I have had this amp for almost a year now, I have it paired up with 2 12" Alpine Type R's in a ported box and it pushes them to the max. I have had people asking if i had 2 amps running the system and i only have the amp tuned about 3/4 of the way up. I would highly recommend this amp!!!!!!! Definitely going to get new ones when I redo the system.

I'm updating my previous review due to some changes i've made to my system. My digital designs 3512 sc subs are now broken in. I have two brutus 1700 amps driving the two dvc 4 subs, coils wired parallel, amps are being presented with 2 ohms each. I can't say enough good things about these amps. My system is intended to be competition level and it's almost there. The most recent spl check was 154.3 in a '09 silverado ext. Cab without the rear seat.

For all the people i'm seeing that say hifonics amps are power hungry and their lights dim when the bass hits blah blah blah. You do not start building a system by throwing two huge amps and two subs in a car and go from there. Upgrade your charging system first! You can't expect to blast 1,700 watts off a stock alternator and 4, 6 or on some foreign cars, 8 ga. Charging system cabling. I have two yellow top dura last 1100 cca batteries and a stock hd 160 amp alternator and i have no problems driving two brutus 1700's and a zeus zxi150.4 (1,200 watts). No problems at all. I have gains set properly! This means doing the simple math to convert expected wattage output to ac voltage and setting the amp gains to that number using a test tone with your head unit at reference volume! If you don't know how to set up an amp, get some help! These brutus amps are awesome. And Sonic is awesome. I order on a Monday night and i have boxes on my step by wednesday when i get home from work.

I bought this amp a few months ago and man do I love it! It's so heavy and the only downside to it right now is that I only have a stock battery/alternator so I'm sure I'm not getting the most out of it! WORTH THE MONEY!!

I had the Hifonics BXi2010, which was a good amp but only lasted 7 months then went into protect. I have 2 Alpine Type R 10's & im running them @ 2ohms. I now have the BRZ1700.1 running @ 2ohm's & this amp is much louder than the BXi2010. The BXi might have been faulty & not putting out the 1300 rms @ 2ohms, but this BRZ is putting out at least the 1200 it claims....I highly reccomend for the $$

I had A crappy lanzar vibe amp I got at the flee market at full power hooked up to two Alpine Type R 15 in a ported box in my truck. I was looking for something with more power and damn, this amp pounds my 15s hard! My rearview mirror shakes off and parts of my truck are rattling apart. Good value for under $300 out the door(with tax). highly recommend this amp. Never heated up, not once. Blue illumination looks nice at night.
- Dont have capacitor? GET ONE. You will need it.

I had amp 1608d 1610d and now brz 1700d u can tell the difference between thees amps. 1608d and 1610d were good amps no problems. The brz line is way better . I got this pushing 2 kicker l7 12s in a 6 cubic foot box tuned at 40 htz . And all i got to say is amazing!!!!!!!!!!!!!!!!!!!!. Buy this amp its worth it . If u feel like the amp is not putting out properly upgrade your wiring. Also add a yellow top battery and maybe a high out put alternator. And then see what happens . U will be impressed

I love this amp it works and sounds great i would buy more if i need a new amp.

I bought this amp to power my 2 10"eclipse subs, and it is perfect. Never gets hot or even warm to the touch. Has everything you need. Awesome amp for the price

I would tell all my boys to get this! But please listin to the ratings if your sub say 300watt rms find an amp thats for that sub if it say 600watt rms wire it to the specs or else u wont have your sub anymore I had an punch BD 1000.1 an this is cheaper an hit harder if u kno what your doing so join the band wagon if u want to beat your town up much luv Hifonics an Sonic nobody beats U!!!!

Great amp! im pushing two alpine type r's and they just sound fantastic (my car sounds like its going to fall apart) i would recommend it for anyone who wants a good output with a lot of power!

Running this @ 1-ohm to a Audioque HDC3 18" (Dual 2) & it gets LOUD. Runs nicely & hasn't gotten hot on me, yet! Love the bass knob & blue power lights! I'd recommend this to anybody looking for a nicely priced amp that puts out some power!

