This amp is a beast

The following review is for XCA3K, which is a part of the bundle you are viewing.

Highly underrated (so be careful), great looking, great sounding amplifier for your 3k ... or even 5 k needs (check the dyno video). I'm thoroughly impressed by it especially with the clarity and power. NVX has been my GO TO brand since I came across them and this amp is no disappointment regardless of what you put it up against.
