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: Perfect for my bike! - Absolutely perfect for a small setup like a motorcycle. I have this running two 8", 2-way SKAR Audio Marine speakers in 8" Audiopipe cans. No complaints what so ever. Very compact. Fit in the compartment under the rear plastic where my tool bag used to be. 5 stars all the way. 💯👍
