Perfect size and output for my needs

My wife bought me this amp for my birthday. At first I didn't care for the speaker output pigtail (would prefer screw terminals), but during installation it helped to keep everything nice and tidy on my board. Seems to deliver plenty of clean power to my components and gets plenty loud for what I want. I love the small footprint!

Good customer service

I only can complain about the inputs. I wish the inputs weren't pre assembled on the clip so I could use my own wiring

Great Little Amp

I bought 2 of these during the sale event and installed one in my daily F-150 Super Crew, and just finished the second one today in my daughters Mustang. There are rumors of heating issues but haven't experienced any yet. These little amp sound great. I'm very impressed with their small size and great sound quality as well as the level. I definitely recommend this amp especially when a small size is needed.
