I think the components are great, and I've used Alpine speakers many times before because they are always a reliable and great sounding product.
In my opinion, I would always choose Alpine over Vibe, but then I have no experience in using Vibes products. Plus the ones I've shown you are less powerful than the Vibes you have found, but of course the power handling isn't everything...
If you do a quick google search on say 'Alpine or Vibe', alpine always gets a higher vote!
Hope that helped a bit
