In the process of replacing the dash and door speakers with new 4 ohm. Kenwood KFC-835C 40-Watt 3.5-Inch went in the dash and fit nicely with cover installed. Kenwood KFC-1366S 5-1/4" 2-Way Speakers are going in the doors but have not arrived yet so I can't verify fitment.
After looking at old threads I see they need to be rewired from parallel to "in series" to not harm the OEM radio. Having trouble finding good instructions to complete this. Is this done behind the radio? Anyone have any pics or diagrams for this?
