@@ryanamen6397 in my own opinion , by listening to it hooked up to a H.Q. source & speaker system while comparing it to known H.Q. amps using ones own experience. So other than using a dyno, its always just an opinion. Can anyone else add to this?

yeap... hole saw... but FIRST you need to KNOW what part gets hotter: toroid or the sides? no point in cooling the luke-warm parts and for this you need to run it full bore, in the heat of a summer day, 40ºC minimum in the car/trunk, and its also good to have hi pwr resistors, or hi pwr 12 or 15 inchesrs

Well... technically, it performed as advertised, and then some! A lot of their compatriots didn't even make the low bar of advertised power. I agree that longevity is still a question mark. But, it's pretty clear there was an engineer that knew what they were doing involved at some point. It would be fairly easy for a handy soldering hand to repair this, or sub out known brand name parts if one wanted to. Also, I would love for that clear acrylic cover to be the standard.

With the model being ZM2502, Makes me think it translates to 250w x 2 channels. It certainly didn't do terrible in testing. The 40a x2 fuses made me think it should do something more in that ballpark.
I was wondering about why they used 2 x 40 amp fuses with that 300 watt rating. With those fuses you would be able to hit over 1000 watts at 14 volts. SQ is always a factor too, it's what I aim for.
@jamesplotkin4674 Exactly. Back in the day I paid out the nose for a Kicker ZX amp, and also JL Audio's 1st-gen class-D 500-watt monoblock. But the reliability and sound quality was superb. I could be wrong, but I wouldn't bank on any quality coming from Temu.
10:57 You want to get into electrical engineering and dissect an amp for $100 that's a perfect specimen especially if you push it to its limits have it fail and then repair it. Even cheap amps have their purpose. ☺️👌
Guessing approximately 800 rms Bridged....😊... I usually take total fuse rating times 10 volts because of the loss of efficiency.... gets close usually.... it did better than expected
Like I always say, the car audio world is a huge mess of brands and non-brands and you never know what you may get. There are alot of fake brands that don't do much power at all and then we have fake brands that actually do for a great price. It's a risky business.
It is risky especially when you cant see what's inside till you get it Stateside. The thing about it is.......This "cheap" stuff is getting pretty damn good in the last 4yrs. Maybe the restoration of electronic components (after Covid) plays a factor in the grand scheme of it all. Time will tell.

Very few US owned car audio manufacturers anymore. Those three are usually offer proprietary designs along with service and warranty support. You'll get nothing with this amp.
