What wire do I plug in for the subwoofer cause I I have read cables but there's 2 and I only have 1 connection for the sub on the back of the stereo


This subwoofer is probably powered directly from the amplifier and doesn't have an internal amp. The connections are probably the same type as for any other speakers. And, there are probably additional connections for the rest of the speakers. The connection on your amp is likely an RCA phono plug connector that sends low level signals to a powered subwoofer. To connect a passive subwoofer, one without a built-in amp, the main speaker outputs connect to the subwoofer and are then sent to the regular speakers connected to additional terminals on the subwoofer. You may need an owner's manual for the subwoofer to determine how it should be connected.

The Fusion EN 6001 amplifier has two channels with screw connectors and also two channels with phono sockets labelled "output". What are these two for?


The outputs are for RCA connection(line level output) to a second amplifier.
Not sure if exact model but here is a link for a manual that will explain in more detail:

Im trying to hook up a paradigm pdr-12 to my tv and xbox 360 and need an idea of how to do this the right way so it only plays the bass and nothing else


Hello there this subwoofer has a built in crossover variable from 50hz to 150hz which means that any signal you feed it the sub it will ignore anything but bass anyway.

As for the connection it is made quite difficult if you don't already have an amplifier powering your other speakers, usually home cinema amplifiers have a low level pre out for subwoofers, for which you would just need a phono to phono cable.

However if it doesn't and you have any type of amplifier with at least 2 separate left and right speakers you can connect the wires from these into the subwoofer and it will output the bass from these 2 channels.

Another option is to use a mono to stereo (2 to 1) phono cable where the 2 connectors at one end connect to a tape or record output on your amplifier and the single phono at the other connects to the subwoofer, the same would go if you have a red & white phono (RCA) output on your TV you could also use this to power the sub, in the worst case scenario you could use a single to single phono or rca cable to connect one of the output channels (left or right) on your TV to the subwoofer however this would mean that the subwoofer would only output bass from either the left or right channel.


Hope this helps


Kind Regards

Hi i have just bought a alpine dvd headunit the 105r and it only has 1 phono sub output and not the left and right phono output how do i connect my amp to this


it has 3 pairs of rca outputs, one pair for the front, one for the rear, and another for the subwoofer. the other sub preamp output is not needed to run to your amplifier.

For better sound quality, buy an RCA Y splitter cable (single male connection to double female connections), and run your regular pair of rca cables to the amp.

Receiver cannot recognize subwoofer


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.

Connect subwoofer etc to nad 3020I stereo amplifier


Hi Info
You can use a 2 x male RCA to RCA female adaptor lead(what you need to ask for)  like this one 4d0dcde.jpg

use it to jumper your pre-out/main in connection on the rear, and connect an RCA lead to the Female socket on the adaptor lead. That will get you going. You can get them most places that sell electronic bits and peices. I am happy to answer any questionsa you may have

Instruction manual for ministry of sound mixing decks


What are Ministry of Sound mixing decks? I am familiar with MOS, but was not aware they manufactured mixing decks?

Are you connecting these to a DJ mixer, or a Home Receiver?

If it's going through a home receiver, make sure you have them connected to the PHONO input on your receiver. If your receiver does not have a phono input, and you are connecting to the LINE IN or AUX IN section on the rear, you will not hear much. Most turntables require a pre-amplified signal, and only the PHONO input has this option. So, you will need to purchase a PHONO PRE-AMP, and connect your turntable to it, then connect the PHONO pre-amp to the LINE IN.

If you are connecting to a DJ mixer... same thing. Make sure you have them connected to the PHONO INPUT on the mixer. If you still don't get anything, then there might be something wrong with your mixer.

If you could clarify you exact set up, and the EXACT models, we can help you better.

Low Audio


You need to connect the turntable to a PHONO input on your amplifier. Not all amplifiers have a phono input, if yours doesn't you need to get an RIAA pre-amp to plug your deck into & this connects to your amplifier.

This is because although the audio outputs on the turntable look the same as all the other components, they are very different. The signal has not been amplified up to line-level like tuners, CD players, tape decks, etc. You need to get this thin, weak signal boosted.

Your 3 options are:

* Connect directly to the PHONO input on your amplifier if you have one. If you don't:
* Connect deck to a RIAA amp (also called a phono stage) then connect to any input EXCEPT phono on your amplifier
*Connect the deck to a DJ mixer then hook the mixer up to any input on the amp EXCEPT phono.
