Review: Perfect! (don't forget to add turn-on lead!) - Fantastic little compact amp, for cabin of my sailboat. Very efficient, and just the right amount of sound power for my little Garmin Fusion stereo. Two front channels for 6" speakers and two rear for single 8" sub. Note, I at first thought it was dead, but then realized I need to add 12v to the middle power terminal (turn-on lead). Duh.
Review: Definitely compact - Brought these in Feb 2024 to build my system on my Harley and as u can see they both definitely fit inside the front fairing comfortably absolutely perfect nothing needed to be modified to fit and the front fairing went on without a problem. They definitely pack a punch as I have 1 amp running the front 4 speaker and the other running the rear 4 inside my saddle bags the clarity is astonishing they are paired with 4 ds18 pro 6.5s and 4 ds18 pro 6x9s absolutely love them

### ⭐ Stopped working after only a few months
*by D***L on August 21, 2023*

I purchased the Compact Amplifier with high hopes it was the only one small enough to fit in my motorcycle. For the first couple of months, the device worked like a charm, delivering clear sound and amping up my radio's performance. I was genuinely impressed by its compact design and the noticeable improvement it brought to my listening sessions. However, my enthusiasm quickly waned as the amplifier unexpectedly stopped working altogether. It's disheartening to invest in a product that initially demonstrates so much potential, only to face such an abrupt breakdown. I tried troubleshooting, checking connections, and testing different setups, but unfortunately, nothing revived the amplifier. While the initial experience was promising, the amplifier's sudden failure has left me feeling disappointed and frustrated. It's disappointing to see a product with so much potential fall short in the longevity department. I had hoped for a reliable audio enhancement solution, but unfortunately, this product didn't meet those expectations. In the end, I find it difficult to recommend this product given my own experience. The potential it showed initially was overshadowed by its short-lived performance. If you're considering purchasing this amplifier, I would advise proceeding with caution and being prepared for the possibility of encountering similar issues down the line.
