No, I don't have an amp in yet but plan to install one. I'll attach it to the panel outside the car then put the panel back. I did have a chance to pull out the carpet and back panel and didn't see anything obvious. The sunken well on the passenger's side smelled of diesel but I didn't see any drips or obvious leaks. The car hasn't leaked in a while. I suspect that it may be the gasket where the cap fits. The car stopped leakin fuel when I got to 1/2 a tank.
