Powered subwoofer install into a 2017 Silverado DC

[Steven Muraoka]

I am looking to install a 10" Rockford Fosgate powered subwooferm (P-300) into my 2017 Double cab.

I do not have the Bose system or Navigation. Audio-wise, everything is stock.

I understand how to run the power and ground wires for the sub. What I have questions on is how to obtain a turn-on signal for the amp, and how to locate/tap into a non-RCA source.

I have read that you can use the rear speaker wires as a source. True?

I'm curious to see how this is done, as I have the Rockford sub from another truck, and would like to use it in the Silverado.

Thanks for any help or advice!

You need a line level converter. If your running rca to the amp if amp have a hi level input then you dont. Some converters have a signal sensor and will give you a output. Or rap wire in fuse box and FUSE it. Speaker wire can be tapped into in sil panels.

The P-300 has speaker level input so adding a line converter isn't necessary.  You can tap into the rear speaker levels on the none Bose system in the B-Pillars.

 

ITEM WIRE COLOR LOCATION

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
 

The P-300 also has "Intelligent auto turn on/off function" using audio sensing, meaning as soon as the internal amp senses power on the speaker inputs it's turns on so no need to run remote turn on lead

 

Let me know if you get stuck, I just added a Sub and AMP last week, none bose using above wires and it pounds.

Thanks so much for the info! I may try hooking the sub up over my winter break.

Styles,

 

Just out of curiosity, where is the best place to access these wires if I run the sub under the rear seats? I know the obvious answer would be through the door panels, but are there "easier" areas to access the wires?

Thanks!

Sill panels is best. And if I remembered right you need front speakers not rear. Rear is a mid bass fill signal but front door is full range.

The rear speakers are full range and you can tap into the wires in the B pillars
