They sound really good, a little uneven with the stock front speakers but it's nice to have music on the highway.
There is a bit of a whine coming out of them, it seems to be dependent on HVAC and RPM. Max HVAC fan and low RPM on the trail, no whine. High RPM on the highway, and it goes up/down with the HVAC fan. Doesn't go away completely with the HVAC off. I'm thinking it might be the ground?
I'd ask some of the more knowledgeable stereo folks.
