That thing could barely take 300 watts RMS despite the rating. When it finally went out, I bought this micro amp after I saw a guy on YouTube power 4 kicker solo baric subs with it. I was like “no way this tiny thing will perform like that!” Boy was I wrong! This little guy packs one hell of a punch, especially for 60 bucks! Not to mention the sound quality is so much better than that Walmart amp I bought. I have it hooked up to two Planet Audio AC10D’s in my Mustang and I couldn’t be more impressed!
