For those of you looking to setup your own MultiPro tailgate speaker system, well HERE YOU GO! Wiring harnesses and amplifier brackets to make your project super easy!! No splicing or hacking away at your expensive factory wiring! I have a limited number of the items in stock, 10 or so of each, with more that will be ready next week!

When I did mine, I used the Soundstream ST4.1000DB bluetooth amp (and I am very pleased with it so far), so all of the options are available as plug and play with that particular amp. Or you can just get a harness with a pigtail that will give you 12v+ power and ground in your inner tailgate, so you can wire it up to whatever you want. Don’t forget to check out the options for adding lights and the speaker wiring harness to make the whole system truly PLUG & PLAY. so much better sound than the Kicker system for a lot less money!

All items come with complete installation instructions (with pictures, ha)!

Let me know if you have any questions!

nice design, nice website, good job!

One thing I couldn't notice in the wiring harness, is there an on/off switch?

Thank you!! 
 

there is not an manual switch but there is a tilt switch integrated into the harness that automatically powers the amp on (but doesn’t automatically play music) when the inner gate is fully deployed (down) and automatically powers it off when the gate is folded up. A manual switch could easily be added if someone preferred that. 
 

let me know if you have any other questions!

Do you have a picture with the step closed to show clearance?

The step easily closes without the speaker grills, but I wanted the grills on so i stacked some fender washers in under the step and grabbed some longer screws from Lowe's.

Edit: duh you said pictures and instructions are included.

 

next dumb question, does the accessory power need to be on? This is my first sierra and i'm not sure if the trailer power is on when the vehicle off.

The truck accessory/switch does not need to be on. The trailer power is always hot, hence the need for the tilt switch.
