How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...
:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..
Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..
Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..
for example a basic music system is
1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)
you bridge 1+2 and connect this to 1 12" double coil sub woofer
the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..
Thats a kicking tricked out basic car audio system,,,
Hope that helps you understand how it works..
