I have a extra 4 channel amp Is it a bad idea to put it to my stock Mazda 3 speakers?
I second this. It will sound a lot better just make sure you dont overpower them. Amps always sound better than headunitsYou'll notice a good deal of improvement as long as the factory speakers are in good shape. And keep in mind that factory speakers are only rated for about 15 watts, so driving them with a lot of power may damage them.
The size of the motor doesn't dictate power handling, especially if the factory speakers have neodymium magnets. Have you ever safely added an amplifier to factory speakers? Lots of people have done it. If the OP blows his speakers it's a lesson learned, because it would happen from carelessness.look at the motors on your stock speakers and then think about if you want to amp them.
I say you do it, then when they blow up you will be forced to spend some money on something other than making your trunk rattle to death.
