Hi, I'm looking for the wiring diagram or color codes for the left and right rear speaker wires that run in the pillars just next to the seats where the seat belts are for my 2008 Dodge Ram Quad Cab. I'm trying to tap into them for my MTX Thunderform. Also the speaker wires in all four doors. I checked the 2006 and 2007 postings, and the door speaker wires are almost identical, but the rear colors are slightly off. I just want to be sure, and it would help others if they have any doubt. Thanks in advance.

Thanks,

It is a 1500.

The colors you listed for the rear speakers are not in the bunch of wires inside the pillars where the seat belts are, or inside the door itself. The spot I asking about is where the harness comes from the rear door and goes into the pillar/post.

Also, if it helps, it's only a standard 4 speaker system.

Well, I'm going to try a couple wires today, the truck is already semi-torn apart and I need it back together later today. I guess it's trial and error time.

Well, looks like the wiring in those post/pillars is the same as the 07 Ram. There were 3 other pairs of wires in each side, so I was a bit concerned and wanted to be sure. I double checked the 2007 Ram wiring and decided to try those out first. I still have to check the door speakers and see what colors they used in the doors. But for now I have the MTX Thunderform hooked up to a MTX 6500D Class D mono amp via the speaker level inputs. They sound decent for what they are, but I'm used to a higher quality sub. I'm not saying MTX isn't quality, just they put the bottom of the barrel sub they make in this box. I'll have to look into a better series they make.

For those interested:
