Hi all,

In the process of installing Hertz D4 Amp into my car using the High Pass option as the OEM headunit doesnt have RCA. The manual says i don't need to use the remote switch but without it, it wont turn on. And so I've connected the cigarette lighter, and its now turning on. But, it wont turn off now. Even after locking the doors, it is remaining on and I can see that its also keeping some of the interior switches lite up which doesnt normally happen.

When connected the speakers are also hissing.

Thanks in advance, all suggestions welcome
