No, because in a pure amplifier the radio part is always missing.
Depends on what your definition of "receiver" is, but most of the time - to the amplifier. Consider: if the receiver is some form of a device that receives some signal, and then decodes it to audio, then the receiver will hook into the amplifier, which in turn will drive the speakers (so the speakers go to the amplifier) if, on the other hand, the receiver is a part of a wireless connection between the amplifier and speaker, then it really serves the role of a cable, so in essence you're again connecting the speakers to an amplifier (only using the receiver as an intermediary) You would have to specify your case.

Is this sentence supposed to be question? Any superheterodyne receiver will have an IF amplifier. It doesn't matter whether TV or radio.
ideally "line out" on the receiver to "audio in" on the amplifier, left and right... If there isn't a "line out" use the the "audio out" but keep the volume on the receiver relatively low to prevent overdriving the inputs on the amplifier.

Speaker cable is used to connect the speaker outputs on audio devices such as a receiver or amplifier to the inputs on the speaker(s).
As a frequency receiver
The receiver is the amplifier for all the speakers, except usually the sub, which is most common with its own amplifier.

To connect two home receivers with a 2.1 hi-fi amplifier and subwoofer, first, designate one receiver as the primary source. Connect the audio output of the primary receiver to the input of the 2.1 amplifier using RCA cables. Then, connect the subwoofer to the amplifier's dedicated sub output. For the second receiver, use its audio output to connect to the primary receiver's audio input if needed, or use a switch to alternate between the two receivers.

To connect your receiver to your amplifier, first, locate the appropriate audio output ports on your receiver, typically labeled as "Pre-Out" or "Zone Out." Use RCA cables to connect these outputs to the corresponding inputs on your amplifier. Ensure that you match the left and right channels correctly—left to left and right to right. Finally, power on both devices and adjust the settings as needed for optimal sound.
