Do a search for "setting amp gains". it will walk you through how to properly setup the gains on the amps, where to put the volume on your headunit, all that good stuff. The settings will be different for every system, just read and have fun tuning...

Here's a start, I just pulled tyis off the list of hundreds of results in a search: Setting gains

Post back when you've read enough to understand the process of setting amp gain to match headunit output, if you have something to ask about it. As for the sub amplifier, set lowpass to the range of 80 to 100 Hz (experimental), and set subsonic filter to the tuning freq of the box.

search for how to set gains

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
