Passive crossover scheme of Jamo S606, characteristics and frequence response of its speakers

SOURCE: bypassing the 150 watt blown amp with passive crossover

3/4 update: i bypassed the 300w amp on my first ovtr3 with a cs3006 crossover i purchased on ebay. the input wires at the base of the speaker were connected to the input of the crossover, the bass output of the new crossover was connected to the yellow/yellow-black lf+/lf- wires that used to leave the old 300w amp. the high freq output of the new crossover was directly connected to the leads coming from the speaker's tweeter (running the midfreq outputs from the new crossover to the input of the speaker's old crossover is no good, since the midfreq output of the new crossover would rolloff and provide little high freq to the tweeter). The mid-freq output from the crossover was connected to the input of the old crossover that came with the speaker (alternatively, i could have wired the mid freq output from the new crossover directly to the midrange speakers, but i figured the old crossover might have had some characteristics that would have been helpful. the result is better than i hoped for! true, the bass is not quite as floor shaking as before (and you need an amp that can boost +5-+10db below 350Hz and rolloff the boost above 350Hz), but the end result is more than satisfying and gives these speakers new life. I am using a Sony receiver that puts out around 200W for the front speakers.

If the subwoofer has its own power cord seperate from the rest of the audio system, the internal amplifier could be fried or u have a loose connection inside the box

SOURCE: passive radiator speaker wiring

Passive Radiators are not driven by the amp. They have no voice coil and no power goes to them. They are used to enhance the bass or lower frequencies in a speaker system. They work by utilizing the back pressure that a driver (woofer) produces. When a woofer produces sound, it moves forward and backwards inside the speaker cabinet. This backward motion is what drives the passive radiator. So in order for the passive radiator to work, it would have to be placed in speaker cabinet along with a woofer that is hooked up to an audio amp.

SOURCE: fried electronics in KLH ASW10-120B subwoofer

It is a 4 ohm nominal impedance woofer. If you put a new woofer in, it will last maybe half an hour and then fry/melt. The problem is the amp, not the woofer. Throw the amp out and use the box as a passive sub. Get a 100 hz sub crossover.

SOURCE: What stereo amp to be used with jamo s606 speakers (2.0)?

For PC music ( I suppose mainly mp3) you don't need any extra-quality amp, any older Yamaha stereo amp will do. I don't know which of them are available in stores near you, but if you write some model numbers I can check their specs and advise more.
If your PC has spdif output (coax or optical) go for amp which has digital input available.
