Hello All, I just bought a 2008 Commander and am still learning my way around it. Didn't realize until after i bought it that the passenger floor was soaking wet. Reading up on it now i see that that's a common problem. I'm hoping it turns out to be simply clogged sunroof drains so fingers crossed. But also none of the speakers are working on the right side. All left side speakers work fine. If it was just one i would guess blown speaker but all three I'm thinking is a wiring issue. What's the easiest way to test to see if it's the wiring or the amp or the head unit? I have a multimeter, just not sure where to start.
