bulkhead connectors for cockpit speakers

I'm going to be installing some stereo speakers in my cockpit, and I'm trying to figure out how best to run the wire from inside to outside. Rather than run the speaker wire through a hole in the coaming and try to find a way to seal against the jacket of the wire, I thought it would be better to get some kind of waterproof connector. In addition to being more waterproof, this would let me easily take the speakers off or replace them if I wished. The only problem is, I can't find any good connectors. Defender has nothing, and McMaster-Carr only has a few very overpriced mil-spec connectors. Does anyone have any idea what is normally used for this, and where to get them? Thanks!

My speakers are cut in and back wired! Boxes take up too much room!.....Dale

Re: bulkhead connectors for cockpit speakers

I thought about getting the speakers that mount into a hole in the coaming, but I didn't like any of the places they would fit. I'm planning on hanging the box speakers from the pushpit, so they shouldn't take up any useful room. Also, this avoids having a speaker become a structural part of the boat (if you get pooped and you have coaming speakers, you're relying on the speaker cone to keep that water out -- if it doesn't you have two very large holes in your boat).

I've already got the box speakers anyways, so I'm not going to change now. I just hope I don't have to shell out $120 for connectors (that's the cost of the speakers!).

Re: bulkhead connectors for cockpit speakers

The previous owner did this on my boat. There is a 4-way bulkhead connector with a 4-way plug on the speakers. It is a screw-lock type but has no label on it unfortunately.

I tried a quick search at Mouser.com :

Mouser Electronics - Electronic Component Distributor Standard Circular Connectors

Seems to be a bewildering selection available.

I found that the sound from the small West Marine speakers was so bad that I removed them, and now I just turn the cabin speakers up louder.

rm-
Waterproof connectors seem to be as common as hen's teeth. But there are Bulgin brand Buccaneer connectors, made in the UK and sold by a few of the electronics houses in the US.
Buccaneer IP68 Waterproof Electrical Connectors for Data and Power by Bulgin Components

Truly commercial grade water proof connectors. I'd suggest buying some spares when you place the order, rather than trying to track them down again in future.

Re: bulkhead connectors for cockpit speakers

Another connector is the Switchcraft EN3. They are also IP68 waterproof and a little smaller than the smallest Buccaneer 400 series connectors. The standard Buccaneer connectors are about 2.75 inches long. The EN3's are available in the US fromMouser along with the Buccaneer connectors. The EN3 uses a bayonet lock while the Buccaneer is threaded.

Re: bulkhead connectors for cockpit speakers

How about this clam cable deck seal. I have used this to run the Raymarine seatak cable through the bulkhead out to the 125 antannnae on my rear rail. It seals around the cable/ wires. make sure when you drill through the deck/ gelcoat you fill in core to prevent any water intrusion. They make them larger sizes as I have on where my radar able goes from the tower on my stern rail through the stern

Re: bulkhead connectors for cockpit speakers

look for Perko or Gino 2-pin deck connectors. both have integrated rubber caps for the plugs. Perko connector goes for about $15 and I saw Gino on Amazon for about $6
