at a time.

One possible solution if you have a separate power amplifier would be to use a small 2 channel low level audio mixer to combine the low level outputs of the VHF radio and stereo into the power amplifier. You could only do this on one channel. You would need a level control on the small mixer to set the VHF audio level. You might be able to use an RCA Y-cable to combine the low level audio outputs of the stereo and VHF into the input of the amplifier on one channel, than you would need to use the balance control on the stereo to make up for any level loss on that channel, not hard to do.

Here you go - for anyone who wants to connect their VHF to their stereo... speaker level to line level (RCA) converters, this way you'd run your VHF into your stereo's AUX in.

Most stereo's today have either an Ipod or Aux input jack which will either be a 1/8" or 3/32" stereo plug either on the front or back of your radio. MOST of the time, this jack will take BOTH a line level (no power) or speaker level (with power but only a small amount like what comes out of small mp3 players). Just plug in the VHF output which is ussualy 5 watts, and it will work fine. Your radio will play it just fine. I've been doing this for years with many different stereos, never had a problem. Just put the stereo in ipod or aux, and whalla.

Save yourself a lot of trouble and get an external VHF speaker.

If you plug your VHF into your stereo - which you can do by the way - will you REALLY use it? Really? Come on now. Can you truly say you would use it??

OR would you just crank the music and forget all about the VHF? Do your guests, who may not be boat people, want to hear music or someone calling a marina or asking for a radio check.

Do yourself a favor. Forget about using your stereo for anything but music. VHF radio is for listening to people call marinas, and the stereo is for some good tunes. Never should the two ever cross paths

I have a loudspeaker / hailer connected to my VHF (Icom M504), and I also have the ext speaker output on the VHF connected to the stereo. The icom lets me TX the sound on either. I use them both about the same amout. The nice thing about the stereo use is, there are speakers everywhere, in the cabin, outside in the middle of the boat. So you don't have to crank it up very loud to be herd, anywhere on the boat. Unlike when I put it on my hailer loudspeaker, it's just too loud to make it herd in the cabin.

The VHF is used for more than hailing a dock. How about fishing offshore, trolling and finding fish with a few buddy boats.... ;-)
