I would get a DAC(used) with Bluetooth function. Which could upgrade the sound from your CD player.
There’s already jumper cables on the connectors, just a pair of speaker cables + and - both go in the bottoms.

Ill stick with the basics for now just hope these castle 2s are ok ill probably be amazed although the one in the car is a14 speaker meridian and tgats superb

If you want a sound similar to that in your car then get a decent headphone setup. A hifi setup in a room will sound completely different to that in any car, the two are just not comparable.
