This is amusing.

A while ago, I posted a situation where I could hear a low grumble from my sub. I thought it was feedback from a power short or maybe a RCA issue, but it turns out that what I am hearing is EVERY STINKING BUMP OR ROUGH PATCH OF ROAD I DRIVE OVER!!!! I get a grumble when I hit anything not smooth on the road. Now that I have discovered this, can anyone help me rectify it?

Just to recap, it's an infinity 10" ported, powered from a RF T400-2 bridged pushing 512 watts. RCA's are Knu Klear. Deck is a Pioneer DEH P7800 MP

I checked and double checked the grounds. I'm gonna check the RCA's in the morning, though. Didn't go behind the dash because that takes about 30-45 minutes.
