I've researched this a bit and from what I've read it's not (easily) possible to retrofit the Alpine kit if you have the Hi-Fi system, as the Alpine kit is designed to replace the standard system.

I've also read that the Alpine is not as good as HK.

My impression is that it's only a little bit better than Hi-Fi, so in your situation, I think you're better off either leaving it alone or taking it to a dedicated audio shop for some serious upgrades.

But this is all based on hear-say, so...

Good luck!
