I just picked up a Silverado 1500 LT with a Crew Cab and decided to add some base to the factory stereo. Initially i was going to post this here to tell you how to get the speaker signal from the back door wiring harness but since i am already here i figured ill post some images as well.

Get your tools and materials together

 

[diazwhiskey2]

2-RUN POWER AND REMOTE CABLES. MAKE SURE TO STAY AWAY FROM ANYTHING THAT GETS HOT OR MOVES.

 

[diazwhiskey2]

I CHOSE TO RUN MY REMOTE WIRE STRAIGHT FROM THE FUSE BOX. OUT OF THE FUSE BOX AND ACROSS TO BE RUNNED ALONG WITH THE MAIN POWER CABLE.

 

[diazwhiskey2]

THE FUSE NUMBER IN MY TRUCK WAS #39. IN MY TRUCK THEY USED MICRO FUSES INSTEAD OF MINI. I COULD NOT FIND A MICRO (ATR) FUSE TAP TO ADD A CIRCUIT SO I SOLDERED THE REMOTE TO THE BACK OF THE FUSE ONLY UNTIL I CAN FIND A TAP SOMEWHERE TO DO IT RIGHT. THE SMALLEST TAP AT THE LOCAL AUTO-ZONE WAS THE MINI AND THAT ONE IS TOO BIG.

 

[diazwhiskey2]

(ATR Fuse Circuit Tap KiT) IS WHAT YOU WANT TO USE SO YOURS DON'T LOOK LIKE MINE LOL

 

[diazwhiskey2]

AFTER YOU RUN THE MAIN POWER AND REMOTE CABLES OUT OF THE ENGINE BAY REMOVE THE DOOR JAMS.

**MAKE SURE AFTER YOU FIGURE OUT HOW YOU WANT TO RUN YOUR CABLES OUT OF YOUR ENGINE BAY YOU REMOVE DISCONNECT THEM. YOU DONT WANT THEM GROUNDING OUT ALL OVER YOUR CAR AND DAMAGING SOMETHING ELSE.

 

[diazwhiskey2]

REMOVE THE WEATHER STRIP BUT ONLY TO ABOUT THE HEIGHT OF THE FRONT SEAT. YOU NEED THAT OFF BEFORE REMOVING THE CENTER POST COVER.

 

[diazwhiskey2]

REMOVE CENTER POST COVER. YOU NEED THAT COMPLETELY OFF SO YOU CAN GET TO THE PLUG THAT FEEDS SIGNAL TO THE REAR DOOR SPEAKERS.

 

[diazwhiskey2]

PULL IT STRAIGHT OUT SO YOU DONT BREAK THE FASTNERS

 

[diazwhiskey2]

RUN THE POWER AND REMOTE WIRES INSIDE THE WIRE RAIL UNDER THE DOOR JAMS ALL THE WAY TO UNDER THE REAR SEAT

 

[diazwhiskey2]

HOOKUP YOUR GROUND CABLE TO THE BOLTS THAT HOLD THE REAR SEATS TO THE CABIN.

 

[diazwhiskey2]

REMOVE PLUGS FROM INSIDE CENTER POSTS.

 

[diazwhiskey2]

TOUCHING THE TERMINALS ON THE PLUG ON THE DOOR SIDE WITH A COUPLE OF WIRES POWERED BY A BATTERY IDENTIFY YOUR SPEAKER WIRES. WHEN YOU APPLY A SMALL AMOUNT OF POWER TO THE SPEAKER YOU WILL HEAR NOISE COME OUT OF THE SPEAKERS.

***MAKE SURE YOU ARE APPLYING POWER TO THE DOOR SIDE AND NOT THE CAR SIDE SENDING POWER BACK TO WHO KNOWS WHERE ON YOUR CAR. YOU WOULDN'T WANT TO DAMAGE YOUR BRAND NEW TRUCKS ECU.

 

[diazwhiskey2]

IN MY TRUCK (2014 SILVERADO 1500 LT CREW CAB) THE WIRE CONFIGURATION IS AS FOLLOWS:

RIGHT/REAR: PIN 14-BLUE/BLACK
PIN 7-WHITE

LEFT/REAR: PIN 7-GREEN
PIN 16-GREEN/BLACK

 

[diazwhiskey2]

I DONT KNOW ABOUT YOU GUYS BUT I NEVER WANT TO TAKE THIS APART AGAIN TO HAVE TO FIX IT SO WITHOUT CUTTING ANYTHING I SOLDERED A PAIR OF WIRES TO EACH SIDE AND RAN THOSE WIRES TO UNDER THE BACK SEAT.

 

[diazwhiskey2]

ONCE I RAN MY SPEAKER SIGNAL WIRES TO THE BACK SEAT I WAS READY TO INSTALL MY HI LOW SPEAKER LINE LEVEL CONVERTER. THIS CONVERTER TAKES THE SIGNAL FROM THE SPEAKERS AND CONVERTS IT TO RCA TO FEED THE AMPLIFIER SIGNAL.

 

[diazwhiskey2]

IF YOU ARE FOLLOWING THE STEPS THE SAME AS ME YOU SHOULD NOW HAVE EVERYTHING YOU NEED UNDER THE BACK SEAT TO MAKE YOUR AMP WORK.
1-MAIN POWER
2-GROUND
3-REMOTE POWER WIRE
4-RCA SOUND SIGNAL

THE ADDITIONAL BROWN CABLE YOU SEE HERE COMING OUT OF MY HI LOW SPEAKER LINE LEVEL CONVERTER IS THERE IN CASE YOU GET ENGINE NOISES. IF YOU DO THEN HOOK IT UP TO GROUND. IF NOT BE HAPPY.

 

[diazwhiskey2]

NEXT STEP IS TO INSTALL YOUR AMP AT YOUR DESIRED LOCATION. MOST PEOPLE INSTALL THEM BEHIND THE BACK SEAT TO HAVE MORE ROOM FOR MORE THAN ONE SUB. I AM ONLY DOING ONE SUB SO MINE IS STAYING UNDER THE BACK SEAT.

BEFORE YOU PLUG YOUR AMP IN MAKE SURE TO REMOVE THE FUSES

 

[diazwhiskey2]

NOT A BAD IDEA TO TAPE YOUR RCA CONNECTIONS TO PREVENT THEM FROM COMING LOOSE AND GETTING NOISES
