Light turns on but no sound


This is a powered sub, which means it has it's own amplifier providing the power for big bass. When you removed the back you probably removed it's amplifier too so it's normal that now you only get the bass performance of a normal speaker.

Aiwa tw60 subwoofer have power but no woof sound


Aiwa isn´t a good subwoofer. The best are Rel, Sonus Faber, etc.
Here is the characteristics:

.1 20 watts, Min. RMS at 4 ohms, from 40 Hz to 160 Hz, with no more than 1% Total Harmonic Distortion


The subfrequencies are below 25 Hz, but TS-W60 work over 40 Hz!.

Bass frequencies (woof) are from 25 to 50 Hz.

Bad, very bad.

Sell it and buy a good subwoofer.

My Aiwa powererd sub-woofer TS-W50U) has crackling sound.


Crackling is an unusual noise but typically indicates a bad capacitor in the amplifier board. This can be a rather costly repair but first we will go through basic trouble shooting steps.

Reduce the volume on the sub and see if the noise remains and changes with the volume.

Unplug the sub and disconnect interconnect cables. With both hands push softly on the speaker cone to move it in, let it back out and do this a few times. If you hear a scraping noise and some resistance your driver is misaligned and you need to recone or replace the driver.

Check all your interconnect cables, there may be a bad internal connection (usually causes pops and cut-outs).

Let me know how things workout. If it makes the crackling noise at all volumes and the driver seems fine then I would seek a professional to repair it, or replace.

Cheers,

Kevin

Sounds like your original and this sub have bad amps. The amp for the sub is not the same as the amp for the other speakers. The old unit has a dead amp and this new one is on the way out. (Pulling too much current on high bass)

Speaker/sub bass


Hi, it is possible that the sub volume control is worn out. If your particular brand/model uses the rotary/wiper type (variable resistor) then replacing it should do the trick but this involves soldering which be done by an electronics technician or qualified to perform such repairs/replacement. Hope this helps. Cheers.

Volume knob


Normal Aiwa compact shelf units use what is called a jog switch for the volume. Usually you can tell the difference if when you you turn the volume up or down. It goes a short distance and seems to spring back. In this case there are two momentary contact switches. One for up one for down. With a plastic lever on the back of the knob that bumps the approriate switch whether turning down or up. If the lever is broken it will bump up against one but not the other. If it is broken plastic you know how good gluing plastic goes it never seems to hold.
