[QUOTE="keep_hope_alive, post: 8317174, member: 576029"] correct. you prefer to have more power than you need so the amp gains are left low and you have dynamic range. where you place the sub in a vehicle is vital. we hear sound directly from the sub and then all of the reflections off the walls/floor/ceiling/rear/etc. bass frequencies have wavelengths measured in feet (100Hz is about 10' long). when you have a reflection that is about 1/4 wavelength away (or 2.5ft at 100Hz) then the result is a cancellation (wave travels 2.5 feet to the surface than 2.5 feet back to the box - a total of 5 feet or half 10 feet). so that reflection perfectly cancels at 100Hz. this problem occurs several times in the trunk/rear of a vehicle. by placing the sub in the corner you eliminate two of those cancellations. you still get a reflection off both side and rear but they are so close it is as if you have two more sources. it's easy to test for yourself. get some sine sweeps (20-200Hz) and play them with various sub positions. the corner will appear to be the same volume throughout the sweep while other locations will get louder and quieter in certain spots.
