Just bought a used Panasonic subwoofer & speakers. Do not see any input jacks, only a multipin cable plug ( no cable).

There are several methods, depending on the the types of 1)inputs on the subwoofer and 2) outputs on the amplifier (aka receiver). You can only use the type that is on BOTH.

Most sub woofers have "line level" inputs (they are the RCA phono style jacks or other style jack) that are marked "In" or "Input" and may have speaker level input & output terminal that accept speaker wires.

Amplifiers or "amp" all have speaker level outputs and many also have jacks that are labeled "Subwoofer" or "LFE" (low frequency effects) Output. If both your sub and amp have the "line level" jacks, then all you need to do is get a cable that is long enough to connect the two together, and then enable the low frequencies to be sent to the sub instead of the normal speakers in the receiver's set up menu. Done!

If you have only a speaker level connections common to both the sub and amp, you'll most likely need to disconnect the Main front L and R speakers from the amp and connect to the sub's Speaker Output terminals - and connect a couple of new speaker cables between the sub's Speaker Input terminals and the amp's Main front L and R terminals.

If you don't understand completely, provide the make and model of the amp and the sub, and I'll be able to clear up anything that isn't clear.

There are a number of amplifiers in the TA series, but the connections are basically the same.
In your system, the amplifier serves as master control. How do you know? Look for the component that offers input selection -tuner, cassette, CD, video, phono and probably auxiliary. Every other component plugs into and is controlled by the integrated amplifier. For example, plug the tuner wires from the tuner output to the amplifier input marked "Tuner." To use the tuner, just select that input from the front panel. Same with all the other components.

On the back of that unit will a bunch of RCA jacks for left and right channels. Take the hook-up wires, usually RCA cables with colored plugs on each end, and connect the OUTPUT jacks on each separate component to the INPUT jacks on the amp. Power may also be controlled from the amp. On audio plugs, red is right and white is left. Keep the polarity constant as you connect each component. Connect the speaker wires to the speaker outputs, usually spring clips or screw terminals on the amplifier end and the same on each speaker. The DVD video cable will have three wires: Yellow, red and white. Yellow is always video. It may also have a little round video connector for S-VHS which provides a much better picture when using DVD.

Just run an cable (3.5mm headphone jack into stereo rca cable) from your ipod's earphone jack to one of the available input channels on your amplifier. I put mine into the front auxiliary input on my amp and just simply selected that channel on the amp. Hope it helps. By the way, an RCA cable is the one with the white and red plugs.

The only digital audio input for this TV will be via the HDMI input. Of course, even with HDMI in, you're only going to get a simple stereo output from the TV. You can use the analog L & R audio inputs for a very similar sound from the TV speakers.

The digital multi-channel audio (Dolby Digital, THX, 5.1, 7.1, etc) encoded in the program should be connected to a suitable multi-channel amplifier with either a TOSLINK (optical), RF (coaxial) or HDMI cable for theatre-like sound. This can be done by (a) cabling from the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) directly to a multi-channel amp and speakers, or (b) from the HDMI output of these devices (DVD, BluRay Disk, Set Top TV Tuner, etc.) into one or both of the TV's HDMI inputs. This will provide only stereo sound output from the TV speakers. You should connect the TV's TOSLINK optical "Digital Output" jack with an optical cable to the amplifier's TOSLINK optical input jack to obtain theatre sound.

To listen to the program shown, you would select the amplifier input assciated with the optical, RF or HDMI input that is connected to the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) if connected directly. If the TV HDMI input(s) are used, they are output to the TV optical output and should be connected to the amplifier optical input. The amp input associated with the optical input should be selected to hear the program with theatre-like sound.

As I implied earlier, take a clue from the physical style of connectors for both parts of the subwoofer function in the old and new receivers:

RCA connections are for Line Level signal between components only.

The input (bare wire) at the speaker is for AMPLIFIED signal.

You can't just modify one to fit the other and expect magic to happen. Be glad you didn't do it the other way around and modify an amplified (speaker level) outout into a Line Level input. You likely would have smoked that component.

Your subwoofer is a passive speaker, that is, like any other speaker it needs an amplifier. Many subs are self-powered (amp built-in) and they would mate well with the RCA sub output of the receiver.

Get yourself an Active (self-amplified) Subwoofer and run UN-MODIFIED RCA cables to it, according to its instructions, from the Sub Out of the receiver. Or get an amplifier between your receiver and the sub you have.

On the back of the amp, there should be a jack with the name "SUBWOOFER PRE OUT". It is a standard RCA jack, but it only puts out a line output, meaning only self-powered subwoofers will work with it. Usually, if the subwoofer does not have an amp, it will have 2 imputs and 2 outputs. You plug the two left and right inputs into the front speaker jack on the amp, and then plug the front speakers into the left and right amp on the subwoofer.

Do this, CD audio out jacks to the PRE-AMP INPUT jacks, then PRE-AMP OUT jacks to AMPLIFIER INPUTS then from AMPLIFIER to speakers, This will work similiar with any sound source unit ie. Radio Tuner, Tape deck, etc. Just think of it this way, a PRE-AMP is BEFORE the AMPLIFIER, all the AMPLIFIER is going to do is AMPLIFY the sound to your speakers, HOPE THIS HELPS!

Yes, you use a subwoofer cable and hook it into the mono rca jack in the back of the sub. or you can use a Y splitter 1 female to 2 males. or if your amp has 2 sub outputs (L&R) then use both. I do believe it's said that if you use the high level input, it's better. I forgot why...

Oh yeah. the difference between the 2 is a high level input allows the currant from the amp to pass through the sub, thus allowing the continuation of wattage to your other speakers.
Low level input is only taking a audio signal from the amp. No power is being sen through the connection.

you will need to buy a newer style cd or tape player with jax on the back
