hi. i just bought a 93 es300. i have a question. i blown the speakers on the dashboard and i went and bought some speakers. i took the old ones but the new ones dont fit. they are aftermarket ones. now the question. how hard is to take the dashboard off from 1-10? a friend of mine knows how to take the windshield off but he is charging me too much and he doesnt want to be responsible for cracking it. should i take them to a audio shop to have them install for me? another 2 questions. are speakers on the front door panel? and where is the OEM amp?
