1990 300SE rear seat removal/radio question
 

hello.
i am trying to replace the radio in my '90 300SE and from what i've been reading i am going to have to by-pass the amps behind the back seat. i would like to know if this is indeed what i have to do and if so, how to remove the back of the back seat in order to access the amps.
thank you in advance.
