Superb 10 speaker upgrade

Hello.

I've read some of the threads here regarding the upgrade, but some don't have working photos, some don't have working links.

I want to change the head unit and I read it's not compatible with the oem amp. So if I'm changing the amp, why not change the speakers also. I have the 10 speaker option.

I found a kit of woofer 16.5 and separate tweeter with a crossover.

Is it ok if I don't connect the mid in the new system and use only the new woof and tweet?

Do I have to use new wires for the speakers or can I disconnect the wires from the oem amp and put them in the new one?

I read the speakers need adapters because the holes are bigger than 16.5 or something. Should I search for universal adapters or?

The speakers are rated 60W nominal, the amp can deliver 70W, but the new head unit can do 45W per channel. Is that a big discrepancy between the unit and speakers?

The reason why I'm asking so many questions is that I don't want to remove the door panel too much, once and good.

Kind thank yous for the help.

Regards
