    Very easy to install, does exactly what it claims to do, holding up nicely. Used to tap my rear speakers in a factory system to add rca outs for an underwear sub. Definitely worth the price.

    [Employee of bestbuy] Its nothing fancy with tuning but does the job right to convert a signal to AV. The remote turn on feature is a must for simple install where you dont want to wire more cables across the car.

    Installing installing an aftermarket app in my twenty sixteen nissan titan x d platinum reserve. This is a very simple product to use that gives you. The option to use an after market amplifier . Simply connect the speaker wires to the product from your vehicle ground. A groundwire from the product to the vehicle. And you ready to go? It literally takes 4 minutes 5 minutes to connect this product. If you know exactly what you're doing and I hope you do.

    Works as expected. The remote feature really shortens the install time by allowing me to skip running a remote wire from the fuse box to the amplifier. Great feature!!
