Product Details

BOSS R3004 RIOT 1200 Watt 4 Channel MOSFET Car Audio Amplifier

If you're still using your head unit for amplification, you have no idea what you're missing! Head units are often unable to provide the loud, dynamic sound you want, and can distort (or even damage) your speakers at even medium volume levels.

That's where the BOSS RIOT Series of amplifiers comes in. Tried-and-true Class AB amplifier topology, 2-ohm stable (for powering a pair of 4-ohm speakers off a single channel), and way more than enough power for even the hungriest door, dash, or deck speaker. The R3004 can also be set up for dual 2.1 (dual tri-mode) use to power two pairs of stereo speakers and two mono subwoofers (passive crossover values are listed in the manual). 

BOSS built the RIOT Series amplifiers with advanced features that are usually associated with amplifiers at more than twice the price: thermal and short circuit protection, soft turn-on circuit, remote turn-on/off, nickel-plated low-level and high-level inputs, LED power and protection indicators, all housed in a stealth black anodized aluminum chassis.

The R3004 also includes a MOSFET PWM power supply (for 4-ohm bridged-mono operation), dual variable 35 to 160 Hz low-pass crossovers, dual selectable fixed 80 Hz high-pass crossovers, a variable 0 to 18 dB bass boost, and a remote subwoofer level control for dialing in the perfect amount of bass from the driver's seat. Mounting hardware included.

Specifications: • Power output: 4 x 110W RMS (@ 4 ohms), 4 x 300W max (@ 2 ohms), 2 x 600W max (4 ohms bridged-mono) • Frequency response: 9 to 50,000 Hz • Signal-to-ratio: >102 dB • Total harmonic distortion: 0.01% @ RMS power output • Damping factor: >125 • Dimensions (L x H x W): 10.44" x 2.25" x 12.36".

BOSS R3004 RIOT 1200 Watt 4 Channel MOSFET Car Audio Amplifier
BOSS R3004 RIOT 1200 Watt 4 Channel MOSFET Car Audio Amplifier is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Not be top shelf gear, but it's NOT at all junk...THE BOTTOM LINEPros:-clean power within the RMS rating (which IMO is accurate)-Looks pretty nice-Build quality is great for the price-Drives subs nice and clean, and could make a good fullrange amp-Makes a solid 400w RMS amp, and is still a great deal!Cons:-Inflated wattage rating makes knowing what you are really getting (besides the fact that you know it's cheap) unclear.The Rest:I bought this amp in the summer and ran it for a few months. Unfortunately, I had to park the car it's in until I could get a motor for it lol. Also, I have only used this for powering subs, so I can't comment in depth on it's full range performance. However, the small bit of testing I did in fullrange left nothing to complain about. Certainly beat most headunits I've heard... Having said all of that, I am really just posting this long of a review, because there are no reviews here, and I had wished there was when I was committing to buy this thing... I mean, BOSS? I wasn't sure either. Most of us are looking in this range because we have to. But, if it's utter garbage, then I'd like to know! SO, here's what I can share about it:Power/Performance: Ok, here comes a bit of information I've learned on power ratings, and it may help you shop for amps with a bit more confidence, since brands don't tell everything about a product much anymore. I don't really trust the numbers on Boss' amps so much, nor Pyle and the like, but that is not to say they aren't good amps, they are just rated for marketing perhaps. But do you really expect 1200 watts for under 100 bucks?! Ya, me either. Then again I have not taken any real measurements. Using (fuse size) x (voltage) x (efficiency of an A/B amp) would maybe tell you SOMETHING about real world power at least. So in this case 50A (2 25a fuses)x14.4x0.6=432 watts... and that is perfectly consistent with the RMS rating published here. I did the same calculation for my Alpine for which i trust the ratings, and came up with the same numbers as Alpine's manual. So, 400w RMS and 800w peak is the rating I would stick with, and is STILL great for the money! So, is this a 600/1200 watt amp? Don't think so. 400/800 watts? Yes, and a good one. The performance of this amps is very consistent with those numbers in my opinion... On a practical level, any more than this amp, and you may want to upgrade your alternator anyways, and if you are plunking down that kind of cash, what are you doing building on budget amps? I have a second amp rated close to this, in the same car (the Alpine) and a factory alternator. When you end up killing your alternator from overload, you better get the replacement with the lifetime warranty, cause you'll need it eventually. Take it from the guy who swapped his 2 year old one out on a 17 degree day in the parts store parking lot. May take my own advice some day... So no SPL competition winner here, but if you're looking for some serious kickdrum in the back without such a kick in the wallet, this will make you happy!Build quality: The build on this amp is actually quite good it seems. It weights about as much as it should for an A/B it's RMS rating. The controls, and terminals work well enough. When I unboxed the thing, I did not get the feeling that I was unboxing a toy at all. Honestly, I came into this with low expectations, I just needed something to move some air, so I could get my rear speakers off the head unit, or maybe play with tri-amping the font, and ditching the rear speakers altogether (which is what i've done per a friend's advice, and it sounds SOO amazing!! I'm in love! lol). In the finer details, the overall build isn't as nice as the $pricey$ brands, but there is nothing here I can really take issue with. I still feel like I will get all the years out of this amp that I need, and not be wishing for something different the whole time.Features: I do wish this had an adjustable high-pass, but it does have one, and it is really a pretty ideal setting, for (at a minimum) keeping your fullrange speakers from getting shredded and cooked. The low-pass is perfectly flexible, and works just like it should for driving a sub in a clean manner.Sound: Like I said above, I have not used this as a fullrange amp much at all, only because I wondered if it was any good for that, and it was just fine. It did not stand out as a junker, and did seem much better than my pioneer head unit. For subs? I can say it really was a major improvement for me. I over doubled the RMS power going to my subs for less than 100 bucks! I don't have to beat up on my wonderfully clean but old (15+ year old) Alpine anymore, and can finally after all these years ditch the chip amp in that head unit! It really does a very nice job driving to subs in a clean and controlled manner. Far more controlled than what I had, just because now I can stay well within the power range of all my amps. But, within it's true power range (which will melt my current subs before i exceed it), it is as together as anything else! I mean, if I threw a couple of 12s in there, or whatever, I would have a hard time not being rude in town! It delivers clean strong power with out question! I mean, for anything on a practical level, this amp will no doubt, have you coved, and pretty well into the impractical rear-view mirror shaking realm as well if you want it...I think any amp in this series would be good. As long as you stick to the RMS power rating (which does look accurate to me) for your system build and expectations of what you are paying for. This amp, I am happy to report, to is a sure winner! If your not building comp audio, don't need thousands of watts but still want serious kick for those "because I feel like gettin' loud right 'bout now" moments; this amp will serve you well!Have fun!
