Ok, Now I need some help... I am planning on mounting the amp under the passenger seat and trying to figure out what is the best route for the 8 gauge power lead through the fire wall? I thought about running it down the engine bay and up through the shifter... Which is how I ran the AEM wideband.... But I thought I read where the WB needs to be isolated from other power sources.... Any audio pro's out there that can give some guidance?
