I have a couple of questions, as I am looking in to replacing the stock component speakers in my 2013 Accord Touring. I'm currently looking at the Polk DB6501's and want to know if I need speaker adapter rings to mount the new speakers. If so, where's the best place to buy them? I'm planning on getting the wire harnesses for the new speakers. Maybe down the road I will add an amp, replace the back speakers and upgrade the subwoofer. Can you offer any suggestions? This is a daily driver, so I don't want to lose any trunk space, by putting a ported/bandpass box in there! I not looking to rattle my neighbors windows, but want good sound! Any suggestions would be greatly appreciated, thanks!
