I wanted to share my upgrade of my front door speakers using Infinity Kappa 62.11i. These are one of the few aftermarket speakers that I could find that have 2Ω impedance which matches the factory specification. This was important to get as close as possible to retain efficiency from the factory amps. I noticed others using the same speaker mentioned that they ended up reusing the factory mounts and cutting out the oem speaker. I wanted to retain the original speakers so I decide to create a 3D printed version. Below are a few pictures of the mount and connector. Bottom with felt glued on. Speaker Connector. After having just one of the upgraded speakers installed I was able to compare it between the factory speaker and my observations are that the Infinity made a huge difference in clarity of the upper and mid frequencies while removing the boomy one note sound of the oem, especially at higher volume. On the bottom end it really did not add any additional bass but tightened up what was there. I wasn't expecting much as you can only get so much bass out of a 6 1/2" driver. I also noticed I could increase the volume beyond 7 without distortion. This was definitely worth the time and minimal expense (about $130 for the speakers, 3D filament and misc materials).
