Upgrades to VY Calais system?

[chargedvx6]

I have a set of Alpine type S speakers from my old car and am pondering on fitting them to the Calais. Thing is the stock system on the Calais is surprisingly strong and clear with some small subs included so I'm unsure if the Alpines will be an upgrade at all.

Anyone having upgraded speakers alone.........worth the effort or not?

the standard 6" speakers are 15w. I assume ur alpines are more like 50w or more.
Adding an amp to run those speakers at their rating would also be advisable.
