The only thing I can tell you, is that if you want these speakers for bass, that's a no-go. These speakers do not put out ANY kind of low-end bass at all. The only type of bass they are capable of, are tight, punchy bass, but that is about it. also, these speakers sound best in an infinate baffle type enclosure (just in your door, not in any kind of enclosure) they are actually made NOT to go into an enclosure, so they sound even worse in an enclosure, than not in one.

Due to the angle of the car it is nigh on impossible to judge where the back end is when you are reversing due to the angle of tilt. Fine, I could retrofit a reversing sensor device and that would solve the problem. But it does not address the original problem of the design. 2. trailer repair
