Hey, I just installed a pre-amplified sub to the OEM sound system. The huge problem is that I can't find a good source for my remote wire. I tried taping into the rear speaker wire (this has worked on my 09 Yaris and 08 CSX-S) but it doesn't seem to work here. I then ran the remote cable to the fuse box. Here I used an ''add a circuit'' and tried multiple fuses but when I turn the car off, the amp still stays powered (even if I close the doors and lock them). I know that some fuses stay active up to like 15 minutes after the car is off so I decided to have dinner and go check after and it was still on... This car does have keyless entry, could it be that it's powering on as soon as I approach the vehicle? P.s. I even tried the radio fuse and it still stayed on.
