The Do Nots of Setting up a Sound SystemThe electrical wiring will have to be set up very carefully so do not connect wires in random slots until they are correct. This can lead to short circuiting and essentially broken speakers.
Do not work with plugs in and electric on. Some sound systems can be pretty volatile and so its best to leave the electrics disconnected until a time at which the sound system is completely setup.
Do not assume you do not need the manual. I know you may be a man but the manual was written by someone a lot more knowledgeable on sound systems so I highly recommend reading it.
The Dos of Setting up a Sound SystemDo read all instructions very carefully. This will lead to your sound system being set up correctly and in working order.
Do ask for advice from the store that you buy the sound system from as the salesman will know his product inside out and be able to give you save great tips on what to do and not to do (maybe even some things that I missed!)
Sound Systems can be expensive and wiring can sometimes be tricky and sometimes you need the electrics on to make sure it works. In cases like this I highly recommend wearing rubber gloves as the volts and amps going through that sound system could be a potentially dangerous amount.
