Rockville dB55 4000 Watt/2000w RMS 5 Channel Amplifier Car Stereo Amp, Loud dB55 4000 Watt/2000w RMS 4 Channel Amplifier Car Stereo Amp, Loud!!

This amp is great. I expected it to be decent, but not as good as what I got. But I was definitely happier than I expected I'd be. So far no problems. Came with extra fuses, three of them in fact, which is brilliant--easier than having to go to the store to buy more if one or all of them pop, or waiting for a shipment of new fuses, even though fuses can be found it packs of ten to twenty for nearly $5-$10 and are cheap to buy new ones. Anyway, I replaced the poorly made, unorganized, severely bottle-necked set of amps I had before, (which I got from somebody, and hadn't taken the time to make it right or make it organized because I knew I was getting a bigger, better amp soon, not knowing which one until I bought this one--the picture of my old setup is up above, there are three amps... a Rockford Fosgate, a Dual from Walmart, and a Boss amp.. terrible combination.); I replaced that jumbled mess with this amp, and while I was at it, re-did all my stock wiring and even the old wiring for the old set of amps, which ran off of 8 gauge (or 10g? Can't remember) wire which was beaten up, tangled, unorganized, bottle-necking, and dirty. Now I have clean power and a clean, organized install with all the excess wire hidden away and zip-tied together to keep it from tangling or getting unorganized in its hiding spot. In the images I have, I had not installed the amp rack yet. In fact it's not even built yet but I will be building it soon. I will probably need decently thick wood however, this amp is nearly 2 feet long and 3 quarters of a foot wide and about two inches tall, and made of a combination of the metal and whatever else, and weighs a decent amount. I did a self-check on the power and I got mine to do about 950-1000 watts RMS per channel (bridged at 1ohm, stable), and it pounds. I'm using a single Sundown 12" E-12 D4 dual voice-coil (500w RMS per coil, so about 1000w total--and Sundowns are known for being very underrated) and it fits the sub perfectly and pushes it hard. Very noticeable difference between my $200 - 400w Rockford Fosgate. In fact, my Rockford Fosgate amp is old and would cut out on me, going into protect (just because it was old and the original owner must have done something to make it unstable) after about half volume even with the gains completely down, and a good ground, and at 4 ohms per channel and with everything else down. Overall, AWESOME amp. And a huge amp for its price.

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

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.

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.
