Also, just for clarity, voltage is dropping at higher notes, not lower notes, voltage doesn't go below 14 at anything 45hz and below
Ahhhhhhhh that makes more sense. Car has a factory sub, bet the loc is tapped into the rear speakers like was said. Most "premium systems" have hp filters for the front and rear speakers. Hence the reason if the loc is tapped into the rear speaker leads there is little to no sub bass. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
