just installed 3- 7 inch lcds in my 93 929 ,my factory amp was toast so it rendered my factory deck useless so i went a different way with things.i put the three lcds in one in dash where deck used to be and two on the head rests,i also installed a rockford 4 channel i had kicking around ,i then rewired the speakers to the amp and balanced volume to 70% rear channel i then hooked up my 60 gig ipod video to amp and lcds .now i finally have tunes shame about not having a radio tho for traffic eg..but i can find a tuner for my ipoo
