Unsurpassed, price. And unparalleled quality. Ch

Solid 5 channel amp! Perfect amount of power for adding a simple system to a car. It has bells and whistles, like clip light, sub gain knob with clip indicator, and infrasonic filter. The size is a perfect small footprint. This it the best dollar per watt performance, per size. Only con: Considering the power, I was wondering why it didn’t have 1/0 gauge power and ground.

Tiene mucha interferencia (Distorcion) Crei que era el cableado lo revise cada cable hasta cada conexion y todo parecia bien. Aleje los cables vivos de los RCa y todo y no funciono al final uso otro amplificador que tenia ahi y me di cuenta que estaba bien no me daba distorcion. Es con el primer amp que me pasa esto no lo recomiendo y se calienta mucho

I have an old RF 25 to Life Power1000 that has a mostly similar output to this amp, however the G4000.5D is a quarter of the size, if not smaller. It's amazing how much power this tiny class D amp puts out. It may be tiny, but it is quite hefty and I love the understated matte black look. Running this with a pair of JL 10W6v2-D4 at 1 ohm and a quartet of BA speakers yielded amazing results. Very full sound from the components, subs hit hard and super easy install. The amp does get hot when pushed, but that should be expected as DS18 has packed a lot into a small space. I would have liked to have seen some larger terminals used for power and ground, but 4awg is mostly fine. This is the first amp I've installed with terminal attached RCAs and I didn't think I would like them, but it actually made the install a bit easier, so go figure. Overall, this is a solid and powerful amp. And it is small enough to install just about anywhere which makes it incredibly versatile.

DS18 has done a great job with this G4000.5 Gen-X amplifier. I've been shopping around for something to push the door speakers in my 2016 silverado after adding two sundown 12" subs under the rear seat. To test this I put this amplifier under the front center seat and re-routed the speaker wires under the carpet along with everything else. Super simple to set up if you are at least familiar with amplifiers and the 4 gauge inputs make it a lot easier to route than 0 or anything larger. First start up was a very noticeable change in the output of even the stock speakers and after some tweaking of the lowpass/subsonic filters this thing came to life. I cant really crank it up too much but on the lower power settings it is really impressive. I cant wait to add in some good quality tweeters, 6x9's and 6.5" mids and hear this thing really bump. Definitely recommend and cant wait to see what others can do with this thing
