The product works great! Sounds good. If for some reason you find that your device and Amps will not shut off after the car or radio is turned off. Put a diode on the remote wire. It will then work perfectly.

used this to adapt my 2016 VW Passat with an epicenter and amplifier. Using the rear speaker outputs from the radio, the 12v + and the ground. it works perfectly. its small enough to hid right under the radio and ac control module. once you turn on the radio, everything turned on with no delay. turning off the radio same effect no delay in turning off. price was a deal. i recommend to anyone who needs to upgrade their automotive sound system and keep the factory head unit.

I got exactly what I ordered and it was exactly as expected. Package arrived early. Very Easy to install. Just follow the directions and look up your cars factory Radio/amplifier diagram to make sure your wire correctly (-) & (+) sides on both right and left channels so you can recieve the correct balance for your connection to your subwoofer amp. If wired wrong. Yoan test by switch the balance setting on your radio to right and then Left. If you hear more bass when you move stereo balance setting to right or left. Then one side of your recent wiring that you just connected from your radio to this product are backwards and will need to be reversed to get the proper sound. This product is a Great Product. It does its job. I will co ti ue to order more as needed.
