Hello all AVS users. I want to start off my first post by asking... Is there a way to convert a speaker wire (pos+/Neg-) to a RCA plug without the need of soldering?

I have the Logitech z2300 system from which I thought about upgrading its disappointing satellites into some bookshelf speakers for the extra boost in sound quality. As stated from above, my only nag is that the amplifier on the z2300 sub uses RCA jacks instead of the standardized speaker wire inputs.

What do I need to do?

Cut an RCA cable in half, expose the wires (on the cut end). Twist the ends of the wires to a piece of normal speaker cable. Insulate with electrical tape. Note that the RCA cable will be coax. Unwrap the shield strands from around the center conductor and twist them together to make negative, use the center as positive. Should be pretty straightforward.

Try a search for "solderless RCA connector" - Radio Shack carries them, many places online as well. You either crimp the wire to the connectors, or they have set screws that crimp the wires.

I don't want to stop you from trying this, but be aware that it might not work as well as you hope:
* the amp may apply EQ to the signal to work specifically with the z2300 satellites, which could make other speakers sound odd
* you may need to pick replacements that are similar in impedance to the z2300 satellites or the speakers might not play loud enough or could even damage the z2300 electronics

sometimes RCA cords.. the wires are too small, and even too weak, to be useful.

it might be quicker and easier to get a pre-made rca cord with cut off ends.
these are like speaker wire, not the coax type.

i have split into coax wire as small as usb cords.. they get tiny and arent worth the hassle because they are fragile.

i dont know the size of the wires with that speaker set.. but if its the same thickness as a keyboard cord (or mouse cord) then its probably safe and wont cause much frustration.

Thanks for the replies guys. I did some research before starting this thread. The z2300 satellites are rated as 8 Ohms of impedance.

I just picked up some Mission 73 bookshelf speakers for a good deal, and am hoping that they will work properly with the the z2300 amp. The speakers (mission's) have a recommended wattage of 20w-50w. The z2300 amp should put out about 40w per channel.

So, would you guys still advise me to continue with the project? If all else fails, I'll consider picking up a 25w or 40w amplifier off of online or something.

Sounds like it could work. You could always get something like this and chop it up to try, without damaging the z2300 cables:
