Hello guys, I need help with a setup that I'm trying to install for my dad. He has a Pioneer DEH-15UB and a Kenwood KAC5204. I know enough about wiring but a bit confused with the setup im trying to obtain. He's not looking for bass, just nice crisp clean music. For speakers, he has in the rear, Sony Xplod XS-R6944 6" x 9" 4-Way Speakers and in front which we have relocated to the doors, he has Scosche HD4603 - 4" x 6" 3-Way which sound surprising great. He wants to connect all 4 speakers to amp which is no problem but I'm lost how to wire the radio. Do I still wire the front speakers accordingly and do I use the speaker level input on amp. All speakers run at 4 ohms......Thanks to those who reply!!
