[QUOTE="keep_hope_alive, post: 8658210, member: 576029"] I used the EQ features within the JL Audio VX1000/5i amplifier to correct for the abysmal equalization within the stock head unit. I went back to the original Sport head unit and have achieved a very good sounding result, the best one yet with the original head unit. The before and after curves are shown: [IMG]http:////applications/core/interface/imageproxy/imageproxy.php?img=http://i38.photobucket.com/albums/e128/phat_funky_beats/2014%2520Accord%2520Sport/20180620_200700.jpg&key=cb6dfb4138dcad7e225b1b2393f4f2bb39763f717bdc0de9132b1cb4dd5fba08[/IMG] Example of what the EQ looks like. Essentially, I used a shelving EQ to lower the mids and highs to help flatten the low end. Then I adjusted from there, visually, and fairly quickly. Better results are possible.
