300zx Z32 rear speaker upgrade

With the parts I already own, from my 2017 Sentra, I am going to install a sound system all around starting with rear speakers.

Does the convertible version has rear speakers?

I know the factory speakers have like a built-in amplifier, do you know if they have a power cable going into each speaker as well to power their own amps? I am replacing them with new speakers and I assume I can just use the stock wiring to the speaker, bypassing the power cable/factory amp with the stock speaker wiring.

So use the purple and yellow wires after the connector. The purple is positive and the yellow negative. You can cut the other wires to the connector so you don't get a short(if you want to pull the amp) or leave everything alone.
