Clueless about connectors

[mxlope2]

Hello. This is new to me, so I hope someone can help me out. I just bought a new house and it's pre-wired for surround sound. Can anyone tell me how I can terminate the sub wires? There's two cables a coaxial cable and another cable that has four (green, black, red, & white) wires in it. I don't know what type of connectors to put on either end. HELP! This is foreign territory to me. Any help is appreciated. Thank You

Is it a "f-type" coaxial or an RCA. If it is F-type its for Cable TV, If its rca then its either for a subwoofer or video to a projector. The green black white and red are for speakers, prollaby the rear channels. buy a cheap digital multimeter (~$10 at walmart)and do a continuity check between one wall connection and another to see where each wire terminates, and that's how figure out +/- for L/R speakers. you should give some more details about any other connectors in the house. As for terminations use what works best for the speakers, I go with bare wire.

It's an RCA.

The blank wall plate over the two wires is labeled Subwoofer.

The in-ceiling speakers are already installed. These wires are all labeled sub on both (the wall & home theater wall plate) ends.

Sounds like the speaker terminals are meant for line-level input, and the RCA is used for an interconnect between the receiver and the sub.

If this is the case check the back of your receiver for a RCA sub-woofer out. Use a little RCA jumper and hook it up from the receiver to the HT RCA plate, this should then run to the second set of plates in the wall where the original owners sub used to be. Use a second RCA jumper from the wall plate to the RCA inputs on your Sub.

I think what you meant to say was that the four colored wires are for a speaker-level input to a subwoofer amp, not line-level as that would be what the RCA wire is for.

So, depending on the kind of sub and amplifier setup you have you would either connect the subwo oferRCA preamp or LFE output from your receiver to the wall plate as was mentioned, or you could also connect the four bare colored wires to the Left and Right channel output of your receiver and then connect that to your subwoofer's amplifier. This is usually done with a 2.1 setup where the receiver or audio source is not multi-channel, so the subwoofer will take the audio from both channels, combine it, and then play only the bass frequencies.

But be sure to read up about what kind of subwoofer you have before making these connections.
