A:AnswerThe LG XBOOM 300W Hi-Fi Shelf System, Model # CK43 only features an FM Tuner, (FM Tuning Range 87.5 - 108.0 MHz). IT does not have an AM tuner...^IFV
A:AnswerIt comes with two speakers, that are attached with separate R/L +/- speakers wires. You can add more speakers the same way I'm sure, but be aware that the speakers are matched to the system. I'm not sure how many ohms the system speakers run on, and that's critically important to the efficiency and volume of sound. Remember 300 Watt RMS doesn't necessarily mean it can drive large speakers, chances are you need very efficient speakers with a low ohm rating to work well with this system. It's doable, but you'll have to do some homework to make it sound good.
A:AnswerChances are, no... It really depends on your turntable. Unlike most discreet audio components turntables require a preamp to boost the signal before it can be amplified. Some new turntables don't need this, so your best bet would be to check your owner's manual from the turntable and verify that it can run without a preamp.
A:AnswerNo, unfortunately not. This isn't unique to this LG system, many manufacturer's have omitted AM from their receivers. I get around this by using my iPhone to stream AM stations through the Bluetooth connection however.
