Default VHF extension speaker...no worky?

I am embarrassed to admit I don't know squat about ohms and such. I just installed my new Standard CPV350, replacing a Garmin and an Icom VHF. It has an ext. speaker wire which consists of a white wire and a shield wire. My existing ext. speaker has a plug, which plugged nicely into my old Icom. So I thought heck, I'll just snip off the plug and hard wire it to these new wires. Doesn't work.....in any configuration.

Now, after having looked at the specs, it appears the radio requires an 8 ohm speaker, such as one of Standard amplified speakers. I couldn't find any writing on the old speaker, but after looking at others on the 'net that look like it, I think it's a 4 ohm speaker.

Is this my problem, a 4 ohm as opposed to an 8 ohm? I don't mind buying the new speaker if this is indeed the problem.

Thanks! This new Standard combo VHF/Chartplotter appears to be a VERY nice unit. Beautiful screen and a whole bunch of both GPS and VHF features like separate DSC, hailer and I got one of those new C-map Max chips.

It appears you have done things correctly.The diference between4 and 8 ohms would be the volume in most cases.It might just be the new rig,do you have a earphone for a portable radio you could attach the wires to to check the new radio's output with.Then again.the new rig might have a switch position on the new set for the external speaker?

IT might be that the external speaker is used for the hailer function????

When it didn't work, I figured it might have an on/off in the menus somewhere, but couldn't find it. I will do as you suggested with the earphone. I thought it would've at least worked, no matter the ohm rating......at least from what I remember from my old home stereos and various assortments of speakers!

Thanks for the help, I'll do further testing tomorrow before I call Standard!

Nope, not the hailer. I looked specifically in the manual for which set of wires to use just for the speaker. The hailer has a red wire, speaker has a white one. At least I had that part right.....hopefully they have the manual correct too! Good idea though, because both sets are right next to each other.

Well, I couldn't stand it and walked down to the boat at about 10:30 this evening.......lo and behold there was a setting for external speaker, amplified or no. BINGO!!!! This setting was about 5 levels down in the setup!!! Works just fine, thanks for all the help. I just love a happy ending. Now to go down in daylight and make all my connections seaworthy.
