Probably not the best amplifier for "high end" systems, but absolutely the best performance, and sound quality for the money! I am using 2 of these so far in a 2019 wrangler JLU and the sound quality is excellent (measured while standing still). I am using one of these to drive 2 6.5 subs (custom boxes) dual voice coil in parallel, amp in bridged mode (2 channel). Roughly 250 watts per voice coil, and WOW the bass hit is fantastic compared to the stock Alpine sub. All of this is with one of the lowest thd ratings, and highest signal to noise ratio. I can attest to the signal to noise ratio being real at 107db. Volume low provides very little audible noise
For the price, this amp has the most power, cleanest THD, and best signal-to-noise ratio. This will be my 3rd one, with the oldest being about 4 years old and still going. These are class 'D,' which are very efficient, easy on the electrical system, and don't get too hot. Ideal for tucking in tight spaces.
