Question about Panasonic MXE CQ-C7401U CD Player

Subwoofer Output Not Working...

I've had this deck for about a year, everything has worked well. I have subs hooked up to the RCA sub output connectors to an amp and 2 10 inch subwoofers. I removed my subs to put somthing in my car, put the subs back and now I hardly get anything out of the subs. I took the subs and amp into a shop and verified they are working perfectly. I even hooked my ipod up to the amp and it worked fine. The amp powers up and everything, and only a little bass comes out. The shop said it is probably the deck that is the issue, has anyone ever had this issue? Everything works find except for that! It sux! Thanks for any help!

That is what the tech did down at the store and said it was a no go, that is why he hooked up the ipod and the subs bumped hard...

I'm in denial about it being the deck just because I know it will warrant a replacement :)

I did this and it worked, but loosing the sub woofer volume control is a bit of a downside, but it will be a good workaround until I can aford another unit...

How strange that the subwoofer outputs would just fail like that...

Is there any sort of a reset procedure that I should try with the unit in case somthing is hung up in the software side? I've already removed all power from it for about an hour.

The first thing to try is disconnecting ONE of the two subs. See if you get more bass with a single sub than with both. If you do, re-connect the second subwoofer, but reverse the (+) and (-) wires.

You can try switching the RCA to the deck's rear or front output instead. The subwoofer amp should still work from one of those outputs; you just won't be able to use the built-in subwoofer volume control.

If that doesn't work, you might try substituting a different set of RCA cables. The problem may be in the cables and not the deck.

How to hook up emerson subwoofer sw 03

For powered sub :If your receiver has a sub woofer output on female RCA plug, that is the way to go. If no output you will have to get a speaker line to line output converter to then connect to your subwoofer amp input.

Unpowered sub - just hook up across the speaker terminals for each channel making sure that you hook it up in phase.

Problems with JBL PSW D110

The speaker level input option is designed for receivers that don't have digital output for the sub, used this way when you set to digital the speaker outputs only get the higher range outputs so won't reproduce much bass. To get the sub to work in digital mode you need to use the digital output (single RCA) from the amp to the sub

You can prove the sub pre-output works by running an RCA cable from it to the input of a tape deck, TV or any other device that accepts Line In and will either display it or play it. Test it on VERY LOW volume at the receiving device.

Different sub pre-out cable?

Does the sub work at all? How is it hooked up? The sub needs to be fed by an RCA cable from the Subwoofer Output jack for the receiver to control its output.

I am trying to hook up a powered sub woofer to a yamaha rx-v461 and i dont know what cables go where on the back of the sub there are two speaker ports and there are two plug ins but each speaker port has...

Your subwoofer probably has both high-power inputs and "normal"low inputs. The first are for receivers, which don't have link-level output for sub, so they are able to take already amplified signal as input.
You need to use link-level input of your sub and connect it to subwoofer-output of your receiver. The output is marked as OUTPUT - Subwoofer and is black-color RCA plug (don't confuse with subwoofer INPUT under MULTI CH INPUT).
Receiver has only mono output for subwoofer. If your sub has stereo input (white/red RCA plugs), connect just the left channel to the receiver, it will still work.
Don't connect anything to the speaker output on the sub, you don't need that.

I have a kenwood head unit with 3 rca outputs,front,rear and sub.my crossover is a kicker kx3 and it only has front and rear in and front,rear and sub out.my question is how do i hook up the crossover...

No. I would recomend running front and rear to the crossover. Use the sub out on the deck so you have total control of subwoofer output at your fingertips. Your deck should have at LEAST an 80hz crossover built in. Any further fine tuning can be done at the sub amp.

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.

Subwoofer to receiver hookup

In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs.
Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.
