An input for a fitness tracker could be it recording you heart rate because it is inputing that information
I'm assuming the headunit has 2 sets of RCA outs - Front and Rear. If so, then one of your amps will need to have RCA outputs(sometimes called pass through) as well as inputs. Run an RCA cable from the "rear" outputs on the deck, into the inputs of the amp that has outputs. Now run a cable from the outputs on that amp to the inputs on your sub-amp.
With a line output converter. Converts high level speaker outputs to low level line (RCA) inputs. Raptor install accessories part #LOCA25.
NO there is not.
A two channel amp, in simple terms, means that it amplifies two different inputs channels (left and right usually, or could be front/rear), and outputs them into two different channels. Other types of amps you may run across is a one channel amp, which again amplifies one signal or channel.
nope... ;(
Your amp should have connections labelled as "high level" or "speaker level" inputs, or something to that effect. If it does, then you simply run the speaker wires to these connections, then run the outputs to the speakers. (obviously you still need to wire the power, ground and remote turn-on to actually power up the amp)
Yes, provided that your amp has line level inputs, and you have the appropriate adapters.
Red and Yellow
Yeah but the amp has to have 2 active inputs and there are few amps that have 2 active inputs You need a 6. 5mm cable splitter. . . These have two 6. 5mm female input sockets (same as guitar amp) and one male output. This means that you can plug two guitars into one amp!!!
yes they are high level or speaker outputs anywhere in the 3 to 15 watt range if they were low level they would have insulated rca outputs. depending on your system they can go into a factory amp and boost the wattage or just go straight to speakers most have booster amp
high level inputs
There should be a "signal out" from your board. Monitor send, effects loop. Any number of outputs from a mixer you could use to run another power amp and speakers. Some power amps have a signal out line. Do not hook the speaker outputs to another amp unless you like smoke.
