Hello Fellas, Recently I installed a JVC KW XR610 which puts out 22 RMS as I understand and really like the unit but the oem speakers sound like crap. I want to upgrade the speakers. I DON'T want to add a amp I just want a decent sound with just the HU. I researched some speakers and the POLK db 651 and the Alpine SPS 600 are at the top of my list. I wanted to know what you guys thought. Let me know what has worked for you without using an amp. Thanks fellas, :hi:
