Harmony Audio HA-A1500.1 Car Stereo Class D Amp Mono 3000 Watt Subwoofer Amplifier - 1 Ohm Stable - Includes Bass Remote

I'm impressed! This amp pumps out true rims and I would highly recommend. I'm about to order the 1500. Thanks

Great amp power is fantastic. No complaints . Works as advertised . You won't be disappointed. Shipping was perfect .

I am using this to drive a subwoofer in my Travel Trailer. I have tried it into 2 ohms, 4 ohms, 8 ohms and also into an oddball that burned up its amplifier that measures 29 ohms. That amp just powers through. I have to put the gain way down or it would make the 15 inch sub destroy my trailer. Only about 10 hours on it so no real look at long term yet. So far I am not really stressing it at all so I think it will last as long as I do. It could be improved with some additional markings on the settings dials to at least indicate approximately where various frequencies are. You have to think in logrythmic to make guesses. I will have to dial in settings once I have the whole HT done.

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.

Works great and doesn't get hot. It will push my 10inc sub pretty good
