Hey guys,

I am starting to look into upgrading from the Nakamichi system in my 98 GS400. I have a double din in mind, but am a complete noob when it comes to electronics and wiring. I just wanted to know the following so that the installer doesn't start quoting me extra for things I don't need:
- Do I absolutely need to get new door speakers and a 4-channel amp or can I just keep oem speakers and only upgrade the double din?
- Does the amp need to be bypassed? How?
- Does it need a harness? What kind?

I also currently have a 12" JL W6 sub powered by a JL 500/1 amp installed. The OEM sub in the deck blew out a long time ago and does not work anymore. Also, one of my rear doors cannot be opened, so I don't think I can even upgrade speakers.

Thank you!

Anyone able to chime in? I was reading through the threads in the 2GS forum, but kept getting confused by people saying you're supposed to do it one way and then someone else chiming in saying no it has to be done a second way.
