Creaver 55 Report post Posted July 1, 2009 Hey guys, I've wired my headunit up, it turns on etc, but no sound comes out. I suspect the factory amp has something to do with this? I've read on the net if I bypass this completely, I will lose the use of the cross-over and only be able to support 4 speakers, instead of the 10 I currently have. Please let me know your thoughts and some ways of getting around this. Cheers, Ian. Quote Share this post Link to post Share on other sites

Creaver 55 Report post Posted July 1, 2009 Hey Brent, i've just had a look and no, there is nothing connected to the white wire. I don't think there ever was? I will splice it into my switched power and give it a go, if still no luck ill give you a call, thanks. Quote Share this post Link to post Share on other sites

Greg111 13 Report post Posted July 2, 2009 Ian, i had the same prob with mine when putting in the aftermearket stereo then realised it had the factory amp which i had to power up, the blue wire on the head unit is the remote amp turn on wire, just used that one.

pureboiracer 0 Report post Posted July 3, 2009 sometimes the blue wire or the amp power craps out in the head unit. in which case just power the amp off a accessory wire. ie cig lighter. Quote Share this post Link to post Share on other sites
soarer260@hotmail.com 0 Report post Posted July 3, 2009 Hahaha I did the exact same thing too when I put my HD in the 540i a few months ago. Worked out what I had done wrong after a a period of cursing. Quote Share this post Link to post Share on other sites
