High Tech Excellence

This amp is amazing and has dialed in my cars radio sound perfectly. I'm very impressed with it.

Pros: Small and great for hiding in tight spots out of view, easily adjustable, self tuning. Trouble shooting and adjustment videos are extremely easy to understand.

Cons: None. This is my first time using an amp like this and it's still too soon for me to give an honest critique.

Improved sound

Crutchfield customer from Lake Worth, FL on 4/28/2020

2020 Honda Civic

Very powerful amplifier, 50watts rms x4 high output delivers. Sound quality has changed with improvements in midrange clarity and bass output. I placed this into a 2020 honda civic hatchback sport, JL Audio C1 components on all doors, JL Audio TW1 powered subwoofer connected with high level inputs from the amp with bass knob. Everything melds perfectly. I cut out insulation under carpet where the glove compartment is and placed this there near the head unit.

Pros: Improved sound

Cons: Read directions. I had the input and output crossed at first. The amp went into protection mode. I read directions and found my mistake as I thought all inputs were on the side which included the power and ground. I rewired and worked perfectly without damage to the amp.