I love it cea compliant and it doesnt break your pockets. I have two of these and I have had them both for a year beating the crap out of them and they are still running strong. Great product would recommend to anyone.

this amp is worth every dollar, I'm pushing one 15 inch solo baric L5 with it.

I have been pleased with my service. At 1st i ordered the wrong amp and i had no trouble returning it. They have been very helpful.

I've been a fan of Maxxsonics for years, so when I rebuilt I decided to pick up this little beast.....I love it! plenty of power, does well over rated power, looks amazing, etc. It was recently replaced due to it just not being big enough for the application I had it in (I.e. needed more power lol) But it is still an amazing amp I would recommend it to anyone!
Only reason I rated it down on ease of use was the stupid angled power/ground inputs, so difficult to get 1/0 into while mounted.
(Also, to everyone talking about heat issues, I ran this amp at a 1 ohm load in 110 degree heat full tilt on low voltage and it never broke a sweat, you were probably clipping =P)

Excellent Amp. Does rated power and doesn't get hot. Would recommend!

I've only owned this amp for 2 days..i have it hooked up to 2 Re Audio SEX 15s DV2 and before this amp i had a Alpine Mrp-500 hooked up and this amp blows the alpine away..by far this is the best amp i've owned. i have it running at 2 ohms and it barely gets warm.

This amp puts out exactly what it is rated at, my only problem is that it keeps over powering my subs. I just blew the 2nd Orion XTR12 @ 2 ohm and had the gain turn up to about 40%. I live in Texas and even when the temp is well over 100 degrees this amp has no problems.

The frame of the amp is plastic a bit cheap but that is the only con.

I love this amp it pushes my type rs amazingly had it wired to 4ohms and was at a bass comp did 136.8dbs sealed prefab box it flexes my hatch and my windshield in my camaro with only round 600 watts get this well worth the money.

I bought this amp to power a kicker L7 i had in a SPL box tuned at 40 hz. It was an awesome amp on that setup, and it hit quite hard. I sold the kicker and got two Skar VVX-15's and it hits even harder, the lows are perfect and it shakes the roof so much that people want to lay on it. I would recommend this amp to anyone who is a bass head like me.

This amp does what it says. Ease of use has been lowered because of sharp edges and strange angle of power terminal; however this angle has been designed for the mounting of the amp. Performance is top notch. I know that some people knock on this Brand; still can't figure out why. I have owned several higher priced amps with the same power rating and get the same performance. I think my brand is Hifonics.

I have this amp pushing 2 12" type r in a civic and they pound. Take in mind the amp is at a 2 ohm load so I don't blow the speakers. Can't wait to get new speakers that will handle 1700 watts. I have upgraded battery to a yellow top, high output alt and a capacitor. I added the cap because I fried the alt. For the money u won't find a amp with this much power. I love it. I have had it in for at least 6 months. And I have it cranked up to and from work 40 min. Each way holding up great.

i have this hooked up to 2 apline type R 2ohm with 160 amp alt. , stock everything and 0 gauge wiring.The amp does what it says it does, my current reading is 1040 watts since i cant run 14.4 all day and it never gets hot, its crazy how much it can push these subs. now i have a stinger battery, did the big3 and put sound damping material through the trunk, now it SLAMS, i keep a consant 14.6v and now im pusing 1300w all day!!!

I bought this amp from a dealer for same online price and i have 2 15" hifinics brutus subs with a 4.8 cf box ported btw and man this amp made my subs shake other car doors next to me. No lie my roof was flexing a half inch. Great true 1700wat amp.

It's an easy connect hook up no fails, pushing my sub just right, would recommend this to anyone.

I have had this amp for alomost a year now pushing to 12" Kicker CVX's at 2 ohms in a probox and it absolutely slams! Great amp! I would recommend to anybody, people ask me all the time if I have 15's and I have been told they're louder then 2 15's.

