    That's basically the question. I've run some wire through the walls and attic to speakers located elsewhere around the house. Now, I have 4 speakers that I need to have plug into a 4-pr wall plate (banana) and I need to connect the wire to the "solderless banana plugs" that I purchased.

    I looked at them, and it seems as though I could fold the ends of the wire in half, solder those ends together to provide a nice solid contact, then solder them into the cavities of the posts of the banana connectors.

    To clarify, take a look at these photos:

    In this photo you can see how I've folded the wire over in preperation for the soldering:

    Two views of all four sets of wiring connectors.

    Basically, I'll be soldering these while they're off the plate, then I'll plug them into the plate once I figure out which set of wires is which speaker :o

    Soldering is the best connection method. Gas tight unlike crimping, and the most reliable connection if done properly.

    this is assuming your not a crappy solderer (sp)?

    Tonight I was messing around with one of the banana connectors and the solder at work, and it didn't go so well. Basically, trying to solder the wire to the cavity would take a huge amount of solder, would require heating the entire connector to the temp of the iron which would harm the plastic and possibly start to melt it, and be a shitload of effort.

    I'm simply going to tin the end of the wire, screw down the connector until it's nice and tight, and solder that down so that it'll be nice and tight, then once it's cooled I'm going to cover the entire assembly with heatshrink tubing to protect the connection from dust.

    I don't suppose this would get too terribly hot and cause a fire hazard?

    Yeah, it's got a rosin core.

    i would try to tin the wire then tin the inside of the plug then stick in the wire and add a little bit of solder you dont ahve to fil the hold and the hotter iron you can find the better you will metl eh solder quikcer and put less heat into the plastic thingyi am asuming you talking about the black thing but can you solder it withough that thing on there and heat shrink is also a good idea

    well the only problem with soldering them without it being on the main assembly is that I then have to screw them in, and doing one is fine, but then you run into a problem with the other.

    Hopefully the local electronics place will have 1" wide heatshrink, or some heatshrink "tape" so that I can have the installation look clean.

    And I'll try using the soldering gun, I just didn't want to damage the wire in any way, and the soldering gun is pretty damn powerful...that, and I'm not as precise with it as I am with an iron.

    home depot has heat shrink

    i got a huge bag of it at a car show for 5 bucks i have unlimited heatshrink

    Yep, got a ton of heatshrink in white so that I can mark where the wires go
