DS18 G1000.4D Car Amplifier GEN-X Full-Range Class D 4-Channel 1000 Watts Max Power 2/4 Ohm Stable, Bridgeable, High/Low Pass Filter - Small Compact Amp for Speakers in Car Audio System…

I'm starting out with just looks and craftsmanship, because I just received it and won't be installing until next week. So first Impressions it was well packaged with all the extra fuses and screws etc. Looks really well built very solid no rattling parts in a very tiny package fits pretty much in my hand . We will see how it performs when installed? Now with that being said , a lot of folks here on Amazon worry on The wattage and don't take into consideration other specs , lpts of watts doesn't do you any good if its not clean wattage. When I made my choice for this amp. The wattage was not the main consideration, my choice was made on these factors THD which is impressive @0.01% (A lot of other amps either don't listed or it's generally this # is very high) I was considering the Recoil 500.4 and it was @10%+ others do not even mention it) Another factor was efficiency at 4ohm which was very high 92%@14v, channel separation 55db , SN Ratio also very good @>90db. And finally 90w per channel @4ohm which if you multiple 25Amp for 2 channels x 14v which is more realistic for most vehicles = 350w ÷ 2 = 175 w then I always subtract around 20% because of voltage drop, rise in impedance etc. Would yield approximate 140w /ch @2ohm around 70w @4ohm those are realistic numbers. All these things made my decision easy and it gave #s I could tolerate as opposed to other amps. I will post updated after system is functioning. Good luck. Update 04/08/25 Changing my review to 5 stars. After installation this little amp sounds great, as I knew it would my mids and highs are crystal clear , no distortion whatsoever, it has good lows but not it's intended use I Have a 10" JL Audio sub that handles everything from 80hz down. It's powering 6 speakers and it sounds great. Would recommend. Update 5/31/25. This little amp is the bomb, no distortion at all in system everything is crisp no hiss. Have my gain set at 3/4. Would definitely buy again.

this little amp is just AWSOME. installed behind a seat of a 2024 hyundai santa cruz and it sound great and no heat or sound issues while doing UBER. drove 12-13 hours a day for about 10. months now.!!! Highly recommond!!

I really thought that this app wasn’t gonna do very much for me but I stand corrected. This little powerhouse literally allowed me to eliminate two other amplifiers on my motorcycle great stuff very impressed. The quality is impeccable

Has terrible sound quality and clips, shuts down. Our 400 watt Rockford does a stellar job. We're riding a road King with 8 speakers. The bike is built and loud. I can't hear the music with this amp. I can with the Rockford.

Put it in my rzr running the ds 18 8 inch marine speakers , clear , and very loud , it screams , definitely the best amp I’ve found for a cheap setup that sounds great

The amp rocks, put it on a 2016 street glide special with 4 speakers and it rocks!!

It is very small and it ran very hot. It sounded fine then the #1 channel started acting up. Doing crazy things if rca was plugged in. It is like it got connected to the other channels directly. Amp played fine as long as you only used 2, 3, and 4. Probably just a freak occurrence and I would purchase another but I am buying next size up next time.

Great amp. Fits in small spaces and offers good power for the price. I push 4 6×9's with it no problem. Good value for a budget 4ch.