I love this thing i was told its top of the line well i can back that up it is friggen amazing. It sound 10x better then my other amp AAAAAAAAAAAAAAA+++++++++++++++++++++++++++

I just got this amp and hooked it up in my PT Cruiser to 2 12" subs with an extra battery and a volt meter. This thing will pound your subs into oblivion. Be careful of the fins though because they will cut you open in a second. For the price, what you get, and the quality of Hifonics, these will be the only amps I buy from this point on. AMAIZING. Cant say as far as durability because I have only had it 10 hrs but it has already been dropped twice. The second time on the frame of the inside of my car and never missed a beat. Thanks SonicElectronix and Hifonics for a great product!!!

In the past I swore by Rockford Fosgate but thought I'd give Hifonics a try. All I can say is what a fantastic product. I'm using this amp to push two DVC Cerwin-Vega Max subs. It produces crystal clear accurate thump. The amp has never cutoff and hardly gets warm at 2ohm. I considered adding a 3rd sub to get down to 1ohm but I'd like to keep my rear window.

The only knock on the design is the heat sinks. They have sharp edges and will cut you if you're not careful.

Overall this amp is amazing, i have it pushin two 15 kicker cvx. Through the whole town im told i can be heard well over 5 blocks. Only problem i have found is it grounds out a lot just make sure to find a large enough ground that will fix it. Also has quite sharp edges use caution when handling.

Good, heavy, solid excellent amp. Bumping the heck out of two 6Ohm 10" DVC Audiobahns. Amp is running @ 1.5Ohm Mono and flexing the heck out of those Audiobahns. Love it.

Thank you Sonic Electronix for the excellent customer service and ease of exchange transaction! Great customer service!

I originally had a rockford 2000.1bd on 4 kaption spl 12's until the amp fried. I wasn't looking to spend a lot of money so i took the chance and ordered two of these just in case I needed both. Little did i know i would only need one! This amp pushes harder and better than my old Rockford. I definitely give it 2 thumbs up!!!

AMAZING amp... i'm running 2 Obsidian 18's off it at 1 ohm and even with stock electrical it still puts out TONS of good clean power and never gets more than warm enough to tell it's been on. i've been a fan of Maxxsonics for years and i'm quite happy with this amp.

I returned the Planet Audio amp for this one because it was too big and went off the measurements posted but I still ended having to remove the side's that are used to bolt down the Amp on this one. No worries, doesn't mess with the heatsinks and you can't get to it w/out removing 4 big bolts.
Any how the build quality seems solid and it's a hefty Amp. Thus far it's rock'n my 2 10" DVC 6Ohm subs. Good Amp so far. Thx Sonic for the easy transaction and excellent customer service!

So I had to return the Planet Audio because it was too big and I got this one. The measurements said it should fit (in comparrison to the Planet Audio measurements) but I had to take off the sides that you would normally use to bolt down the Amp (not the heat sinks of course). I've been using it for a few days and it seems to be rock'n those 2 10" DVC 6Ohm subs. I need more time to tweak the Amp settings but I'm liking it thus far. The Amp build seems pretty solid and it's a hefty Amp. I can't really comment on the LED that lights up because it's behind the back seats in my Dodge RAM quad cab. Any how it's getting the job done for sure!

Fantastic amp. Worked well driving 4 Alpine 12s and also works on just 2 little 10s. Great all around sub amp.

This is a great amp, buy it. It is phenomenal.

This is a great amp. I have it pushing two L7 15's and it does a great job. I can play my subs hard for any amount of time and it never even gets warm. Definitely worth the money

This amp pushed alot of power and was pleased with this amp. never had any problems with it what so ever and for the price it's a steal I would recommend this amp to anyone or any hifonics amp to use. These amps push power!!!!!!

What a powerhouse. I have this powering a Pioneer 10" Premier and it powers it hard for my 10 hour rides home from college and when I get home it isn't even warm. Ridiculous power and the lights are awesome. Definitely worth the money. Very high quality considering the price.

I had the same amp but an older model for over 5 years one day it just went out so I order a replacement this one is even more powerful, Love it... For the money you can't find the same amp in the same class anywhere...

I had this amp wired up to 2 jbl p1222's and a pioneer 3002d2 (1.33 ohms) and it pushed them to their limit. I used 0 gauge wire with a shuriken skbt60 to supply the power. I would recommend this amp to anyone who needs a lot of power as long as you give the amp enough power.

