Yes, I am seriously thinking about switching from blinder m27 to LI quad for my Infiniti M35. Hopefully, next month. I have posted my car's picture on "advice on placement" so your input on where I should mount my rear heads is needed. I will do the install myself after a crappy experience with my blinder's install from it's authorized installer. I will need help on how to tap power from the fuse box and if possible I need illustrations. Thanks!
