This is quite high on my list of improvements to my Base. The Base car I drove had a terrible stereo system in it, much worse than the stock Bose system in my RSX-s. I am not an audiophile by any means, but the stock GT stereo definitely needs help. I plan on replacing all 4 speakers as well run by a 4 ch amp and a subwoofer as well. I look forward to your amp install on the '13 to help me when mine arrives (should be this week!). Thanks for taking the time to do this write-up!
