Kemo M032S 12 Watt Universal Mono Plug and Play Amplifier Module with RCA Input
Bridge Audio channels
What could I use to bridge the audio input channels into one input for this amp? I would like to have a full output mono speaker.
In my first reply I should have mentioned that, although the splitter will work in many cases, it would be best to put a resister in series with the center conductor of each output channel before connecting them together to the mono input. Approximately 470 to 1K Ohms should work.There is more info on the best way to do this at www.prosoundweb.com. There is a article called "Why Not Wye" it contains a good discussion on the subject. Or just do a web search for why not wye and you will get even more info.

can i use this amp for a passive 8" home theater 80 watts peak, i would like to turn it from passive subwoofer into power subwoofer,
my home theater receiver doesn't support passive subwoofers only power subwoofer, i already have the subwoofer i don't want to spend much money for now.thanks,,,,,
Technically yes but with a maximum output of 12 watts you will not get much out of the subwoofer and the amplifier will likely clip very easily which could damage the driver over time. I would recommend the SA25 instead.

Can I use the Kemo M032S to amplify a mono phono signal without using a pre-amp?
Will I need a pre-amp module such as Kemo 040N to use this with an old portable phonograph?
It really depends on the cartridge of your phonograph. If is Ceramic you should be good to go. However if you have a MM or MC (Moving Magnet or Moving Coil) cartridge, the record player will be outputting less than 80mV (minimum requirement for this amp) and you will need a phono preamp.Be aware that not all preamps are the same. Phono preamps not only boost your turntable's output, but also apply the RIAA Equalization(1). If you are going to listen to records 1955 and later, I would not skip the equalization. I have suggested some preamps with the RIAA equalization below.(1)RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA). The purposes of the equalization are to permit greater recording times, improve sound quality, and to reduce the groove damage that would otherwise arise during playback.A recording is made with the low frequencies reduced and the high frequencies boosted, and on playback the opposite occurs. The net result is a flat frequency response, but with attenuation of high frequency noise such as hiss and clicks that arise from the recording medium. Reducing the low frequencies while recording also limits the excursions the cutter needs to make when cutting a groove. Groove width is thus reduced, allowing more grooves to fit into a given surface area, permitting longer playing times. This also reduces physical stresses on the stylus which might otherwise cause distortion or groove damage during playback.
