For those of you who have this done, I have some questions. First of all did you do this yourself? if so how hard was it? what did you wire into for power? how about ground? where abouts did you install the on/off switch? was this hard as well? in my old car, i just taped them under the dash and wired into my remote start thing and just taped an on/off switch under the dash I want to do it properly and if it seems to complicated (I don't want to mess anything up) I'm just going to go to a shop here and get them to wire them in. Thanks!
