Do speakers with larger magnets have more power & sound quality than ones with smaller magnets?
Respect and love and peace to you my friend. I think larger magnets must produce more power because the lines of magnetic flux produced will be stronger with the interaction of the turns of wire and current flow through them. They should give more or better quality bass but the amplifier will need to push more current, so you must check that the amp is powerful enough to ‘drive’ the speakers or you could blow the amp up! This is called – impedance matching where I come from. I don’t know anything about Cadillacs – sorry. Hope that makes some sense. Good luck.
