E90 Base Speakers Upgrade

I want to upgrade my e90 base audio system (CCC). First i want to upgrade the 4 midrange speakers. After that i will add an amp for the 4 midrange speakers and last the underseat subs with another amp.

Which of these should i get?

Not a familiar brand but why get coaxes at least for the front
when the BMW tweeter pods/holders are pretty cheap.

Agree with ctuna, may as well get components.

Having said that, I would do the amp first, the base speakers sound surprisingly OK when driven with a decent amp.

No point putting better speakers running of the stock head unit, they will probably sound worse than you have now.

I would consider a 4 channel amp.

Run the subs off the rear channels and the mids off the front channels.
Run the rear speakers off the head unit.

It is a really easy, quick install as well and makes a huge difference.
