Question:
RCA connectors behind head units?

With the connectors behind Car audio head units. The really good head units come with six female connectors (Front, Rear and Sub). Now with the front and rear are you able to use male RCA connectors combine the 2 front speakers, wire both positive from the fronts in to one male connector and both grounds from the fronts in to another male connector. Same with the rear. Or do you still need to use the wires that came with the head units to wire the speakers. I know power wire and ground and Alt wire have to be used but does the speaker wire have to be used or can you connect the speakers straight into the headunit RCA Female ports with Male RCA Connectors. Just a wondering Thought

Thank You,

No, you must still run them to the speaker wires... The RCA's just send sound signals to amplifiers so they know what sound to send to the speaker... But the RCA's do not send an amplified signal like when you hook up the speaker wires the regular way.

I'm not sure I understand your question.



RCA outputs are only used to connect a low-level signal to a separate amplifier. Speaker outputs are meant to be connected directly to speakers. You can't "bridge" or mix the speaker outputs; each speaker output pair should be connected to only one 4-ohm speaker. If you're using a separate amplifier or multiple amps to power your speakers, you do not need to use the head unit's speaker wires at all.



You definitely should not connect RCA outputs directly to speakers, or combine the separate outputs into a single lead. You can use Y-adapters to split the outputs if you're running multiple amplifiers.



A higher pre-amp output voltage is useful for a better signal to noise ratio; if you have a higher signal voltage coming into your amplifier, you can reduce the gain control, which also reduces the background noise that may be picked up in the RCA cables.



You don't need a separate amplifier for each speaker (although you can do it this way if you want). That's why multi-channel amplifiers exist: a 4-channel amp could be connected to the front and rear RCA outputs, and drive four separate speakers. You can combine a 4-channel amplifier with a 2-channel or mono amplifier for the subs; or, you can find 5-channel and 6-channel amps. (A mono amplifier generally takes a 2-channel RCA input, and combines the two channels into a single output).

as long as you're beneficial there is not any inventory amp or some variety of filter out (crossover) feeding the 6x9" there must be no undertaking. The aftermarket amp needs to work out an entire selection sign to be effectual in it quite is frequency selection exceedingly if it is going to a sub and the 6x9's are severe handed. If there's a inventory amp then you definately will could desire to faucet into the enter wires feeding the inventory amp so the aftermarket amp won't see too severe voltage that the speaker point inputs can no longer cope with. the two that or deploy a line output converter designed to cope with the greater effective wattage.

i would suggest looking at the decks manual weather if you have it on paper or online and if you have an amplifer do the same.



rca is called low voltage signal while the speaker wires are high voltage and do not match.



you said alt wire, do you mean acc wire, that is a switched wire when you turn on the car.



do some google and check out this site. and re-ask this question or e-mail me if needed.
