I have a is-c 250 2010 and the amplifier stopped working, so Lexus put in a new one ,and that works, but not all the time. I read that I should take it out off the side well and place it in the boot ,which I did and hey presto it’s now working again. So what’s the problem ? and how can I (Lexus)fix it in a more permanent position ,and can you buy extension leads.
