@289vert it's all good! I still like my USA-66. It has an AUX input so I can plug up my phone etc, or I could put a BT receiver on that and go wireless, and I could add more speakers with or without wires. I just don't prefer the look of kick panel speakers, don't wanna cut my solid doors for door speakers, and I plan to cover my rear package tray with a cloth with a pattern and color close to the original to hide the triaxial Pioneer 6x9s in the back. I LOVE the original look with that "Where did THAT come from!?" sound quality. I am all about hidden mods...
