Do you happen to have the model of the TV? My Samsung only has two digital optical outputs. If your'e plugging in JBLs, you may only have an analogue input which won't work.

first off stock wiring for speakers,and or amp are with minimal wiring.Rewire system for better sound quality,also use noise suppresors if needed.

Yes, a receiver is also needed. The manual is here:

speaker A should two cables running from it plug one end into speaker B a large RCA jack,

Plug the other end into your PC Sound card (speaker out ((( )

then if it's a active systems plug Power converter into A/C port on back of Speaker A

i had to buy a complete amp and replace the old

There was never anything mentioned about the 18 yamaha sub in the hook up process

Are there 4 inputs on the back of the speakers? If so, you either need to hook up all four, or connect the upper and lower inputs to each other. The speakers come with gold plates that connect the upper and lower inputs, but you can just use speaker wire to connect them. At least that is what I did on the used set of speakers I bought when one plate was missing.

The 2 leads that come off the HF driver are different sizes...you should only be able to hook them up one way. Takes the guess work out of it for ya.

Assuming there is nothing wrong with the speaker, hooking up the 2418H HF driver to it should do the trick. However, I blew my HF driver a few months ago and bought a new one, only to blow it immediately. This was because the motherboard of the JBL EON G2 had actually failed and caused the HF driver to fail. Once I replaced the motherboard and the HF driver (again) everything was back to sounding great. Hope that helps.

It should be having onboard sound card, check from Bio's setup whether the Audio is ON. also check in control panel sound and media devices and check the volume maybe it's very very low or on mute. Also try with other speakers
