    The ACC source is retained even after I turn off the engine, until I open the door or the battery goes too low voltage or a certain time (IIRC 10 minutes?) is passed. It's data controlled by the CAN...

    Hi guys,

    I have a TDA7850 which I believe draws less than 1A on average for my setup (as I mentioned earlier in this thread). I heard from many people that the amp should be attached to the...

    The wires are actually closer to 20AWG than 18AWG.

    Thanks very much for your information. So I also need to measure the actual current the amp draws at *different voltage*.

    Hi OldSpark,

    Thanks very much for your detailed information. Now I just learned the divide by 10 rule.

    Just tested in my car. I can't tell there's any difference in terms of quality from that of the stock radio. Honestly, it's not too bad considering its price. The only complain is that the 2.5mm...
