So do I, but basically he has removed the DSP, found the 4 speaker output wires from Bm54 Radio tuner and connected them to a new smaller amplifier and then reconnected the speaker cables outgoing to the speakers.
I'm pretty sure you could get the sound system back by simply removing the DSP, finding the 4 speaker output wires from the BM54 radio tuner and connecting them, in the correct order, to the output speaker cables.
The DSP isn't an amp, the radio tuner contains the amp.
Really depends on how far you want to go.

Any option just to get some music would be great. I do appreciate your help, Thanks Brian.

So if i remove all three plugs from amp. The two smaller ones i take are speaker in and speaker out.

We have music yes music Thanks niceday your help was invaluable. A wiring diagram would be a great help to sort out all the speaker wires.

There you go, another miracle,
All you need to now is tidy things up and account for all the pairs of speaker wires.
If you pm me your email address i will send you the wiring diagrams.
I would post them on here but they don't copy very well.

My sincere thanks go to nicedayforit for all your help its now working ( well 6 speakers are )

Good to hear it all worked out Brian.
You have of course set a precedent as to how to get round the problem of a u/s DSP unit.
