ScAndal Posted May 3, 2007 Report Share Posted May 3, 2007 I hooked up power, ground and 12v constant and it doesn't power up. Does the unit not power on if there are no speakers attached? ScAndal Quote Link to post Share on other sites
cntrylvr79 Posted May 3, 2007 Report Share Posted May 3, 2007 so you've got red and yellow to +12volts and black to ground? If the unit doesn't power up check the fuses on the harness. Any avic will power up without speakers hooked up to it. mine does every day and I have exactly 0 speakers hooked up to it. Quote Link to post Share on other sites
