I used a different company but I totally agree with you on these radio conversions over the factory original AM/FM radios. I bought an original and then realized that I needed to spend a pile of cash for a multi plex to run four speakers, so I sold it and bought one of these. With these conversions you can run four speakers and keep everything looking stock and still have quality sound. If your the type of guy or gal that likes to have everything looking stock and enjoy driving your car whether it be a lot or only on limited sunny days this is for you. I enjoy mine and would recommend it to anyone. You can always take your stock AM/FM radios out and put them way for safe keeping and reinstall it later if you would ever want to. I have mine hooked up with a toggle switch so that I can switch it over to run an MP3 player and it works great.
