Can I splice a non-phono subwoofer plug into a phono connection to plug into a home theater receiver?

Question

I have a 5.1 speaker system with a non-powered subwoofer. I am looking to purchase a newer home theater receiver but most of these receivers have what looks like a phono/coaxial plug for subs. Can I splice the wires of my sub into a male phono jack to plug into this?

Answer 1

The reason the new receivers have that kind of output is because newer subs have an amplifier built in. If you really don't want to replace your sub you will have to replace the amplifier that was powering it. (it was built into the system receiver you are replacing) The newer receivers don't have a sub amp so you can buy a separate amp but you will be better off buying a powered sub. Your last option is to share power from the front left and right speaker output, easily done if you have A and B outputs on the new receiver, however, I am guessing your sub only has 1 speaker input (as usual if it is a Home Theater in a Box with unpowered sub) If so that's not going to work. Connecting just one will unbalance your sound and produce base irregularly. connecting both will cause huge problems and probably damage the receiver.
Essentially the sub you have is designed specifically for the system you are replacing. I would replace it.

No, you're able to not plug the rest different than a turntable into the phono jacks on your amp. aside from the enter ranges and impedence issues, there is one greater significant difference right here. The records have been/are made with an equalization with the intention to shrink bass (low frequencies). the reason at the back of this is that low frequecies demanded somewhat some needle circulation interior the groove that's complicated to fabricate with out errors and consumes somewhat some area too. lots of the phono inputs have been meant for this and so aside from boosting the enter ranges in addition they greater the bass ranges and now and lower back decreased the severe frequencies. you're able to not plug something different than a turn table into the phono enter. despite the fact that there are some amps that merely have an enter named phono yet on the comparable point as different inputs and those amps run turntables with an extremely expert pre-amp for turntables. If yours is this way, that's going to likely be reported someplace. in case you have not have been given any techniques, terrific may well be to flow away the phono on my own and use it provided which you do have a turntable (in spite of transferring magnet or transferring coil style cartridge).

Answer 3

No.

The RCA output on most receivers produce line-level signals.

Your un-powered subwoofer needs WATTS of power or 'speaker level' signals.

Here is how you hook it up:

- Run speaker wires from the L/R speaker outputs to the sub. The sub should have speaker wire outputs that you run to the L/R speakers.

The sub will strip off the low frequency sounds and pass along the higher frequency sounds to the speakers.

Answer 4

You can, and it will work, but can your amp handle it? Also make sure you maintain the correct polarity.
