No complaints . Works as advertised . You won't be disappointed. Shipping was perfect . Review: Harmony Audio is no joke - I'm 50yrs old . Been a bass head my entire life. Owner of many spl builds. If its been made I've usually ran it. With that being said. This is one of the most impressive amps I've ever owned . Bang for buck is an understatement. This amp produces WAY more power than it states. No heating issues of any kind. I was so impressed . I bought 5 -1500.1s ,4-800.1 , and 1-400.4 Make sure you have proper electrical . Upgrade your alternator, throw in a scib or cmax bank. Don't run a Walmart lead acid battery and expect miracles to happen. Most folks that bash an amp that is PROVEN normally have no idea how to wire one up properly. Don't use fishing line for power and grounds. Make sure you run some 1/0 OFC Minimum!! Buy you some reducers and install the amp on an amp rack not the back of the subwoofer box. SMH! For the people that install the amp on a box. How about put your forehead against it and turn the volume WAY up . You will probably then understand why NOT to mount the amp to the box. Lol Amps run cool, very efficient. I've had absolutely no issues of any kind. Over the years I've learned that most manufacturers have to start from some where in order to get recognized. I truly believe this amp line will be a amp line to contend with in the future. I also have the monolith (2) 12s running 0.5 ohm on a taramps smart 3k . That's 7855 watts going to 2 subs. They have no issues whatsoever. Im also building a demo vehicle with (3) 18s monolith series. These monolith speakers are built high quality as well. I have (2) Md12000.1 0.5 ohm versions for demos running 2 12ks on 3 harmony 18s .These subs are built like tanks and DO NOT get hot. You can't go wrong with the monolith series subs or any of the harmony audio amps. Small but extremely powerful . I just wished they made an even more powerful monoblock. These 1500s were put in the category of a 3k budget amp test. The results came back harmony #1 . Also their 18 monolith subs came back #1 . Do your research. Look at Williston Audio most impressive amp dyno video. Harmony was #1. Darren has tested 100s of amps ..The dyno doesn't lie. ## Features - 3000 WATT PEAK POWER: With a peak power output of 3000 watts, this amplifier delivers robust and dynamic bass, ensuring a powerful and immersive listening experience in your vehicle. - 1 OHM STABLE: The amplifier is 1-ohm stable, allowing for flexible subwoofer wiring configurations. This feature provides versatility in connecting multiple subwoofers and optimizing impedance for maximum power output. - SMART POWER CONTROL: Solve the challenge of finding a switched 12-volt wire with Harmony Alloy Amplifiers.
