Best Car audio

The best car audio would be SONY and Pioneer, the other are more costlier.

Go for the USB model of SONY and JBL speakers. This would blast your car when played. I own this combination and it really rocks when you play.

Pioneer is also good but for more audio lovers SONY and JBL will go because,

SONY and JBL
SONY players will give the clear and distortion free sound signal.
JBL speakers can deliver the distortion free sound output.

So this works well and have worked well.

Pioneer
Pioneer has that punch and most of the car lovers go for pioneer for its power on the subs.

Bottom line : Speakers power should be greater than the player output power.
