## Overview

The Rockville dB55 is a 5-channel car amplifier delivering 4000 watts peak and 2000 watts RMS power with CEA-compliant ratings. Featuring advanced Class AB+D technology, fully adjustable crossovers, and robust protection circuits, it offers professional-grade sound customization and reliability. Designed for 2 or 4 ohm stable setups, it powers 4 speakers plus a subwoofer with precision and clarity, making it a top contender against premium brands at a value-driven price.

## 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: 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
Review: If I could give 6 stars? I would. - 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.

### ⭐⭐⭐⭐⭐ Does what it is rated for.
*by Z***N on 13 January 2026*

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.
