Hifonics ZG-1800.1D Zeus Gamma ZG Series Amp (Monoblock, 1,800 Watts Max, Class D)

Works nicely but goes into safe mode from some bass

It's keep on chipping out even wen I turned down the Bass am disappointed 😞

Muy buen amplificador suena increíble lo conecte a 2 subwofer de 12 pulgadas jl audio y cumple de manera brillante

I installed this amp on 2 Skar Audio 8" Subwoofers with 1400W total and 700W RMS. Because this amp is 1 Ohm and my setup is 1 Ohm I only need to turn this up about 1/3 for the gain. I most always buy a bigger amp then needed so I can keep it going for longer periods of time. If you don't have your amp tuned by a professional just make sure that when using the low level inputs from a line out converter or aftermarket head unit, that you set the outputs to 5VAC. This keeps the amp happy and is the most it can take from an input. Anything higher will cause the amp to get unnecessarily hot and you'll just have wasted energy and the amp will likely go into protect mode. I also have this amp cooled with a fan. When using a fan to cool your amp you need to make sure that the amp is elevated by using some nylon spacers. This ensure the airflow actually passes around the amp and not just hitting the side, which will cause the fan to be useless for the most part. You'll need to install a relay and fuse for the fan as well or you will burn up the fan within a month or two. One other thing to note is the set screws from the 4AWG power and ground... They broke when tightening them so you'll need to get some heavier duty ones from your local hardware store.

As to the product company first: hifonics, hands down, one of the best by far. This amp puts out power non stop. Gets hot and don’t quit. It is also very smart. If your set up is a little off adjustment like on the boost level, the bass knob will light up red and no more sound will emit, but a minor adjustment to it, restart your car, and your back in business. This feature is there to not allow an overload and protect both your amplifier and speakers which you work so hard to pay for and own. On the negative side is only for the company in which I purchased from. It has in the past been a very good company to get my equipment from, but I recently had to return something and even though it was undamaged and unopened, they charged me a huge restocking fee. :( even though it said no hassle returns on the ad, maybe it has something to do with this messed up virus crap idaknow, not a deal breaker to order from them again, but I will make sure that any purchase I make from them in the future that I am “all in” from the git. Otherwise, I recommend this product any day.
