I have found MP3Gain to do a decent job at fixing the problem that recording levels are all over the map. It does so by adjusting the block scaling factors in the MP3 file, without re-encoding, so there's no quality loss. I've been using MP3Gain to adjust my files to a "86 dB" level.

Interesting... Does it work with AAC files too, or just MP3?

Apparently there is now a version that works with AAC:

Quick note - alternative for speakers I just stumbled across:
Polk MM651

They're 2.7 ohm (so slightly higher impedence), but they have a major advantage in that they use neodymium magnets like the stock speakers, leading to much lighter speakers. Amazon has them for about $100.

Oh, neat, I was just looking at the documentation on them, they have a pretty nice external passive crossover (most coaxials just have a cheap capacitor on the tweeter).

This information can be used to remove the two pieces on the door so you can get to the screws underneath and ultimately remove the door panel. I followed the directions in the INT manual. You really need a thin tool for the bottom piece. One you get the two pieces off, then disconnect the wiring connector for the door lock / power window. Then remove the two screws.

Any possibility you might scan those pages and post them for us? :roll:

Rather than just looking at a few pages, for $19.99, you can get a one day subscription from Nissan and download and save all the pdf files for the service manual at the link below.

Definitely worth it...
