So the Jensen SUB-1RR came today. It's much heavier than I thought it would be. I hooked it up and no more hum when I touch the sub cable to metal!
That's the good news. The bad news is the noise I'm hearing is still present from the sub.



So, I decided to call Hsu about it. I called there customer service and the woman took my info and said someone would call me back. Sure enough about 10 minutes later a guy called from tech support. Very knowledgable and very helpful.
I went over what's happening and he right away ruled out the ground loop. I let him hear the noise over the phone (surpised the worked). He thinks it's either the amp or the driver (what else is there?
).Anyway, he gave me some homework to verify whether it's the amp or the driver. Hopefully I can get to it this weekend.
Not sure if I'm keeping the Jensen, we'll see about that. Not that I think the Jensen wasn't working, it just didn't fix this problem.
