Thread: RC out of factory head

In fact, many amplifiers include differential inputs and a high-level signal can be used on the RCA inputs. The input sensitivity control will have to be turned down, though.

Here's how to tell if your amp is capable:

1. look at the CEA 2006 rating for maximum input signal voltage. If it's better than about 5V, it'll be ok. 6V+ is better.
2. Use an ohm meter to be sure than none of the RCA shield connectors are continuous to each other or continuous to chassis ground.

If your amp meets these two criteria, you can safely connect the speaker outputs directly to the RCA inputs. The benefit of this arrangement is tht the signal will be completely isolated from ground and the input voltage is higher than using RCA outputs. That means NO NOISE.

I guess you have it working. But it would have been nice to know you had high level inputs from the beginning. Which makes me wonder why you wanted RCA connectors? You could have ran speaker wire from stereo to the amp. The amps I've seen with high level input have a connector with the input wires and not RCA connectors.

Oh well welcome to the forums. More info from the start next time

well that's not what you said earlier. you said "I just spliced a couple of females into the speaker wire, and ran rca from those leads to my amp "...

if your amp has high-level inputs they will be in a wire harness/connector, not RCA inputs. RCA inputs in amplifiers are only used in low/line-level inputs.

your statements contradict each other. what exactly did you do? :?:
