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.

    • 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. ... show more

    • Sooo satisfied with the quality sound and power.
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. ... show more

    • My 3rd Rockville amp
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. ... show more

    • Great amp, a must buy for novice audio enthusiast....
Great amp for the price. Provides the CEA wattage that is advertised. This is the second Rockville amp that I purchased. Both amps run hot and if ran at full volume for a long period of time it goes into protection mode. If tuned down run perfect with no problems but still run extremely hot. They need better ventilation. I added fans to help with the heating issue. Overall great amp for the price. I am running infinity 6x9 and infinity 6 1/2 at 4 ohms not bridged, and a single Rockford r1 at 4 ohms. I do live in Texas and have 100 degree days. Update.......... Replaced my subwoofer with the 12" Rockville 600 rms subwoofer. I am running the subwoofer at 2 ohms. The amp states that it pushes 500 rms at 2 om's. I am not able to run my 6 1/2 and 6x9 infinity speakers and the sub with more than half the gain because the amp starts clipping. The amp does not have enough power to push this setup. Still load enough for what I wanted. But like I said, I'm only able to use half the power the amp says it's rated for. With that said I change my rating to 3 🌟 s ... show more

Wanted to upgrade my car audio, did some research, not a whole lot but came across this for my budget on a amp at the moment. Got new speakers. Pioneer ts a653ch component speakers in front and pioneer ts a683fh in rear doors in my 08 mazdaspeed 3 hatchback all wired to the amp. And single sub in hatch. But I'm going back and forth testing subwoofer rn. Got a 12 JL W0 300rms @4ohm and a 12 kicker comp r 500rms @2ohm I'm switching back and forth to see what I like better in the ported box I got. Ordered and Waiting for my sealed box to see if I like either of those in that better. But biggest thing I seen people say about this is it gets hot. I have mine turned up on settings and live in Florida it doesn't get very hot for me. Just mount like I did and mount it to get air circulation. 1 inch spacers maybe 3 bucks. 2 pieces of wood like 20 inch long and some screws to match. I think I paid 12 bucks to mount mine to back of seat. I like it. No issues yet and pumps enough power to everything. Also not trying to blow down the block. ... show more
