There are 2 sets of wires on the rca rt2760 home theatre system subwoofer, i know thay the purple ones are the speaker inputs......but the red and black is dc input for the amp thats inside the woofer,,,,,how much dc voltage is this? 12 volts???? who can answer this?

I will guide you through it.

Just to clarify, When you say sound out with the tv, which are you referring to:
1. DVD built into to the theatre
2. Pay TV
3. Analogue TV ( or digital TV with inbuilt set top box)
4.Digital TV with a separate set top box
Please indicate which one.

TV: ther should be several set of three RCA Sockets on the back of the tv. Look for the red, whit and yellow Phono sockets. do you have these colours and are any of them labelled TV Out or output?

Philips System: Look for an analogue in, Aux IN, or any other unused RCA (Phono) Sockets ( They MUST be red or white!)
Take a set of red and white RCA leads plug them into the OUT set on the TV, and The "INput" set on the Home theatre, select that input on the theatre and your off and racing!
Please clarify first though!

You can plug in higher ohm speakers , the higher the ohm the higher the resistance is, it is a danger when you plug lower ohm speakers into a higer ohm Amp , at a high volume that will cause them to blow , the center speaker would be fine to use a higer ohm speaker , your best choice is to buy a Active Subwoofer, which means the sub has it's own power supply , and u can blast the thing as much as u like , thn u can turn the bass down on all the other speaker's so u can play it louder , and have the sub turned up has high as u like , this is the best way to get great sound with high volume , buy a Active sub woofer , any active subwoofer is ok , a active sub woofer has its own volume and inputs on the speaker ,

have you tried infra red link?

Uhmmm. . .okay. . .I would use nothing less than 16AWG speaker cable. Do not run the speaker cable parallel in close proximity to any AC wiring. Speaker cable rated to run through walls with usually be color coded red and black. Connected the red to the red on the speaker and red on your home theatre receiver. Do the same for the black. If speaker cable insulation is clear, look closely for subtle markings or writing on the insulation. The writing will only be on one of the two wires. Designate that as the POS or PLUS or + or RED. Connected it to the red on the speaker and the red on the back of your home theatre receiver. The other is by default the black and connect it to like colors. Repeat for all 5, or 7 speakers in your theatre. Your subwoofer probably has a seperate amplifier, so it gets it's power from it's own AC power plug. . .so plug it in. The sound coming from the Home Theatre receiver will be low-power and will carry on an RCA cable. Look for the subwoofer output on the home theatre and connect it to the input on the subwoofer. There may be a right and a left input on the woofer. . .it doesn't matter which you plug it into. . .either one will do.

Does the Sub have a Low- Level input? This is a RCA type female connector, what you need to do is run a Male RCA cable from your home theatre where it says Sub-OUT and go into the Sub woofer Line in. Unless you only have speaker wire inputs on the back of the Sub then take the Left and Right front into the Sub speaker inputs and then out of the Sub speaker OUTS back to your speakers.

You cannot use this system with one that does not have a Subwoofer or LFE (Low Frequency Effect) output. Unfortunately, this sub doesn't have a line-level (speaker wire) input. Sorry.

i have just bought a DURABRAND SA51AR home theatre system, to go with my DURABRAND 2127N tv. and DURABRAND CG5660-M freeview set top box. i have connected all my output leads obviously the speaker ones. but my input i have only one red yellow white jack on my tv and three sets of red and white jack leads with home theatre system. cant get no sound no matter how many times iv swapped the input leads ... any idea s whats going wrong :oS :(

Well, I would have to know what connectors your sound card and home theatre system have. If you dont have a sound card, get a headphone/3.5mm trs plug to stereo rca plug adapter usually available at your local radio shack or walmart, and connect to the red/white rca plugs on your reciever. If they have other connectors(your sound card/ home theatre system) you might try coaxial digital audio-S/PDIF or optical S/PDIF.
