In 2019, GMC introduced a ground-breaking multi-function tailgate called MultiPro on its bread-and-butter Sierra pickup. And now, Chevy is launching the same tailgate under the Multi-Flex moniker on the Silverado. Both the MultiPro and the Multi-Flex are capable of six unique positions that help with using the pickup’s box. Additionally, both have the option of a Kicker audio system which allows owners to use their trucks as mobile concert venues, if they so desire. One common question that often arises from owners as well as those interested in this system is how it draws power. GM Authority has the answer.
The Kicker audio system in the Sierra’s MultiPro and Silverado’s Multi-Flex uses a low current draw from the vehicle which, according to GM, “allows it to play for hours”. Meanwhile, Kicker refers to the effect on the vehicle’s electrical system as being of “minimum impact.”
That means that one could use the Kicker tailgate system while idling the engine in order to keep the vehicle’s battery at optimum levels, but that sounds like a good way to waste a healthy amount of fuel. And besides, having the engine running while trying to play some tunes or listen to a live broadcast doesn’t sound like the best of ideas.
It seems reasonable to suppose, then, that Silverado and Sierra will have enough juice left in its battery to start up without any trouble after the stereo has been switched off. Switching off the Kicker audio system in either truck can be done by simply folding the tailgate’s inner gate step, since a tilt switch will sense then that portion of the tailgate has been folded. It’s worth noting that there should be no reason to do this prematurely, since the Kicker stereo is robustly protected from moisture and dirt, and therefore unusually safe in the hostile environment of a truck box.
The Kicker audio system is available as an official GM accessory. It’s priced at $1,249 for the GMC Sierra equipped with the MultiPro tailgate. Pricing for the system on the Silverado’s Multi-Pro has yet to be announced.
