I'm looking to add an aftermarket amp and subwoofer to the 2007 Rav4 with the JBL audio system. I have an LOC Line Out Converter I'm using to then connect RCA's to the aftermarket amp for the sound. I tried splicing in to the rear driverside speaker in doorkick panel but to no success with sound. I believe the wires are black and yellow I need to tap in to but there are multiple black and yellow wires. Does anyone know which wires I need to tap in to in this location of the vehicle? I know the amp is in the rear right of the suv behind the panel but it's just a pain to take out to access. I'm just looking for an easy way to tap in to speakers with the LOC if anyone knows, thanks.
