What is the best way to install these ? I have custom kickpods built to the door of my SUV/Montero. Right now i have HD62 set by CDT but am thinking about going to the Perfects for the powerfull sound and bright tweeter. Right now i have my tweeter on the door by the pillar and the mids are on the lower part of the door by my feet. Do these sound good off axis and if so what Crossover settings work best ? 12db or 18db crossed over at 80hz-100hz ? Im also gonna be adding the infinity 652i set for my rearfill and run it off my HU power. Either the 9833 or 9813. Any help is appreciated. Thanks
