Hi all! After posting this thread in the Placement Suggestion forum a month ago, I finally finished up installing the rear TMG heads on my Highlander today. Let me know what you think. Suggestions/concerns welcomed! I also installed a simple kill switch around the center dash near the shifter and an auxiliary ignition-on fuse box under the dash by the passenger foot well. In addition to the TMG, R3, and a small underseat powered subwoofer, I also plan to add a dashcam and some interior footwell lights. Instead of adding a handful of fusetaps for everything, I figured this would be a "simpler" option. I'm gonna try and find a generic Toyota LED toggle switch to replace the switch, and I'll probably move the CPU to a more concealed location. I leveled the TMG heads as best I could, but I may need to adjust them. Before I do that, I want to get them tested as is and then I'll decide if changes neeed to be made. With the BF sale, I'm tempted to get a 4th head for the front and maybe a 3rd head for the back. Do you think that's overkill? Anyways, here's some pics.
