Make sure that when you hooked up your 4 channel amp to the remote turn on lead it is the same as the sub. Only hook amps to the Blue w/ white strip. The solid blue is power antenna lead and will lose power when on CD, ipod etc and only stays powered when the Tuner is on. Hope this fixes your problem.

Ive got a kenwood kvt-512 n im tryin to hook an amp n subs up but dnt know where to plug my RCA jacks from the amp 2 the radio!


Your unit should have 2 plugs in the back...one for the audio and power wires to connect to your factory connections and the other plug is just RCA connections for your video, subs and front speakers. If you have a 4 channel amp and a amp for your subs, you will have to split the 4 channel amp down to 2 and run them to your front RCA connections. Subs will connect to the sub connections. If yours are not listed then you may have to track down a wiring diagram. Hope this helps.

Yamaha rx-v2500 receiver how to hook up speakers


HI,

Follow these steps to connect a powered sub woofer to your receiver: You typically have two options when connecting a powered sub woofer. Input (1) on the rear of the sub woofer would be used when connecting the sub woofer to the receiver using speaker wires. You would then connect the main speakers to the opposite end, or output or the sub woofer to the main speakers. Option (2) would be using RCA line level output jacks, input (2) on the rear panel of the sub woofer directly to the single sub woofer output on the back of an AV receiver. blank.gif

I have a Fisher RS-909 Surrond Sound amplifier. It has no "sub out" jack. I had the sub-woofer working in the past by wiring it as shown in the manual. The problem is that the system was in...


Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

are you using more than one amplifier? it sounds like you may be using the blue wire to turn one amp and and the blue/white to turn the other one on. use the blue/white only. the blue wire is antenna remote and turns off when not in tuner mode.

I recently purchased a new Denon AVR-391 receiver and am having a problem hooking up my subwoofer. It seems that the Denon has a pre-out RCA looking output and my subwoofer uses conventional speaker wire. ...


Hi,
Your sub-woofer apparently does not have an amplifier built into it. This type requires you to use your front left and front right speaker output to got through it to your regular speakers. It is called a passive sub-woofer for that reason.
To set it up, Connect your front speakers to the "output" of the sub. It should say "to speakers" on it.
Then connect the Speaker Outputs for the left front and right front on your Denon AVR-391 directly to the Sub. It should say on the back of the Sub "to amplifier".
Here is some theory you should know, if you don't already know it, that will help you get a satisfactory result in setting up this system.
There is a condition on setting up all speakers and subs that not everyone know. It's call "phase alignment". Phase alignment (A Good Thing) refers to all of the speakers in a system moving in the same direction (in and out) at the same instant in time. This gives you much clearer sound and better response from your sub-woofer.
Phase Cancellation (a bad thing) is when some of the speakers are moving out and other moving in during the very same instant in time. It causes problems in sound.
IN A SUB-WOOFER, IT CAN CANCEL OUT THE LOW NOTES.
Here is how to handle it:
On the back of the receiver the speaker terminal outputs are colored Red and Black. Black is considered negative and Red is considered positive. On the back of the Sub woofer and on the speakers the same colors apply. MAKE SURE THAT ALL OF THE CONNECTIONS GO BLACK TO BLACK AND RED TO RED WHEN CONNECTING UP THE SPEAKER WIRES.
The system will work either way. But you will have severe bass loss if the woofer wiring is out of phase because of phase cancellation.
Hope this helps,
Best Regards,
Mark

Can you please tell me how to connect my kef psw


If your amp has a "sub out" jack, that's the best way to hook up this sub. You'll just need a single RCA (also called "phono") cable. Connect it to the Left input on the sub, which should also be marked as "mono"

If your amp just has speaker-level outputs, then connect the left and right main speakers from your amp to the sub's high-level inputs, and then run wires from the sub's high-level outputs to your speakers.

If you're running a surround-sound setup, use the front-left and front-right speakers for this hookup.


If this helps, be sure to hit the "thumbs-up" button for me!
If not, post back with the "Add comment" and I'll do my best to answer any questions you've got.

Hello i just recently bought alpine speakers for my eclipse 2003


mostly because the subs in the back are probley using more amps than the ones in the front in the front should be used mostly for vocals and your bass in the trun so maybe trying to unhook the ones in the front from the sub and just leave then hooked up to the cd player where you can hear the vocals really good and leave your subs in the back hooked up to the amp

Can't get my Accurian subwoofer to work


Sounds like you have everything hooked up properly. Make sure the outlet is providing AC power to the sub. Check the power switch on the sub.

If it is not working still; bring it back and swap it for another one before you warranty runs out.

SA-AX720 no subwoofer signal?


THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.
