If you only use the white or the red then you won't have the correct sound so i would say buy a new deck but if you must get a "y" adapter but your bass may not sound right.

When input my 3.5mm jack to my audio input port on my face-place, my sound goes to my left side. However when i pull out very slightly on the jack, it goes to stereo, but i have to hold it there to keep it...


Try reversing the cable and see if one end fits better. Or buy a new cable. Also some aftermarket car cd players have RCA inputs on the back or cd changer inputs too, which can be changed to RCA input style connectors with an adapter. Then you will need a 3.5 mm to RCA adapter. You just need the RCA to 3.5mm adapter if you have RCA inputs on the back of your cd player. then run your 3.5mm wire from behind your dash to an accessible and convienent area. I ran mine into the glovebox in my car. My deck had RCA imputs so I just ran a long RCA cable into the glove box, put the 3.5mm RCA adapter on that, then hooked my iPod 3.5mm wire up to it. Now it's hidden and easy to store out of sight, plus with the extra long RCA cable to 3.5mm setup anyone in my car can have the iPod and change the songs. Hope that helps.

Do not know how to connect my kappa 60.5cs to my pioneer cd player do they have to go through an external amp?what do i do with the power plugs on the oppisite side why are there 2 per speaker


You need to run RCA cables from the CD player to the CD or AUX input on your amp / receiver unit. If you have a standalone amp, you need some way to control the volume. Basically, if you have a volume control on the front of your amp, you're OK. If not, you should also have a preamplifier that the CD player feeds first.

From the amplifier, then, a single pair of speaker outputs feeds a single pair of inputs on your speakers. The reason for two jack sets on the speakers is for "bi-wiring" or "bi-amping", not necessary for basic stereo reproduction.

So -

CD red/white RCA out -> preamp/receiver red/white CD/AUX input. Amp speaker output (red + / black -) to one red/black input pair on the speakers. An input on the speaker is side by side...

Keep the red to red, black to black when connecting the speakers, or you will wind up with poor sound and weak bass.

I have a kenwood kdc-w3541 cd player and would like to wire it to a 4ch amp can you tell me how to wire it....thanks


Your kenwood only has preouts for a subwoofer. If you want to add the amp the amp will need to have some high inputs. If it does not then you will need to buy an accessory that will allow you to connect speakers and have rca outputs. From there yo will need two sets of rca jacks to run to the amplifier.

My kicker zr240 powers up but its no sound coming out the amp the guts of the amp looks fine


it could be your input section on your amplifier were you rca jacks go in but you should check and make sure it aint your cd player out put on your rca jacks the easy way to check this is with a meter and a cd playing in your cd player turn your meter on volts usually your out put on rca 2.5v some cd players put out 5v so take your postive tester needle and stick it in the inside part of your rca jack and take negative tester needle and touch the outerside of the rca jacks and see if you get any reading if do that good on that part but on your amp no it could be in the input section of your amp it could be as simple as a burnt trace wire on the bottom circuit board or a op amp chip theirs alot in a amplifier but you can test them with a meter to find out witch one bad but i would take it to some one that work on amplifiers if you dont know how to test them

No Soound on Subwoofer from Yamaha RX-V363


I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

Jensen cd 2610 aux input has little volume


first of all the rca jacks in the back of your radio are for plugging in an amp, not your mp3 player. there should be an auxiliary jack(looks like a headphones jack) in the front of the head unit. if there is no auxiliary jack in the front then you will have to go buy a new head unit with an auxiliary jack.

Brookstone Wireless Outdoor Speaker with Bose 123 System Problem


AUX usually refers to an INPUT, such as a CD player, etc. No signal comes out of a standard AUX jack, unless it specifically says "Aux speaker output". Instead, look for another speaker output jack, such as remote speaker, B speakers, etc. You may only have one set of speaker output jacks, in which case you would need to connect your wireless speaker to the speaker output jacks along with your main speakers, or buy a little speaker selector switch box to switch between main and wireless speakers. There's usually no harm in connecting more than one speaker set to the same outputs, though it is technically not recommended. In the real world, just don't crank it too loud and you'll be fine. The wireless speaker MIGHT run off of a standard line output also, if the wireless speaker has its own power amplifier.
