I recently bought my 2010 Volvo XC90 and am wondering if it's possible to easily connect an amp and sub that I have lying around from a previous vehicle. Searching through many of the threads here I haven't found a straightforward explanation yet. is it possible to use the factory head unit? Is there a step-by-step anywhere of someone else's similar install?
The amplifier is a Rockford Fosgate Prime R500-1 and subwoofer is a Rockford Fosgate 12" P3. Thank you.
