Just for you:
Tweets = tweeters
Mids = Mid range speakers
SQ = Sound quality
SP = Sound pressure ( the more bass,the better )
Active cross over = Cross over that needs power to split the signal into high,mid range and low frequencies
Passive cross over = Same as Active,but doesn't use a power sourc
Staging = When you go to a concert the music comes from the stage.The same can be achieved by placing the tweeters and midrange in the right position in a car.Bass is non directional and can be placed anywhere in a car.
Kicks = kick panels
Head unit = Radio
Hope that helps.
