Thanks for posting. Changing the speakers is the number one thing on my list.
In addition to the helpful post, any other tips/tricks to removing the door panels? I like the idea of just leaving the window switches alone. Seems like there was also plenty of room for the amplifier? Lastly, if you had to split the improvement between the speakers and the amp, what would you say? E.g., better sound is 50% amp, 50% speakers? Thanks.
For others, I had switched the head units on my Elise, and my first Evora (2012 NA IPS). It seems like the Alpine's are generally plug-and-play across most models, but you can find all of the manuals on line, and at the back they show all the connections, so you can see if they P&P exactly, or if not, which wire goes to which.