I've owned pretty much every brand of mono block amp, and as far as the money/ output ratio very nice product!

I bought this amp cause of my friend it pounded his two sundown sa 12 like there were nothing. Takes alot of power. I got my to sundown sa 15s running at .5 ohm which this amp is not stable for but have not had a single issue with it heating up, clipping. But this amp is POWER HUNGRY SO have a cap. But i would use a battery.

Only had it for a week but it pushs the hell out of my 3 ( 12s ). Great power for the money , can't beat it.

Well I bought this amp about 6 months ago and I am very pleased! It really puts the power out that it is rated for and may even be underrated! I have it running at one ohm to two kicker 15" l7's and they are getting all the power they can handle. I have never been more pleased with an amp and I would reccomend it to anyone! The price was fantastic and sonic shipped it right away! Definately a home run!

This amp is definitely worth the price. If you want to be heard from a mile away get this amp. I have it hooked to two P2 12" Fosgates and nobody can compete with me. Everybody always ask me if I have 2 15's.

I highly recommend the Hifonics Brutus 1700.1. I have it pushing my 12" kicker L7 and it doesn't get hot when turned up all the way. It hasn't skipped a beat and sounds terrific.

I have this powering an RF T2 @ 1200w rms, and it makes it slam! I did my homework before buying this amp, and i can say its the best bang for your buck hands down. I've had it running for about 5 months.

Finally here to write my own. This thing is nasty. started off with it on 2 600 watt american bass 12" @ 2 ohms 1200 watts. Reeediculous! killing my mirror, breathing trouble and all. Threw the 1000 watt pioneers on it, didnt realize it was still @ 2ohms and still.. oh my god.. went out this morning and dropped it again. HOLY F***!!!!! And the volume on 12! amp is up bout 85% + now since I broke them in at 1200 watts for so long (few weeks). (now remembering i hated long reviews)

Pros: great price for the power, looks good
Cons: sharp edges (dont ignore like i did), Poower huuungry!!!. New alt 105 amps old battery says 12.5 on meter, big 3 with 0 gauge and i still dim in my 98 mc z34. Overall I am very pleased with what I see and hear being a beginner in car audio.

I've had this amp for a year and I love it!!!! I have them hooked up to two Hifonics Atlas 12's at 2ohms. It powers them very loudly, clear, and hard! It has great durability, during this past winter i came out to my car and found the amp coverd in frost. I turned it on and it worked fine then i let it thaw and dry and it kept working.

PRO's: Comes with a bass knob, looks great, great build quality product made by maxxsonics!

CON's: goes into protect when revs up an makes a 16volt pulse, 2AWG power and ground terminals.

I would recommend this to any one who want a great amp that produces a loud and clean bass signal.

Great buy. I love this amp, great price.

Pure power boyz! Have tried kicker amps and they just couldn't hang. The Brutus rules over the rest!

This amp is a great amp has been great for the 6 months that I have owned it. It is powering my 2 12" L7 kickers and they sure do get enough power that is for sure. It has a great display of the Hifonics lettering that light up blue. The price was right with this amp as well and very much so worth the money. I would definitely recommend this to anyone who is looking for a great class D amp for a decent price.

This is a great amp for the price! This amp has a lot of power only if you have the right hook up! A kinetic power cell battery you will need because this amp requires a lot of power i would recommend a 2400 kinetic power cell. Great buy! Highly recommended! By the way this amp has never overheated, a little warm, but not really warm!

This amp is pushing my JL 12 W7 and all have to say is bad ass amp it does all and more!

