im currently driving a 2013 evo x gsr. it came with no sub or amp. i recently bought the oem amp and sub from a gentlemen parting out a 2009 lancer se. i figured mitsubishi wouldn't be stupid and have a different harness for a car with or without a sub or amp. i also figured they would use the sub and amp across all the trims. i have located the sub wiring in the trunk and i connected everything bolted it in. now im looking for the location of the amp and the wiring harness but i cant locate it. has anyone done this before? can anyone help me?
