so im trying to figure out which way to plug these RCA jacks together. i know which pair goes with which, but i have no idea what colors to match up....can anyone help? also when using the RCA jacks, does that mean i dont have to do anything with the grey/purple/green/white speaker wires coming out of the one f90bt harness?

 

noone?

thanks, but the back of the metra package says that. i just dont know which color to plug into which color. like which colors(red and white) are positive and negative on the f90bt haress? im going to assume red is positive and white is negative, but i just want to make sure.

 

I think the positive and negative speaker wires are connected through the harness. For the RCA cables, just make sure they match.

White - Left front
Grey - Right front
Green - Left rear
Violet - Right rear

 

did you even look at the picture i posted?

the violet and green RCA's need to plug into red and white RCA's....how do i know which color plugs into which color? the f90bt manual doesnt specify which color(red and white) is pos and neg

same thing with the white and grey RCA's...they need to plug into red and white RCA's....what color matches up with what color?

 

The positive and neg. wiring is connected at the harness and has nothing to do with the RCA cables.

 

sorry i meant left and right....i dont know why i said pos and neg

is red left and white right? is red right and white left? i dont know...the manual doesnt say

 

Let me check.

 

stock bose system...hence the need for me to use the 7551 vs. the 7550 metra harness

 

Red = Right
White = Left

 

thanks!!

and you got this info from where?

 

Its the standard for RCA cabling. Its the same for everything. I have books on car audio.

 

duh!!! wow....i dont know why i thought car audio RCA's were any different than any other RCA's....wow....now im embarassed.

why would metra not just make their plugs red and white, since RCA plugs are standard red/white everywhere else?

 

Are you doing the hardware bypass on your F90bt?
