dB55 4000W 5-Channel 2-Ohm Car Amplifier, High-Speed MOSFET, Adjustable Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs

I went in on this with hesitation given some of the other reviews. I have been installing my own car audio since 1996. This amp went into my daily driver 2004 Trailblazer. The stock radio was trash, only one speaker worked. I installed a Sony XAV-AX8000 head unit and kicker 6.5 coaxials in all 4 doors. It was decent. At least all four speakers worked. I've never been a huge fan of Sony head units? But I got a great deal on it. I decided to grab up this 5 channel amp after watching an amp dyno video on YouTube. It seemed like it would fit the bill nicely to power my 6.5"s and a single 12" sub. I literally just finished installing the amp, the subwoofer isn't even installed yet. I'm hearing sound quality that I would easily compare to my JL amps that are installed in my other vehicle. I had a Hertz 4 channel a few years back and this really reminds me of it. If you set the gains properly, you don't try to destroy your speakers with it, and have at least a moderate level of knowledge in car audio install? (Clean ground, power down one side of the vehicle, signal down the other, properly sized copper wire for power) You'll be super impressed by the sound quality of this amp. My front stage (front area of the vehicle) is superb and this is only a daily driver. I can't speak to longevity just yet? But I'll definitely update the review in 6 months or so. For the price though? This amp is a complete beast. Completely satisfied with this purchase. Update: Hooked up the subwoofer which is a shallow mount 12" single voice coil, in a .7 cubic foot box currently. Not ideal for an SUV? But it still sounds robust and full. The amp has no issue pushing this 450w RMS sub, and I only have the gain set to about a quarter of the dial. This really is an impressive amp! When I finish building my downfire sub box with passive radiator, I'll update this update.

I purchased this product for over $200 in May 2024. Initially, I was hesitant because I doubted it could deliver 1000 watts of RMS power. However, I’ve been using it to power 100 watts of 4-door speakers and a 12-inch subwoofer, and I’m amazed by the clear sound it produces and the earth-shattering power. A year after my purchase, I decided to write this review. This amp has held up remarkably well. I’ve owned many name-brand amplifiers, and by far, this one surpasses them in terms of power and price ratio. I guarantee that anyone who purchases this product will be completely satisfied. I highly recommend it to anyone.

I have a DB14, and now 2 DB55's installed in my ride, and I couldn't be happier with any of them. I've owned RF, and Kicker amps in the past, and they're both good, but my Rockville's outperform both at a much more affordable price. If wired correctly, these amps run pretty cool even when i'm rockin out, they barely get more than a little warm. Having basically 2 amps built into a single box allows a new build to get up and running quickly and inexpensively as well as giving a lot of flexibility to an established system that you are adding to. I'm using my 2nd DB55 to bring out more mid bass and give a fuller sound to the overall system, and it is doing that flawlessly. Even the remote bass adjust knob is all metal construction and will last, unlike the plastic junk many of the manufacturers offer. I recommend the DB series amps to anyone looking for a great amp at an awesome price.

5 channel amp,good quality connections although I'd rather had ring terminals.the Allen wrenches r included for the spkr wires though,amp lights up that I didn't expect,works great with my tweeters and even the sub sounds better then my old amp ever did and it was a much higher quality name amp.some have complained of it going I to safe mode but mine hasn't yet and I do crank it with ny t tops off but I also am running a capacitor for extra power to not drain my alternator and making the system get got.im running a kicker 10in sub and 4 alpine speakers and 2 alpine tweeters.with the gain adjusted properly on amp I can turn my android radio up all the way and no distortion at all which is way to loud even with windows open and tops off.will I am running 2ohm speakers and it sounds great.make sure all youre positive go to positive and vice versa for the ,evasive wires.that really makes a difference and doesn't damage you're sysyem.in apx another year when my other car is done if this one seems to be holding up I will probably get another one and or the next step up model they have.i like I can turn it up and feel the music as well as just hear it with no distortion or over powering my speaker system.id say if ya crank it and get distortion in speaker you are over powering the speakers you have in car so either turn the amp down or get better speaker system.i run oversized speaker wire and they are soldiered to my speaker for great connection and very little resistance.There are some actually good videos of set up on there website to watch as im sure not many do but if ya do what the guys shows ya you will have very little.problems with the amp setup.takes awhile to perform all the checks he is doing but if done correctly you will enjoy a pretty good sounding amp for under 290 bucks.my old amp was closer to 800 bucks and I burnt it up after apx 3 years maybe.nainly from poor quality inside.id pull the rca Jack's out to do something when I was changing speaker amd the terminals inside amp came out alo.oulled the fuses to male sure no power to amp even though I disconnected the main fuse and the fuse terminals came out from being hot.Just wasn't a well made amp for the money! Voltage draw is less then my old amp also and seems to run much cooler then my old amp.So just don't expect options from a 1k amp or more on this 290 dollar amp and you won't be disapointed.i also really like the quick start when it's turned on and not a second or maybe 2 delay my other one had.4 star rating is pretty high rating for me to give as i.prerty picky and a 5 start one would be like a $1500 or more amp with more options so you get what you pay for but for the money this one so far seems darn good!

This is a great amp. Hard to beat at this price point. Very light and compact for the power output yet still feels substantial and of good quality. Easily powers an entire system with good quality sound.The options are good enough that this will never be obsolete , can fit somewhere in whatever setup you have and will perform admirably in any role you need it to fill well into the future. Good deal all the way around.

i got 4 speakers that are 110w rms 4ohm this amp does 80w rms 4ohm but it sounds good i also have a 1000w sub and i'm quite happy handles it super well just make sure you have a strong 4 gauge ground and 12V i also went with a 200amp fuse at the battery

Nice 5-channel amp. It does not have any built-in fans so you have to rely on external sources to cool it. The whole body acts like a large heatsink which makes it difficult to cool if trying to hide this into a small space. The only complain I have is with the Bass control remote and not the amp. The little blue LED power light on the remote was way too bright and it burned itself out within 2 weeks of installation. I am fine with it since the light was annoying me too much but I can see it might be a problem for someone else.

En temas cualitativos me hace extrañar un poco al JBL que ha reemplazado. Pero es justo decir que hace el 85% del trabajo con el 40% del costo. Vale la pena! Que no me gusta: las conexiones de bocinas, especialmente la del SW que es del mismo tamaño que el resto de las bocinas, son muy pequeñas. Eso hace que conectarlo sea muy laborioso. Es necesario subir a la parte alta los controles de volumen del amplificador, aprox el 80% para tener la respuesta del ampli anterior (un GTO 5500); pero no llega a la saturación tampoco. Tiene una estructura de plástico a los lados que considero innecesaria y porque aumenta el tamaño sin agregar mayor valor y eso dificulta su instalación si el espacio es reducido. La potencia del SW es muy adecuada y no se queda corto. Hasta ahora ha aguantado los abusos del alto volumen sin protestar. Tiene un timbre particularmente agudo (nadie escucha esto solo yo, es justo decirlo también) y pienso que esto sacrifica un poco la respuesta de los medios que, con un poco de equalización de mi DSP, queda impercetible... (al menos para todos los demás). Una excelente opción económica para tener un sonido de buena calidad.

El amplificador se bloquea a cada rato, no aguanta de volumen medio a volumen alto... se instaló con un profesional!!! Simplemente se para y a los pocos segundos Vuelve a tocar.... no gasten su dinero! Es muy mala compra
