AtLien here. My sis left me with her 03 when she moved to the land down under. Just starting to do some work on the vehicle, about to change the VTM-4 fluid, as I am pretty sure it has never been done. I just recently installed 4 new door speakers, a JVC single din, and JBL tweeters! I was so happy the speaker grilles just popped off! Thanks Honda! My 08 Mustang speakers are nowhere near as easy to change. What are the limits of the VTM-4 lock? Never used it.
