Review
I am an audiophile, one that appreciates quality sounds. But there is one problem, I do not have much funding to do up a high-class, blasting in-car stereo system. I do have knowledge and experience in installing stereo equipments, and I figured out that by using this BitTen processor, I would be able to dish out quality sounding audio even by using my OEM sound system. After a few hours spent installing this processor into my ride, I was ready for results. Powered up my sound system, turned up the volume; my, was I amazed by the sound quality enhancement by the RS-P99. It even surpassed what I was expecting! Better sounding tones, along with crystal clear, undistorted delivery. This was definitely a great device to get once you get someone knowledgable to get it done for you.

What I like
The major enhancement in quality of the audio system. Even when using OEM stock sound system.

What I do not like
Slightly costly, and requires much knowledge on installing processors.
