“Can I hook up additional LG speakers to this system? I have another sub and same type of speakers as this one. If I have 4 speakers and 2 subs wired in will it burn out the amp?”

The LG XBOOM 700W 2.1ch Mini Shelf System with Subwoofer and Bluetooth®, Model # CM4590 does not have additional ports for adding more speakers or another Subwoofer to it. The output amp is designed to output to the speakers that come with the unit. Both the Front Speakers and Subwoofer have an impedance of 3Ω so the total impedance that the amplifier sees is 12Ω. Adding two more speakers and a Subwoofer of the same impedance would up that total to 24Ω which is more than the amplifier is designed for. If the amplifier is overloaded, it will either turn itself off or reduce the power to protect itself. Speaker impedance changes amplifier power output. In fact, your amplifier power could be nearly half or double its capacity – depending on the impedance of your speakers. While speaker impedance changes amplifier power output, it is not a major consideration for most users. It only becomes relevant when running your amplifier at full power, and then it is best not to run it too close to its design limits. Speakers can be connected in series or in parallel. The maximum power output of an amplifier is dependent on the amplifier design and total load impedance of the speakers connected to it. In summary, halving the total impedance (by doubling the number of speakers in parallel) can increase the power output of an amplifier. In theory halving the load impedance will double the power output of an amplifier. In practice this is rarely achievable. Even if the power output is doubled, that would only increase the perceived volume by about 25%...^IFV
