ZG-1200.2 Zeus Gamma ZG Series 1,200-Watt Max 2-Channel Class A/B Amp

Awesome amp. Powered right on and delivered good clean power to my subs. I've had several of these Hifonics amps, they have all done well Buying another one today. Thanks!!

I have this app wired in parallel to dual voice coil ( 10” sound town ) in a prefab heavy vented box and it hits really hard and with the head unit I cam tune the frequency and gain. I LOVE THIS AMP… had it 3 years so far and don’t skip a beat… lol pardon the pun. I also have a Theta 1425. On custom speaker arrays. Just as clean but swapped this out for my old JL 4 channel 2800 watt and it blows the theta away. All in a 2007 crue cab Colorado. The tweeters are horn tweeters that are so loud and clear is amazing. The hi- phonics and is amazing…This stuff is going in my next vehicle period. I think I need a 3 or 4 Farad cap to stop the pulsing lights lol

This amp replaced my Skar RP4500 class D monoblock when it died. I'm powering it with a pair of 1,000 CCA lead acid barreries and a 1 0 gauge copper wiring kit from Skar. It sounds great and i'm not looking to change it fe another amp...ever! This is my 3rd Hyfonics Class D amp and Ive not had bad experiences with them at all.

Awesome amp so far just have it pushing 2 6.5 hifonics components in the doors and 1 10 rockford fosgate prime 2 ohm and im waiting on my jbl's right now. But i can definitely say that hifonics is the shiznit ive always liked receiving my power from the gods. Excellent **(*UPDATE** 5/29/23 A little over 2 years and this amp is still pounding done blew a couple component 6.5 Hifonics speakers and now I'm gonna be installing a new pair of Infinity REF-6530X in my doors. Can't wait to see how they sound with this Zeus pushing them. One tip I could maybe give is to make sure you have a good clean size wire feeding it, (min. 4awg) I've got a 2 gauge running it with a amp input reducer and it's been fine. And my gain is only turned up to about half way. ****another update 8/28/24**** This one hell of a amp. It's still working flawlessly and I have yet to have this amp go in protection mode. It does get a little warm but I helped that by mounting it on 3/4" spacers to help with air being able to flow under it too. That seemed to help because now I can touch it and hold my hand there where before it was almost too hot to touch. And no I don't bump this amp every single day but damn near close. I'm a believer in installing overkill wire gauge sizes. I think that helps all amplifiers. If it calls for 8 gauge I install 4 gauge. But then again I've never installed any amplifier with anything smaller than 4 gauge. I actually have 2 gauge for the ground on this amp. Couldn't tell you if it helps but I do know it doesn't hurt

It's a very good amp if you're running highs or mids it's not good for Lowe's above 10-in woofers anything bigger than a 10-in woofer overheats the amp so I cannot honestly say it's a bad amp I tried to push two Kicker Comp vrs 12-in woofers and the amp just couldn't handle it it wasn't made to push that big and that hard of speakers so if you're looking for a Hifonics amp that can handle your 12-in woofers get the 1200 1D Zeus gamma it is a very good amp I plan on buying that amp very soon

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.

I bought this in November 2025. Unfortunately I didn't open until now and this amp is not working at all. Return date was January of this year . So I’m upset that I didn’t have the time to check out. Goes to show don’t be trusted worthy, check it out when it comes in.

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.

Works nicely but goes into safe mode from some bass

The item powers up but no sound. Fauly item

Abri mi paquete y vi que los sellos del amplificador están rotos además las conexiones de plastico de las bocinas se ven como si ya las hubieran usado. Voy a comprar los cables para prenderlk para ver si esta funcionando bien sino lo devolvere. Dejo fotos de lo que estoy comentando

Wasn’t expecting much for the price but this does the trick nicely. Good quality. Great price. A+

Solo debo decir que se escucha muy bien, tiene una potencia decente para los que les gusta la calidad en vez del sonido exorbitante, físicamente es muy bonito su terminación de aluminio y sobre todo de noche con su iluminación LED, sin duda te llama la atención.
