Review: Perfect - This is What I was looking for my motorcycle, compact and powerful
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.

### ⭐⭐⭐⭐⭐ Definitely compact
*by G***L on 26 June 2024*

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
