    preamp voltage

    The higher the preamp voltage in the Head Unit the higher your able to crank your gains, therefore your subs will then hit harder, am I correct?

    No. Preout voltage has no influence on how hard your subs hit.

    Isnt it that the higher the preouts the lower you have to turn your stuff up meaning less distortion? That's how I always thought about it.

    Higher signal-to-noise is good or bad? Lower gains are always nice

    but, if you have a 4volt preout, then you don't want your amp gain set at 4 volts because you want to hit max power at about 2/3 of your max reciever volume, correct?

    well, i'm not interested in getting more power... i was just told that your head unit sends out a distorted signal at its highest volume settings. which, i'm still not really clear on... what i want is the best possible settings to give me the least distortion and best sq. can you help me out jmac?

    well, i've got the alpine 7998... with the gain set at 4 volts, it doesn't seem to sound distorted to me even at volume 33 or 34 out of 35... but, they say distortion can be hard to hear, and i wonder if maybe i just don't have an ear for it. let me know what you think, and thanks for the help so far.

    well, that takes me back to the original question though... i guess what i really want to know is what are the benefits of a higher voltage signal, and where do i want my max power to hit in relation to my HU's volume control. sorry for asking so many questions... i just feel like i'm having a hard time grasping the facts in this one.

    well, yeah that helped... i don't know if you realize this or not, but i'm not talking about a sub amp, but i'm refering to my component amp. does that make any difference? my HU doesn't have an internal amplifier so its not powering anything.
