I installed a LUX Amp and TNR in my 07 Lt and the Left speakers don't work. The Right frt and rear work good. Any Idea what my be wrong. All the wires were checked and they are in the proper location.

Was the amp new or used? Sounds like the amp needs to be calibrated/programmed. What's the part # on the amp?

The amp was used. I will have to get the part # in the AM.

Triple check your wiring. Just because you have the pins in the right spots doesn't mean you have good connection. Also check the drain wire...thats one that gets missed.

Yes, my left rear wasnt working and all I had to do was remove the wires for that speaker from the plug, and pinch the part that receives the pin. It wasnt making contact when plugged in.

What does the drain wire do?

What does the drain wire do?

Ground wire. You'd be surprised the number of people that forgot to move that wire over to the other connector.

Thanks for the help. It was the conectors. I got it to work last night. It sounds much better. I am glad I did it.
