92ucf10 Posted May 23, 2010 Share Posted May 23, 2010 So over the past few days I've noticed that whenever I turn on my Nakamichi system, something in the trunk rattles and the signal gets choppy. The problem started one time when I had a heavy load in the trunk, but remained after the load was removed. After a couple seconds, it sounds smooth as silk, like it used to. I don't think that it's a debilitating problem, but is it something I should be concerned about now? 92 LS400 Air ride suspension Nakamichi Premium Sound System and CD Changer Does anyone have any thoughts on what it might be? Thanks. Quote Link to comment Share on other sites More sharing options...
dcfish Posted May 23, 2010 Share Posted May 23, 2010 The load probably knocked the CD changer connection/mounting bracket loose. Quote Link to comment Share on other sites More sharing options...
92ucf10 Posted May 24, 2010 Author Share Posted May 24, 2010 The load probably knocked the CD changer connection/mounting bracket loose. That's what I was thinking, but I can still use the CD function. If that was the case, wouldn't the sound system just refuse to pick up the CD changer? I'll check that out.

RDM Posted May 24, 2010 Share Posted May 24, 2010 The Nakamichi amplifier is mounted underneath the CD changer, maybe remove and check it for loose plugs, debris in it, damage, etc. Quote Link to comment Share on other sites More sharing options...
92ucf10 Posted May 24, 2010 Author Share Posted May 24, 2010 The Nakamichi amplifier is mounted underneath the CD changer, maybe remove and check it for loose plugs, debris in it, damage, etc. I'll take a look into that, but how would I get to it? The Lexus service manual only describes standard equipment installation and removal. Have you worked on Nakamichis before? Update: I think that this might be an issue with the power antenna, because the rattle happens only when the radio is turned on and comes from the toolbox area in the trunk, not the amplifier. Does this logic make sense, or am I taking a shot in the dark? Quote Link to comment Share on other sites More sharing options...
dcfish Posted May 24, 2010 Share Posted May 24, 2010 Check into the antenna issue, Could be loose... Quote Link to comment Share on other sites More sharing options...
92ucf10 Posted May 24, 2010 Author Share Posted May 24, 2010 Check into the antenna issue, Could be loose... http://www.lexls.com/tutorials/audio/powerantenna.html Here's where I got the idea. I don't think that it's loose. I think that maybe it just got jammed. Since I can hear the rattle (that is, the motor is trying to extend and retract the power antenna), I don't think that the motor is broken. However, to get to it, I need to get the antenna nut off.
