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

    • First dabble with car audio.

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

    • You want this amp!!
I have purchased 2 of these at this point. I have had all the big name amps over the years, and spent many times the cost purchasing them, and this amp holds up to some of the best! The capability of this amp for the cost is unbelievable! I’m running four 400 watt rms 6.5” kickers and two Kicker CVR 12” subs with perfect clarity and response with crazy volume capability! My first one is almost 2 years old with hundreds of hours worth of bumpin’ on the clock and it is still perfect! This amp just can’t be beat for the cost! ... show more

    • really decent amp for the money and sounds very good after it was all adjusted for my system
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! ... show more
