I have a 2007 Acura MDX. I added an amp and speakers. The line out converter I used had a remote turn on feature that began to malfunction. It always gave me a pop, but began to pulse my amp. After installing this at my amp and changing the wire to signal it to turn on, there is no more pop or pulsing. If you plan on adding an amp to a factory radio that doesn't have a soft turn available, then this is a must have for your installation!👍

The module it works great. I don’t have the popping noise when I turn my motorcycle on. Before adding the module, it was irritating to listen to the pop sound. That was every time I powered up my system. Major difference and I love it. It also reduces feedback thru the speakers while riding the motorcycle too.

This product worked perfectly for me as a remote trigger using the speaker output on a factory head unit as the low voltage source. It's nice that the amp now powers off when the radio is powered off.

The downside to the TR4 is that it won’t work with many newer factory head units. On my car (2017 Civic) there is a small voltage present in the speaker wires any time the car is on, whether the head unit is powered on or not. This tells the TR4 to send power to the amp, so there’s no way to get it to work as intended in my car.

This is a good stuff for European cars, remote turn on.
