Hey bud.
Do you have 6x9's in the parcel tray installed? If so, you attach the Line Level Conveter to each speaker. (So it gets the Right/Left Audio Signals).
Then from the converter, you attach RCA cable which goes to the amp.
Power cable and Rem wire: Both down drivers side, I made a hole in the main loom grommet on this side and fed it down. Under kick pannels etc.
Rem Wire, i installed a switch which on one side, i went to the amp, other to the ACC wire in the head unit(i used actually off the mobile phone plug)
Where about You located?
