Today i put some new door speakers in my car. They are some 5.25 inch 2 way (maybe 3 way, doesn't say on the box) speakers i found for cheap on amazon from JVC. I installed them and was using VAR 03 and was very pleased. They sounded great, but there seemed to be too much vibration for the speakers for higher bass notes, lower ones were fine, but mid bass was a bit much. I put VAR 02 on the stereo and oh man it's great. My door speakers are even more noticeable than before and the it helped a lot with the midbass problem. The highs sound great and low bass doesn't get distorted at all.
Best receiver technology ever.
