No I dont hang around many sales people. Actually I bought my kit from a local car stereo store for about 40 bucks and did the install myself. And I guess you dont see the high heat in the engine bay as an "element" I guess your engine is sealed up completely from all elements. You must like keeping your engine nice and warm sealed up good to keep out any humidity or moisture from the road out of the engine bay. Seran wrap your entire engine bay? The best way to avoid elements would be to keep the battery in the backseat, and have the entire inside completly sealed up, never open a door or window and always have the A/C on.
