## Overview

The Rockville dB55 is a 5-channel car amplifier delivering up to 4000 watts peak and 2000 watts RMS power with CEA-compliant ratings. Engineered with advanced MOSFET power supply, adjustable 12dB/octave crossovers, and full IC protection, it offers professional-grade sound clarity and reliability. Designed for 2 or 4 ohm stability, it includes a remote bass controller and subsonic filter, making it a top-tier choice for audiophiles seeking powerful, distortion-free car audio performance.

## Description

The dB55 is a 5 channel high power amplifier with 4,000 watts peak output, 2,000 watts RMS output, and 980 watts CEA-2006 rated power. Here at Rockville we offer the best value in car audio. We therefore want to make it easy for you to compare our products to any brands on the market. So we provided 3 ratings for all of our car amplifiers. We provided a CEA compliant rating, which you should use to compare this amplifier to other premium brands that make CEA compliant products such as Kicker, Rockford Fosgate, Kenwood, Pioneer, etc. We also supplied an RMS rating that is not CEA compliant, but has become standard in the industry. You should use this rating when comparing with ratings from brands such as Hifonics, Earthquake, DB Drive, etc. Lastly, we also supply a peak rating which almost all brands in the industry provide. This peak power is the amount of power the amp puts out at the loudest moments during a particular song. This amp has a fully adjustable 12dB/Octave crossover with differential circuitry. Other features include a subsonic filter, a fully adjustable bass equalizer, and mute and delay soft start technology. The dB55 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free music playback at all levels. The dB amps by Rockville use the top parts and components recommended by Rockville’s very own engineer. These amps are the best sounding out of any series we have ever created. They perform more efficiently resulting in even dB of sound. We created them to be 2 ohm stable just like the world’s most famous amps by Rockford Fosgate, Kicker, etc. If you compare our amp to the most famous amps you will find our amp can compete and, in my opinion, surpass the performance of anything in its class.

Review: Awesome amp. (2800w peak version) - 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.
Review: pretty darn good - 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

## Questions & Answers

**Q: Are these 0gauge inputs or 4gaude?**
A: 4 I believe, 4 fit perfect in my sons car.

**Q: With this 5 channel amp , can I hook up my highs , tweeters & subwoofers at the same time?**
A: That's the whole point of a five channel amp.

**Q: Would this amp be good for 6 speakers i wanna use it for highs**
A: This amp is terrific for miss and highs being a class A/B amp, however your gonna be a channel short but I'm sure there is a wiring diagram through crutchfield you could use to figure something out

**Q: Would this amp power 4 6x8s and 1 sub??**
A: I would recommend getting a separate amp for the subwoofer. this amplifier runs hot if you push it at two ohm's. So depending on what kind of rms wattage is needed for the speakers that you are getting it might not work for you. I was running Infinity 6x9s and infinity six and a half with the 4 ohm subwoofer a Rockford fosgate r1. The subwoofers rated at 150 watt RMS and I had no problems with it but I upgraded to a Rockville dual 4 ohm subwoofer running at 2 ohms recommended at 600 w RMS and I cannot power the amp more than halfway on the game without it going into protection mode mode because of overheating. If you decide to bridge your 6x9. This amplifier will not work for you this is why I recommend getting a separate four channel Rockville amplifier. For the 6x9s and a separate Rockville amp for the subwoofer. The amp is a good amp for the price it depends on what kind of sound you are looking for and how loud. I would only recommend using this app in a 4-ohm application not bridged and not any kind of two ohm application

### ⭐⭐⭐⭐⭐ If I could give 6 stars? I would.
*by K***T on 7 March 2022*

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.
