Default 1999 LS 400 Pioneer Amplifier

I have a rear left speaker that is out and was told by a tech that it's most likely the amp that is bad, not the speaker. Before i go out a pay a fortune for an amp i'd like to know if anyone knows where i can get a wiring diagram for the pioneer amp, so i can try to bypass the amp to narrow it down to the head unit or amp.
