I have a BNIB Coustic XM6. Was going to use it to go active with some SPX-177R's, but I never installed it and have since got rid of the car. For that matter, I have the SPX ready to go, as well. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
$55 shipped USPS Priority to the 48CS for the XM6 if it's something you can use. It's got a limitation... the band pass only goes as high as 3K. Here's the manual in PDF is if you want to check out the specs. I can get pics posted this evening if you need them.
