I have an Alpine 9805 which has a 4 volt output voltage. The front and rear outputs go to a 4 channel Kicker 600.4 and the sub output to a Clarion 1000DPX. Would I get clearer and cleaner sound if I installed a higher voltage line driver or would it just be a waste of money?

Actually a 4 volt output is good. What I usually do when connecting more that one amp is run a relay from the remote turn-on. This will elliminate the delays.

Do it right the first time
If you have your gains cranked on your amps right now you probobly should consider a line driver (which would improve your signal to noise ratio, reducing backround hiss if there is any). That Alpine deck will probobly only produce 4 volts out of its preamp output when its clipping. Audio Control makes good line drivers.
^ good advice that money cannot buy. The Alpine 4 volt preout is usually measured at 1000hz, anyone can make power at 1000hz. My bet is that your sub level preout is probably closer to 1.5 - 2 volts before it clips when used with the appropriate test frequency (meaning 100hz or less). Thus a Audio Control line driver would be a good choice. The EQS would be a devastating eq / line driver to add to your system.
The other option (waits for some to say I told you he'd say it) is to upgrade the cd player to a nice fine Eclipse CD5444or and not have to worry about an outboard eq / line driver etc. The more streamlined you can make your system the better ir will perform. There are very few cd players that I will group in with Eclipse, sadly Alpine is not one of them but they used to be a looooong time ago.

Top Secret, I can tell you but then my wife will kill me.
I love the quick plugs for the eclipse in your posts. Anyways, the phoenix gold line driver is nice as well.
