Drivers side b-pillar Line output converter?

[Goinovr]

I ended up running all my wire for my sub down the drivers side and was going to tap into the speaker wires for the rear at the B-pillar. Trouble is the only colors that seem to match the diagrams I've found are only for the drivers-rear. I was wondering if anyone had tapped into the system in the same area or if I should just tap in somewhere else or if I just need to look further up the harness for the wires.

Speaker wire colors for non-Bose:

 

Left Front Speaker (+/-) // blue - brown/blue // radio, green 16 pin plug, pins 1 - 9

Right Front Speaker (+/-) // yellow - yellow/black // radio, green 16 pin plug, pins 2 - 10

Left Rear Speaker (+/-) // green - green/black // radio, green 16 pin plug, pins 3 - 11

Right Rear Speaker (+/-) // white - blue/black // radio, green 16 pin plug, pins 4 - 12

 

I tapped into the rear door speaker wires where they meet the rear door jam in the b-pillars. Green and Green/Black on left rear, White and Blue/Black on right rear.

Thanks. this is exactly where I ran my rca's for my LOC. I was looking for a white/blue and a blue/black. Didn't want to tap into wires and have my window no longer roll up or down. haha.

Lack of sleep but it finally dawned on me that you're saying the left and right are on either side of the truck and not together on the driver side b pillar. Hmm. May have to get creative for the other channel.

 

I was going to run my amp bridged into my sub.

[Fasthotrod]

Correct. One pair on each side. You could run each pair from each pillar to the amp, but if your plan is to bridge the amp then a single input should suffice. Typically most sub-bass frequency content is mono anyway, so I doubt that you would notice a difference by using just a left or right signal.

FYI, be careful where you grab the signal from. The truck has crossovers split throughout the cab. You have 4 signals leaving the headunit. The mids have a crossover at some point throughout the dash so you would not want to use the signal at the dash speakers. Not sure about the rear doors but I would tap behind the headunit for a solid full signal. Ideally, you would want a full front and full rear signal and then sum that up as 50% full front signal and 50% full rear signal to get as much information from the system as possible but if your LOC does not have summing, then tapping the rear signal wires would be fine.

I'm still confused. I have 2016 Silverado lt. I have the 16 pin connector but I see no white cable. I'm just wanting to run 1 amp for bass. I want to connect from the dash board please give me easy instructions
