You need to have either the high level or low level inputs connected to the head unit. low level will give you better sound quality, so i suggest using them if possible.

How to hook up the subwoffer


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.

Why will Amp not produce sound unless the input and output are patched together


A typical stereo receiver / amp consists of switching low level input signals (CD, DVD, Phono, DAT, etc.), processing them and then output to the amplifier (low level) input for amplification to levels needed to drive speakers. The low level signals would barely be audible via an earphone, so they need to be boosted significantly in order to drive speakers.

Some amps provide jumpers to insert into the phono jacks on the rear of the amp to bridge the processed low level output signals into the low level amplifier input. You could install a Y cable here to feed two amplifiers - or - connect a tape recorder's "REC L+R" to the low level output and the "PLAY L+R" to the low level amp input so that you'd hear the actual audio as it had been recorded on the tape.

If you remove the jumpers (or tape recorder if used instead), there is no way for the low level audio to get into the amp's low level inputs for amplification.

How do i connect subwoofer (canton movie 125 mx) to amplifier(onkyo txnr609)? there is one subwoofer output on the amplifier with either L & R(mono) high level input or L & R(mono) low level input...


Connect front the sub out (single) on the amp to one of the rca inputs on the sub, This will work reasonably well but to make the most from the sub buy a 2 rca to 1 rca cable and use it to connect both rca inputs on the sub to the single output on the amp

I want to hook up a slim sub for my truck using this amp. how can I do that? Because this amp plays everything not just the bass


You will need to connect the low level input leads from the head unit to the amplifier (they are RCA cables). If there are no low level leads from the head unit, you will need to connect the wires from the speakers directly into the high level inputs using a wiring harness which should have been included with the amp. It should include a wiring diagram. You will need to use that diagram in conjunction with the truck's wiring diagram in order to know which wires to connect. They are color coded and once you have the vehicle wiring diagram (which can be downloaded by searching for it on google.com), it should be easy to determine which wires to connect.

What wires do I hook up to the high level in plug that came with my dual xp2100 2 channel amp


First, know that you need either high level input or low level input, but not both. Low level input is preferred (RCA cables). If you must use high level input because your head unit doesn't have RCA jacks, you connect the speaker outputs from the head unit to the high level input of your amp. The high level input plug probably has a black wire, this is "signal reference ground". A pair of grey wires which are right positive (grey) and right negative (grey with black stripe). And a pair of white wires, left positive (white) and left negative (white with black stripe).

When I hook up the speakers in the back to the left and right side for the in and out, do I connect the front or rear speakers. do the speakers connect to the subwoofer first then to my receiver or the...


I was trying to find an owner's manual or picture of the rear panel of the sub, but had no luck. The subwoofer is a powered type - or "active" speaker. This means it has a built in amplifier. These active subs usually provide for one or both "low level" and "high level" inputs. Low level signals are usually carried by shielded coaxial cables and have RCA type plugs on the end. The low level is also called "line level". This is an un-amplified signal that might be heard on cheap earphones - but that's about it. It is similar to the output of a tape deck, DVD or phonograph. These signals require an amplifier to be heard. If you have a sub woofer output on your receiver or amplifier, you could run a patch cable between the low level input on the subwoofer and the subwoofer output of the amp or receiver. You receiver or amp may call this output "low frequency effects" or similar. The front and rear speakers would then connect directly to the receiver or amp's corresponding connections.

If you lack low level outputs on the amp or subwoofer, you'll need to run speaker wires from the amplifier or receiver's front left and right speaker output terminals to the subwoofer's high level input terminals. High level signals are speaker connections or amplified signals. These are typically connections that accept bare wire connections. The front speakers would then connect to the subwoofer's front left and right speaker output terminals. The rear speakers connect to the amplifier.

I hope this helps - and good luck!

Low volume through amplifier


Turntables generate a very low signal. Phono inputs on receivers containa pre-amp section to boost the signal to "line level" or the same level as other audio devices. I would suspect that you need to add that pre-amp section. Phono preamps are available for around $20 or so and are inserted between the turntable and the standard audio input on the receiver or amp.

Hope this helps,
Dan

I need to know how to install a Boss Audio


Hello viperman2004,

Just connect your speaker leads to the input of the B65N (gray and gray/white pigtail leads), run the RCA cables to your amp (red=right) inputs, adjust the left and right level controls to match the amp input without distortion, and mount the unit.

Hope this helps.

My klh subwoofer has R&L connections to speaker and R&L connections to amplifier, but my new amp has a RCA cable connection plug-in. Any way I can use the old subwoofer with the new system?


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.
