First, I'm not a Pyle tech. But back in the day I used to be an audio freak (1970's 4 channel all-the-way!)
* I tried to get the exact specs on your receiver but I suspect it's a non-amplified output. RCA jacks almost never have a high level output. (yes, the old 1940-60's used RCA jacks for speaker high level output. But you have a late model receiver.) Most likely you need a separate amp to power the sub woofer (unless it has it's own power amps.) You may still use another audio amplifier if you have a spare (mono or stereo won't mater as you only use one channel) but be aware that low frequency use way more power than normal frequencies (600 to 3KHz) The low end (50 to 300 Hz) will burn out any speaker and amp as the lower the frequency it's like hooking up a car battery directly to the speaker! If you have an old style vinyl record player that's playing a warped record. watch the speaker flap around to the wave of the record. Need to turn on the 50 Hz cancel out button to prevent speaker blowout!
* This link is still for a powered woofer. It looks like the same PD3000 receiver as yours though I can't be sure:

* This is an external "Powered" sub woofer (powered amp and additional cross over "filter" to extract just the lower frequencies. The following you tube link is a detailed example of how this type of system works:

RCA or Phono type plugs only have a single pin plus ground and so one plug and lead assembly is needed for each channel..
It is important to match the output of the tuner to the input of the amplifier. This is easy if the amp has a dedicated tuner input but if it hasn't it is best to study the instructions, though at a push the line-in or auxiliary input might provide satisfactory reproduction.
I had a brief look at the spec and it says the speaker outputs are banana sockets/plugs.
Once the four speakers are connected, or two with the fader control adjusted, it should produce good sound and if it does the next stage will be to connect the subwoofer with RCA plugs into the dedicated outputs.
I suggest you reread the manual.
It will work but the sound quality will be quite bad as the audio input is around 600 ohms and you have 8 ohms from the speaker output, you can build a crossover circuit quite easily for a few dollars
Probably pretty easy. On back of TV see if there are RCA AUDIO OUT plugs. One likely is red, one white. Run a RCA cable from those to your AUDIO/AUX IN connectors on the receiver ( Be sure to turn off the internal speakers on the TV. More info here:

Good luck!
