Hi, im currently looking to upgrade my car by making a few changes.
The volume control isnt really that loud, and i want it to sound like a concert in my car.
1) Can i just change speakers to help with this problems?
- if yes, what size and what kind of speakers do u recommend?
2)Or would i need an audio kit?
Please Help!!!

louder would require doubling the power or doubling the speakers. However since the factory speakers are cheap, i would replace them and amplify them.

6.5" component up front, 6.5' rear speakers, 3" center and a 10" sub