I have two of these amps powering a pair of Digital Designs supercharged 3512, DVC 4s. I have installed car audio, and designed and built enclosures for over twenty years. The enclosure I designed and built for this set up is 5.05 cuft net with 80 sq in of port area that's 26" deep, which tunes at around 35 hz. The system is in a '09 Silverado Ext. Cab. I chunked the large part of the back seat for the enclosure. I have 2/0 cabling on the "big three" (in my case "big four + two"), two Dura Last gold top 1100 CCA batteries (IMO the best gold top value available at $110 ea.), a stock HD 160 amp alternator, and 1/0 power cables to the amps.
Now for the good stuff. Each sub is presenting a 2 ohm load to it's amp. These amps are rated at 1200 watts @ 2 ohms, and let me tell you, they are both doing that with ease. When I made the initial adjustments to the amps, I set the gains with an output of 49 volts AC (which is the close equivalent to 1200 watts) on a 60 hz test tone. Amp #1 reached rated power at the eleven o'clock position amp #2 reached it at the twelve thirty position. I knew right then that these amps would rock. THESE AMPS TURN MY DD SUBS INSIDE OUT! I've cracked two windshields and had so much roof flex, it would bounce a quarter off the center of the roof on the first hit. I subsequently pulled the entire interior out and laid sound dampener covering every square inch of sheet metal from firewall to back of cab, floor to ceiling, and door to door. Now it takes three to four hits to bounce a quarter off the roof. The subs and amps are running off a Pioneer AVH-P4300DVD head unit. The HU is powering a single set of Kenwood Excelon component 6.5" mids/tweets (for now). Once the subs were broken in, the system was metered with a competition judge's calibrated meter at 149 db, far better than I had hoped for. I'm pleasantly shocked with the performance of the two Brutus 1700's. To be honest, my system build is still in process and I originally purchased the two Brutus amps just for something temporary. Once I had the system completed, I had planned to sell the Hifonics amps and purchase a pair of Rockford Fosgate T-1500 amps to go with my subs, which are conservatively rated at 1500 watts RMS ea., but not now. I love these amps. I bought both of them for less than the price of a single RF T-1500 and they routinely turn my subs inside out. I've run the system extremely hard, at reference volume for 45 minutes and the amps remained cold to the touch. No hiccups, no failures, nothing. I sang the praises of these amps so much, a friend purchased one. He inadvertantly connected the power and ground cables backward and tried to test the amp. He said it sparked a frankenstein spark and he quickly shut the power off. After a sleepless night from thinking he had smoked his new amp, he got up the next morning and wired it correctly and it played without a hitch as if nothing had ever happened. Try that with an RF amp. I had also planned to install a RF T600-4 for my mids/highs but I love these Brutus amps so much, I purchased a Hifonics Zeus zxi150.4 (150 x 4 @ 4 ohms, 300 x 4 @ 2 ohms) to power them. Next up, after installing the Zeus and two new sets of KW Excelon components, I plan to install one more sub spec'd the same as my first two and, of course, another Brutus 1700.
BTW, every single piece for my system (except the subs) came from Sonic. Never a problem with a shipment or a product. As cheesy as it sounds, Sonic is my new home for car audio.

Great amp would recommend.

This amp is a beast my cousin has it pushing 2 1000 watt rms 15" subs and they are way under powered and this thing sounds like its pushing the max. This is a beast, soon when i upgrade this is the one im getting or the 3000 watt one not sure.

I bought this amp a couple weeks ago and have it hooked to two brutus square 12's wired down to 2 ohms in my truck. They hit hard and the amp never gets hot. Great amp for the price.

I bought this amp to push my 2 Rockford Fosgate 12" T1's, it pushes them very nicely and is overall a good amp. I ould recommend this to anybody for the price you can not beat it but at the same time i had a fosgate T1001bd mono amp and that thing was beast kinda expensive but BEAST.

This amp is pushing my two Rockford fosgate T1's and it pushes them with no problems good amp and I would defiantly recommend only thing negative is the amp material it's really sharp and seems if it could cut you lol high quality though for sure.

I'll start out by saying this amp is awesome!!! Although I did blow quite a few subs already so make sure you don't cheap out on the warranty for your subs. This thing on the other hand is rock solid awesome design and is most deff puts out what it say's possibly more. I just have to get enough money to buy another sub. I'm currently using 1 4ohm Alpine Type-R series dual voice coil sub. It's currently running 8ohms until i put on another sub which will make it 2ohms. Much more power.
