Beast of an amp

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

This amp is a powerhouse. Just make sure you have the power to run it. I added a 250 amp alternator, big 3 wiring upgrade, and added x2 extra batteries and I still get voltage drop when the bass hits. Although it's above 12 v ( drops from 14.4 to 14 down to 13.3, sometimes lower, depending on the track. Super sleek design, the bass knob looks sleek as well. Excellent Korean amplifier. This amp caps off and showcases my all nvx build beautifully.

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.
