Installing Android head, need suggestions on speakers/amp

Hello guys I have my eyes on
KLYDE 8" 4G Wifi Octa core Android 8.0 4GB 32GM ROM from AliExpress
My brand new prius stock stereo w/o JBL amp has blown twice and doing my research I have learned that the stereo itself has a built-in amplifier.
The new android unit I am looking to invest has a built-in amplifier but the problem is if it ever goes out, will I be able to use a external amplifier? Or just go for a external Amplifier?
Need some speaker advice in which to get
I listen to Classical, symphony, dub and some rap if that matters in getting the good quality of sound.
