This means that even brand new vehicles and lease vehicles can be upgraded and returned to factory condition relatively easily if and when wish to hand the car back.
Even the premium sound systems need the PL-Autotek Touch
The two-way APBMW K4E kit creates a three-dimensional sound stage and give the musical message the essential timbre accuracy. The 100 mm (4 in.) midrange is provided with a water-repellent pressed-paper cone, a material providing natural sound. It features a low resonance frequency that allows hi-pass cut-off in the 150-200 Hz range for an excellent mid-low reproduction. The 25 mm coil and Tetolon dome tweeter features a great extension on both medium and high frequencies and is optimized for off-axis output, for an extended sound stage in the three dimensions, that amplifies the perception of reality in the car cabin.
The 200 mm (8 in.) APBMW S subwoofers allow a direct replacement of the OEM speakers underneath the front seats, making the most of the factory acoustic load and generating deep and crisp low frequencies. The Neodymium magnet allows for greater power and control than ferrite while maintaining the depth of installation unaltered.
Modifications are to the factory enclosure to extend frequency response beyond its original design. This results in a smoother and fuller sound.
Great sound cannot be achieved unless you remove unwanted rattles and external noise. Then, you enhance the sound by creating a stable platform for the sound waves to propagate correctly.
The most critical aspect of setting up an advanced high-end audio system is understanding the capabilities of each speaker and adjusting the settings to ensure optimal sound quality. This process starts with pre-equalization, correct crossover points set, and time alignment measurements are set before listening to system in its most basic state. Typically, reference microphones and multiple digital-time analyser's are used to monitor the sound and ensure it matches the desired signal curve. Further and human adjustments are made as necessary. With well over 30 years of professional audio, you can rest assured it is going sound amazing.

I recommend leaving these stock, as changing them would have minimal impact on overall sound performance.
