^^that's my setup in my car with the exception of the wiring kit. How can I tell what level to set my amp at? there wasn't mention of it in the installation kit

Answer 1

When you say set the voltage or set the level, I assume you're taking about the gain.  The gain is set based on the output voltage of the head unit.  Try this, http://www.installer.com/tech/gains.html  or Google setting gains and pick any number of sites that explain various versions of gain setting.
