If you're looking for a great sound system in your Prius, then you should definitely consider the JBL sound system. There are two different types of JBL systems available for the Prius - the Performance Series and the Reference Series. Both of these systems offer excellent sound quality, but there are some key differences between them that you'll want to consider before making your final decision.
The main difference between the two types of JBL systems is that the Performance Series is designed specifically for use with Toyota's Entune infotainment system. This means that if you have an Entune-equipped Prius, then choosing the Performance Series will give you access to features like Bluetooth streaming audio and hands-free calling. The Reference Series, on the other hand, is not compatible with Entune and does not offer these same features.
Another key difference between the two JBL systems is that the Performance Series offers a bit more power than the Reference Series. If you're looking for thumping bass and powerful sound, then go with the Performance Series. However, if you're just looking for great sounding music without all of the bells and whistles, then go with the Reference Series. It really comes down to what your personal preferences are when it comes to choosing between these two great options from JBL.
