Is A Line Driver Needed?

I was talking with a guy at Phoenix Gold this afternoon, originally to discuss a question I had about their amp (see my posts on this thread), when we started to discuss various other options, including the Phoenix Gold Line Driver (TLD22).
I am very skeptical that this would really add anything to what I think will be a good setup (Alpine CDA-9813 HU, Phoenix Gold Tantrum 600.4 amp, MB Quart RCE-216 Reference Component Speakers, and eD e8A.44 Subwoofer in HLAURANT enclosure).
I understand the concept of what a line driver does, but with good patch cables between the HU and amp, wouldn't the 4 volts output of the HU be sufficient? Would doubling the output to 8 volts really be that advantageous? I would definitely say yes if the HU output was only 2 or less volts.
At this point in time, I'm leaning against adding this unit. However, I would like to hear some of your thoughts on this matter. Is anyone using a line driver, in their setup? Please no
. Thanks!

Mike,
there's been debate on the boards that the sub-woofer output on the new Alpine head-units are weak (i.e. not 4 volt) i haven't been following it too closely but there's enough evidence to make me wonder. my suggestion would be to go without one and add it later if the subwoofer sounds weak. i really don't think you'll have that problem...

4 volts should be more than adequate for your needs... 8 volts seems a bit much to me... i doubt the noise rejection will be necessary and your amp will produce full output even if you use a 4 volt preamp signal.

actually -- the whole alpine -15 db vs +15 setting is sort of an inside joke for us...
thread on related issue... needless to say, it's a rather boring and tedious read w/ lots of me being pissy cause i was tired...
. since that thread, i've spoken w/ some tech heads, and i was instructed that at +15 (0db reduction) the pre amp outs produces a 4v signal and that as you dial down closer to +0 (-15 db reduction) the pre-amp signal drops off dramatically (even to the point where the input gains of some amps cannot properly compensate).
