Loud and clean

The following review is for Kappa 63XF, which is a part of the bundle you are viewing.

For $99 you can’t go wrong, I have these running on an Alpine 4x100 rms amp and they sound clean with impressive bass, I’ll probably get another pair for the rear doors now.

Nice Clear Sound

Highs are much clearer and bass is much more present and defined than with the OE speakers.
