### ⭐⭐⭐⭐⭐ One of the best...
*by J***O on June 13, 2024*

So far this is one of the best amplifiers I've used in recent years. I was a professional installer back in Circuit City days, and have installed many different amplifiers over the years. I have gotten back into it in recent years and have had the chance to play with some of the more well know brands (Kicker, JL, JBL, Pioneer, Skar...) and this little amp will hang with them all day if paired with a good speaker. I have it setup in my wife's Jeep running a single Skar VD-8 D4 in a custom enclosure. It took a couple of weeks to break in the sub but now that that is done, the combo is amazing! At Jeep meetups, I've had people ask me what I'm running only to be confused that it's a single 8 inch sub. I have the amp mounted discretely under the front seat and the gain set at ~ 50%. The source is a Stinger HEIGH10 head unit with 5V pre-outs. For the cost of this amp, I will be buying more of these for future projects! Highly recommended!
