I just want a bit more punch and quality sound..I never had to modify the sound system on any car before but this one is really lacking on every aspect. Not sure if this will be achievable with just replacing the speakers.It depends on how you want your system to sound. You can get your stereo to sound really good just by adding power, adding sub(s) and upgrading all of your speakers. Doing these things can drastically improve the sound but it depends on your preference.. take a factory speakers.. compare it to a a quality aftermarket speaker you can tell just by holding the 2 in your hands how cheap the factory speakers are.. that’s one reason the sound quality is lacking.. add some juice and some punch and you will not believe It’s the same system your listening to!
I would be happy with just replacing the speakers and adding an amp if needed but without a sub.
