Depending on your amplifier, it could allow you to output low/hi sound levels to another amp.

If it's from your head unit, and you have more than 2 pre outs, then definitely yes.

I'm guessing it's the preout from the amp, which I would need more info to give you a better answer.

E.g.
Which preouts from your headunit did you connect to your installed amp?
Does the preout on your installed amp have a HI/LO pass filter?

I'm using the stock hu. so the amp does take hi/lo - its a pioneer gm-6200f (http://www.pioneerelectronics.com/pn...568903,00.html)
