Can this connect to speaker output for rear speakers?

The input is for a line level out from a sound source BEFORE an amplifier. IF you are looking for something to use on the speaker side of an amplifier this WILL NOT WORK.

I tried using this for a bose bass 500 subwoofer which has a 3.5mm audio plug at each end, but it didn't work. bose may use a special signal. ideas?

This is designed for a line out from the source to the amp. It uses RCA jacks. If you are using between amp and speakers, that is an amplified signal and most likely overdriving this unit. Just my thoughts. Hope this helps.

Is it possible to get replacement antennas for the RT5066? Mine are missing.

I am not sure but I don't see why not. You can use other antenna that fits the thread.

Can you buy an extra receiver? I need 1 transmitter and 2 receivers.

The product we don't sell separately comes in a complete set.
