The speakers with an amp is, imho, the best option for a best cost/performance ratio. I mentioned this setup in my original post above, although to be fair the speakers listed are a step down and is not a large cost savings.
The speakers don't require any fitting/ cuts, but you will need a half inch spacer to fit the magnet. I'm sure you would be happy with the setup.
