It shouldn't be too hard to set by ear...just get a couple of extra 12 ft RCA's and some RCA barrell adapters and lengthen the power wires so yu can adjust it from the drivers seat...then demo all sorts of music through it...after you set it...That's it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif you can re mount it back in the trunk and you are good to go...make sure your radio tone controls and loudness are set flat while adjusting so it gives you a little play afterwards...//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
