alright, one more thing. if you could just help me out with my specific equipment. you can see what i've got in my sig... now, i would run one of my three preouts from the HU to the line driver as close to the HU as possible, then from the line driver to the amp. so, does that mean i would need a seperate line driver for every amp i'm running? in my case, two? one for the front components, and one for my sub? next question... what would that do for my gain settings on my particular amp... it's lowest setting is 4 volts... so, where do i set it with a line driver? also, what kind of current draw is a line driver going to take? is it enough to ammount to problems if i'm almost pushing my altenator as it is? last question... would i get much benefit from a line driver without anything else? what i mean by that is, would i notice a difference with just a line driver and no other goodies from audiocontrol like an equilizer, x-over, etc... sorry about all the questions, but thanks for the help!
