  • Great for money and reliable
Model: GP-1000.2
This little beast was able to push 2 12inch 2ohm speakers wired to 4ohm no problem. Although, it was maxed out on the bass boost and gain, it still sounded great and never got to hot and played for hours at a time. Highly recommend if on a budget and cannot afford the high end amps or if you don't care about high end and just need a reliable amp, this is your guy. One thing I did not like was it did not have a set of output rca so you could piggie back another amp to it . Other than that it is now collecting dust due to upgrading the 2 12s to 2 15s skar ... show more

  • Read my review before buying if you are unsure
Model: GP-3500.1D
Awhile back i had a 1000 crunch amp and i loved it for my budget system and its reliability. It prolly put out maybe around 400 watts and did the job for me These are great for budget systems or smaller systems crunch just like many others do not put out their rated watts ! If you want true wattage go for name brand like skar kicker and others These are great but do not expect true wattage keep in mind i have this hooked up to a 1250 rms skar sub and it powers it well not to where it will damage it at all This works great for my budget set up glad they are an option but my other vehicles system that is bigger is skar amp and sub ... show more

  • WASTE OF MONEY
Model: GP-1500.4
Purchased in December for a Christmas gift for my daughter we didn’t install it until after the holidays beginning of January 2025 worked great for about a month then all of a sudden went into protection mode and stopped working by February don’t waste your money invest in something better.

  • Not as powerful as expected but great amp for the price
Model: GP-1000.2
The media could not be loaded. The amp is very solid. It creates a small hiss or hum when on but as soon as you input music you don’t notice it. It has both low and high inputs. The watts only test out to be 22w x 2 not 100w x 2 that I was hoping for. Good quality sound at high levels though!

  • Nope
Model: GP-2500.1
2500 watts in some dream land. Maybe 350-500. Maybe. Gets hot quick and goes into protection mode and shuts down often. Sound quality is basic at best. Spend the extra money and get a better amp. I cannot recommend. I’ve given it a chance and it’s too late to return it.

  • lie about the power ratings. Check them I'm not lying I'm disgusted for buying.
Model: GP-3500.1D
I bought a 3500 watt class d one channel crunch amplifier and it was supposed to be one of the best they have. I know RMS watch drop down to around 800 on an amp that big maybe even 600 that's fine. I am so upset with this amplifier... I took it to a audio shop and had the pequots and the RMS Watts tested and the peak was only ran to $642 Watts. And RMS didn't reach over 250.. It's supposed to be $3,500 w class d. With a full bridge I should be getting the whole 3,500 to one speaker. Will it hooked at one channel I should be getting 1750 Watts. I don't understand I did not get 115th of what I paid for. I don't care if the damn thing lights up I'm not looking at it when I'm driving anyway it's in the trunk. I guess it's in the trunk cuz it's jump. If I get a new one it's standing inside the car. It will not be crunch either. I did some investigation on some other peak power and RMS pools on amplifiers and stinger is killing it. Why don't you follow a little of their diagram and you might get somewhere.. by the way I did own both of the amps. I got rid of the 2000 watt class d because I wanted a bigger one and I really think the 2000 watt harder than the 3500. It is kind of crazy I wish I would have did a test on the 2000 w before I sold it. I will never buy this brand again.And I encourage anyone else not to buy from crunch. ... show more
