Very small so easy to fit behind the dash, clear instructions, worked as described using speaker wire as the trigger. Just one note: The 6 volts DC that is present between the speaker output on the factory stereo and ground stays on for about 30 seconds after the radio goes off. Also it will turn back on when remotely unlocking the doors. It will turn back off again though if you don't start the car. This has not caused any problem and seems to be normal operation of CAN-BUS systems in newer vehicles.

This was purchased due to researching the audio upgrade in a 2011 C6 Corvette with the Alpine iLX-W650 head unit. Due to the Vette parking brake on the operating performance on the Alpine iLX-W650 head unit, this chip will send a signal allowing head unit to work to its best performance without moving the park brake lever up and down numerous times. This was soldered into the Alpine iLX-W650 head unit harness and not on the Corvette parking brake wires. This is just to keep the issue pretty clear!!!

This product is advertised to eliminate the popping noise when the amp is shut off and it doesn’t work. Amp still pops when powered off. Very disappointed indeed. Works as a remote turn on just fine but doesn’t block the popping noise.

Used this when the amp wire wasn't working for my head-unit so that i could use another acc power.Works exactly as it should, my subwoofer doesn't pop when i turn on the truck.Note one thing for me: It does not reset instantly. So if you turn it on and turn the signal off and then back on again it quickly, it will not time delay. This is due to its design which is how any delay using a capacitor is going to work.

It does not operate properly when input signal is low. It may be OK for amplified application.

Worked perfectly for me. I wired an amplifier and new speakers from my factory head unit which does not have a remote wire output for the amp. So I purchased this to act as a remote signal. I connected all of the power leads directly to my amplifier and then spliced the blue wire into a pre-amp speaker wire. Now my amp turns on when the radio turns on and there is no more loud pop due to the delay.I would highly recommend this to anybody without a remote wire on their head unit.

As other reviewers have noted, this product did not work to bypass the parking brake signal on a brand new Pioneer AVH-2550NEX stereo that was purchased from Crutchfield. After watching some youtube videos of the product being installed and working on a Pioneer deck i ordered it from Amazon. Unfortunately the product did not bypass the parking brake signal and so will not display DVDs. I just went with the switch option. Returned this product within the return window and Amazon gave me my money back.

Su funcionamiento no tiene queja. Solo podía conectarlo al negativo de la bocina de un canal trasero y es suficiente para que ponga en marcha el amplificador con 2 segundos de demora. Se supone que es 1 segundo pero el mio da 2. Solo se apaga cuando apago mi estereo (HU) o saco la llave del encendido. Gracias a esta cosa me ahorré cablear el encedido remoto y siento que hasta el ruido del alternador desapareción (a lo mejor solo me acostumbre).He notado que, aunque los productos de PAC son feos, realmente funcionan muy bien.
