Did an install for a kid on a '05 accord, Owner wanted to keep the stock radio so I wired up the remore wire to the Tantrum1200.1 to the ignition lead. Worked great both L7 sounded good, but could have been wired for better use of the amp (subs were prewired by another person). So we bump and bump and bump he happy, we turn off the car and the key wouldnt come out, LOL we are thinking WTF? Turns out the factory alarm/ security didnt like that I tied into the harness for the ignition. So, we drove around and had to disconnect the battery if the car was sitting, he got it fixed within a few days I will never do another install on a NON american car again
