wire color behind stock radio, installing Options

[Cormudgen]

hello,

i'm looking to find out if anyone knows what color the wires are in a stock harness for a rear speaker. i'm putting in a line level converter right behind the radio b/c i already have rca's run from there and need to keep them there for when i put in anohter aftermarket deck. from lookin at where an aftermarket harness plugs into the toyota one, the right rear ones seem to be a red and white wire but that just doesnt make to much sense to me and i want to verify before i start splicing into stuff.

thanks

Ok, i rechecked ALL the connections and made sure they were tapped into the right wires. Everythiging is ok. I also checked for an adjustment knob or off/on switch on the line level converter. There is no such thing. I am completley puzzled. For ****s and giggles I'm going to pull my sub out of my box and make sure the interior connections didnt come loose but that seems highly unlikely. I swear i'm just about to go buy another aftermarket head unit. Seems so much easier.

Lastly, on my line level convereter-I pulled it from my friends M3 that he had a profesional shop install it on. They had put caps on the wires that let you snap it in and out. I bought the female counterparts of those and that is what I spliced into the red/white faccotry wires behind my head unit. This line level converter also has 2 brown wires coming out of it that they had completly capped off and were not being used. I have heard those are only to be used if you are gettin line noise. What can you guys tell me about those?
