I have a 2007 scion tc i have brough it to the service shop numerous times. My stereo cuts in and out like there is a loose connection somewhere. They installed a new receiver but the waranty didn’t cover rewiring. Power can be off in the stereo and i can still hear cracking in the speakers does anyone have any input on what could be wrong?
I have a 2007 Scion that I have put in a newer model stereo with a Stock sub-woofer (2008 or 09 Stereo). I can not find the wiring for the sub-woofer. When I hooked up the stereo with the orginal wires, there was 1 connector that was taped to the wiring harness that hooked right in to the stereo. The problem is that there is another outlet in the back of the stereo that doesn’t have a connector. Is this for the sub? If so where can I purchase this extra wiring harness? The serial # on the stereo is GDPG010885UC if this helps. Thank you
