runnin dual batts?
I haven't been under the HHR yet, so I don't know. Couldn't someone make a tray for an extra battery and mount it under the car? Maybe there isn't room, but coming from a custom truck background they are always building little compartments to hold batteries, air compressors, and gas tanks just to keep them out of the way. Just an idea, so you don't have to cut up the rear tray.
i did steal e0nami's (sp?) idea and change all my inside lights to blue so my cluster is blue with red needles at night, b4 its ove though ill end up with those gauges...
