Speaker upgrade throughout.

So I ordered 4 JBL Stage 602 speakers for my 2002 landcruiser with nav. I was thinking what subwoofer to get that has good base but doesn’t require that much modifications to the car. Also would I have to change the amplifier (ps. I don’t want to).
Lastly are there any Bluetooth modules can I can get for the landcruiser, that doesn’t break the bank, so I can play the songs via Bluetooth through the speakers.

USA Spec too.

I have a Vais, I think USA Spec may be better though, at least from my research.

What is Vias?

Also I’m new to all of this, my speakers blew out a couple of mo the back and I got time to fix it.
