Spring clip to Phono

I currently have a Panasonic Home Cinema system, containing the SA HT855 DVD player/Amplifier, all connected to the supplied loudpreakers by spring clip connectors.
I wish to replace the passive subwoofer, with a Yahama YST SW205 active subwoofer.
The problem I have is that the amp has 2 x spring clip connectors, and the Yamaha has 2 x phono inputs.
I have tried to cut of one end of a phono connection, srip it back and clip it in, but this results in a very loud hum.
Secondly I have tried bell wire clipped into the amp, and jammed into the Yamaha with phono plug, this time no hum, and more to the point no sound.
Can anyone help?

Have you though WHY! does my AV system use a passive sub and an active one does not work?
The sub output on your AV system is a power amp output not a sub pre-out that then uses the subs power amp. If the sub had loudspeaker input terminals (High level input) then you could connect it to the Speaker outputs on the av system.
To drive that sub correctly you need a REAL AV amp with sub (pre out).

The reply above is mostly true, tho not exclusively.

You don't NEED an AV amp, though it would bring several benefits. You could alternatively use a subwoofer with a high-level input (such as a REL or BK, tho there are others) that will accept your powered output.

I am slightly worried that you may have damaged you sub, as it will have been expecting a very low level 2V signal, and you've been sending it a much higher voltage and current. The fact that it has ceased humming could well be a sign that it is damaged. :(

:rotfl:

Sorry I know I should be trying to be helpful here but this has to be a wind up?

If not that I am gobsmacked you would expect something to work by 'jamming' wires into quite obviously incorrect connectors. If you haven't fried your system or your Yamaha subwoofer already then I suggest you refrain from further shinanigans before it costs you a lot of money.

There is usually a very good reason for differing connectors on different equipment. For instance hammering a BT phone plug into a standard mains socket is unlikely to improve telephone reception.

I suggest a little research on the forum would be useful as there are plenty of helpful people who can point you in the right direction. However it would appear that what you are trying to do at the moment is likely only to end in tears :)

I'm guessing that your amplifier doesn't have the necessary output to run a powered sub from which is why it was supplied with passive subwoofer.

If that's the case there is nothing that you can do about it apart from replace it with a system that does allow an active sub to be connected to it.

i'd be worried about the sub as well. it could very well be damaged.
