I have a clarion dxz545mp stereo, with an alpine amp..when my car is cold I get an "amp guard" message..as soon as my car warms up everything functions..How can I fix this problem
, the message you are getting is "amp guard". This is the mesage it will
display when a short in a speaker wire or speaker with low impedence is
hooked to the internal amp and sends it into protect mode, shutting
down the amplifier section while the rest of the unit continues to work.
