Im just wondering, what exactly do line drivers do? will i notice much of a difference if there going to an amp powering a sub, or are they mainly for amps powering speakers? i dont know much about them at all and a friend recommended them to me.
They are a way to increase the RCA RMS power(this will allow you to use lower amp level settings which will decrease noise). They will accomplish this for any amplifier whether it is hooked to subs or satts.
