Took a bunch of pics today on how to remove the door panel and where to wire-in the capacitor. I will post a guide soon after I figure out how best to describe the exact procedure...don't want to ruin anyone's day with incorrect instructions...

Wiring the capacitors directly out of the amp is a really good idea. Quite honestly, I didn't think of doing it this way. Intriguing idea. Somebody posted the stereo diagram at one point and it looks like the pins out of the amp as marked on the diagram are 7 and 8. A little problem looks to be that there are two pins that are labeled 7 and two that are 8. So one would have to find the wires that are Black/Pink and Black/Blue and wire in the capacitors there.

I am going to have a look at the amp and see if this is a possibility. I have read that it is in the passenger footwell area behind a panel somewhere...
