After multiple warranty replacements on my BavSound under seat Ghost Kit, I’ve decided to go a different route. One of the best audio shops in my half of the country has recommended the Focal ISUB BMW 4 drop ins as a better plug and play option. This is the 4 ohm version designed for use with the factory HK amp as opposed to the 2 ohm version designed for aftermarket amps.
Has anyone tried these?

They’re $499/each at all the reputable companies stateside, but I’m seeing them for less than half that amount on eBay from reputable car audio sellers, shipping from Germany. I know they’re made in France, but that alone can’t account for such a difference in price, can it?
