[QUOTE="sam_b03, post: 8098860, member: 607518"] Google "setting gain with ddm" Ohms are the unit of measure for electrical resistance. The ddm sends a specific voltage with a specific amperage known to the meter. Using ohm's law that states it take 1 volt with 1 amp to cross 1 ohm of resistance. If the meter reads 0 or close to it you have a short. If it reads I or infinity then you have an open circuit(blown). The reason for 3/4 HU volume the signal can become "dirty" above this. By doing this it you never want to turn your volume above this level because your amp is sendong out most signal while still safe for your speaker. Once it is done. If You want to, use the HU settings to up the sub level at normal listening levels. Remember to turn it back dow. If you are showing off or cranking it. [/QUOTE]
