Sanyo M9990 speaker wires scheme

hardmen · Jul 14, 2015

Hello all.

Bought a 9990 from Adam without speakers.
The spares JVC M70 speakers fits perfectly, but I don't know how to wiring the cut wires for testing.

Here the pics of cutted wires.

Thanks Goodman.

Do you know, if tweeters using capacitors (as 1st order crossovers) or if that mini pc board ARE the crossovers?

Cheers.

The mini pcb is the headphone jack board. It appears that the tweeter high pass caps are located on that board (C850/950).

With new tweeters and woofers (M70 Woofers).

Make the wire scheme that show in pictures above!

But unfortunately,the only thing working for now, it's the Dial LEDs.
Any idea?

Cheers.
