Yesterday, a buddy of mine (edeekeos on the forums) were swappin' out trunk setups..
On his way there, he was listening to his system, no problem at all, headunit worked 100%..
After installing my Kicker 1k & M3's into his ride, we turned his ride on.. & boom, NO power to the headunit..
We checked all his fuses, nothing blown, replaced them just in case. Still nothing.
We janked my 7800 outa my car, put his in, NOTHING.
Put my 7800 in HIS car, turned right on.. no issue whatsoever..
WTF is the issue..
