Thinking about getting this to boost my preout voltage (2volts). What do you guys think? Will I suffer any quality loss or gain? I know this will clean my signal up right?

all the specs seem right, but i have never been a fan of line drives what is the problem you are trying to solve with this?

I used to use a Pheniox gold PLD1 and loved the thing, I only got rid of it because I use a 3.1 in dash preamp now. Its in my freinds car now. I have never had a problem using line drivers as long as you know what your amps limitations are as far as input voltage goes. Inputs are very easy to blow with too much voltage.

I'd look at the Audio Control Overdrive line driver if I were you.  In fact...look at what I found here https://cgi.ebay.com/dll?ViewItem&category=79842&item=5723166912&rd=1

Here is the manual.

From what I understand if my amp is putting out full power I don't need it?  My sub amp is puttng out 37volts and the four channel amp is putting out 18volts so I should be good to go?

Output voltage on the amp is adjusted by the gain, so with as little as half a volt of input you can get the output voltage to those numbers.  But, when the amp is getting a signal of half a volt, or one or two volts...it has to amplify that signal to reach the desired output (by increasing the gain).  When the source signal is faint, the amplifier is increasing the signal-to-noise ratio when you adjust the gain to get that output.

Now, the idea of using a line driver to increase the source signal has to do with getting a better signal-to-noise ratio from the amp.  If it is getting a 6 volt signal (and the amp is spec'd to be able to use 6 volts input), then it has to do less amplification of that signal to get to the final result.  You should always try to feed an amp the strongest input that you can, for this reason.

It was asked earlier what problem you are trying to correct by looking at using a line driver.  Do you have the system up and running now, and is the sound unsatisfactory?  Do you need a cleaner signal?  If so, use the line driver and position it close to the head unit.  If there isn't any problems, and you are happy with the sound...leave it out of the equation.

It sounds good! I just wonder what I else I can do to get the most out of my system..I like to tinker!  LOL
