    I have the perfect gf radio for you: Used Alpine CDE 7821 with front and rear RCA's (the rear can be made to not fade for use with a subwoofer). It even has a 1-bit DAC. It was used for 4 years in a company car and has been in storage for a couple of years. It is in EXCELLENT condition.

    I am new here, but have 100% feedback on Ebay, soundillusions.net, tundrasolutions.com (where I am the A/V moderator), and a few deals on elitecaraudio.com

    Click on the "Tech Center" button under the Alpine banner and then search for your head unit.

    It'll give you a link to the .pdf file for your owner's manual.

    Gotta have Adobe Acrobat Reader to open the file
