I have a question somewhat related to this. I have the RF in my 2003 and I think it sounds terrible. Also, I want to update as well. So, I'd like to replace the RF double din radio with a double din touchscreen that has Android Auto and Apple Car Play. My question is, I had a car MANY years ago that had a factory amp in it, separate from the factory radio. And it was a nightmare to bypass that amp. Is there a relatively easy way to remove the RF radio and RF amp and then use a new radio and use the new radio's internal amp to run the speakers in the door?
