None of our line converters or processors put a resistance on the outputs of the factory system/amp.
A lot of newer vehicles factory systems MUST see a resistance on the outputs in order to work properly.
If they don’t see a resistance, there are a number of different ways the system may react.
The most common is that it will not output any signal at all. Or, it may output distorted signals, or will send random noise to specific channels. The worst case scenario is that the amp will see no resistance at all and it will just send all of its power out all at once, which typically results in burning up your after market amp.
The work around for this is to put resistors on the inputs of the line converter.
