keeping the factory amp gives more complication, so most people just bypass them

do you know how to bypass it?

In fact if you're keeping the stock speakers, and it's not a Bose system, it's easier just to keep the amplifer. However, if you want to bypass, just identify the input wires from the head unit, identify the output wires to the speakers, pull the plugs, and solder in jumper wires to connect each input to each output.
