I have a 2009 JKUR and have a few stereo questions.
1) I have the dash tweeters and sub in the back. How do I verify if its the alpine or infinity system?
2) Are the lines running to the dash tweeters and speakers full range?
3) Does the sub run off a separate amp? If so has anyone rewired the sub to connect to the sub output of an aftermarket stereo? I would like to control the frequency and level at the head unit.
