Review on 🔊 Upgrade Your 2010-2019 Toyota Tundra Factory Amp: AutoHarnessHouse.com AHH-4438 by Eric Ross

Worked great on a 2019 Toyota Tundra with a factory (non JBL) amp. When connected directly, the length was sufficient to connect the new JL Audio 400/4. I read other reviews that said this was not properly fixed for their Toyota. Not sure how it is, Toyota uses the same pin for all vehicles that use this connector. This product offered both a high level input for my JL amp and a speaker output. It also has a useful remote control. The connector has a 12v pin and ground but these are not used on aftermarket amps as they are unable to deliver the correct amount of current.
