Just got my '02 Accord Coupe yesterday! I'm thrilled with every aspect of this car with one exception: audio system. That's no surprise, of course. To fix it I just ordered an Alpine CDA9847 to which I will be connecting my SkyFi via the aux input. I have a question about this, though.

I had a nearly identical setup on my last car (CDA9807). If I was dumb enough to leave everything powered on when I placed the SkyFi in its cradle it would cause a voltage spike and the speakers would "pop" really badly. I only did it a couple of times but I completely trashed the tweeters. I've learned to be more careful but I would like to make it idiot proof so that I don't do the same thing to another system. Any ideas? Is there anything I can put between the cradle and the head unit that will capture that power surge? I'd appreciate your suggestions.
