    I bought this amp just wanted to test it out and not expecting it to work very long. When I first received it, it did not look or feel very bad. The amp itself feels sturdy and of some quality. When I hooked it up to my Massive Audio hippo series 8” sub I didn’t set the gain as high as I could’ve just to see if it would work and it did. I turned turned the gain up to where it should be and it has been running for 4 months without any problems. I waited to do a review to see if it was even worth my time and I’d say so far it’s worth it to tell everyone how it did. I think maybe some people with 1 Star reviews either just got a bad lemon or were trying to push too much with it. I’d definitely say this is for a simple set up, not for completion or any extremely high wattage subs. Overall my expectations were exceeded and hopefully this amp will continue to work. I will update this if anything else happens worth knowning.

    i am running a 1800 watt zuess amp at 2 ohms in my ford ranger on two 12 inch mtx aubs. it pounds hard and over rode everything else. i changed my 4 6×8 door speakers out and added this amp. i am running the high pass filter. talk about great! i listen to heavy metal music. i can now hear everything and it puts the bass in its place! i have bass cds to show off the subs. i can now hear the entire range and not just the boom boom boom of the fake magic drum rap music uses!!

    This amp .(cheap)2 pioneer 8″ MIDBASS speakers in backseat (mid price ranged )2 mid price ranged component speakers front door .All four speakers powered by this amp.Music sounds larger than freaking life. So loud you can lose your hearing . . . Also no distortion whatsoever.I just recommend buying this amp . Butbif you do . With the money you save . Spend it on better speakers . You can go cheaper with amplifiers .But not with speakers .Use the setup I have mentioned above .Out a single 8″ 10″ or 12″ in the backWith a mononamp of about 1500 or 2000 watts as well .And you’ll have a sound system for 500 dollars , that I’ll out against a 4000$ system any local audio shop charges.If you hear my advice . (In the past I was a sucker buying brand name amp everything)There’s no need . They put out power .it’s your speakers that make it sound good or not.And remember if you listen to radio Total harmonic distortion andnaol that B.S expensive Amps brag about DOES NOT MATTER!Your music input mp3’s are not studio quality . Or high definition. Your FM radio is not DVD or CD quality. Your spliting hairs buying a 700 dollar 4 channel amp .This does just fine.It puts massive power to speakers . Quite surprised how well it works actually .I went from a 2000watt more expensive amp down to this 1000 watt more simple amp . And I like this sound betterYour welcome .And sytem planning is KEY.Mine is .Two Nice components up front for highs . (Don’t cheap out) but don’t get most expensive either .Two Pioneer 8″ MIDBASS in the backseat . They make a 6 and a 1/2 as well . Their Amazing neither this amp . I bridged those .And in trunk a single 12″ with a 2000 watt mono amp . (Once again , didn’t buy an expensive mono amp . No need Just needed to put alot of electricity through a wire . Not bake me dinner )And the stereo for roughly 500$ sounds like A 4000$ stereo a local car audio shop would charge you for .Unebelivably crisp at all volumes low and high. no crackling at high volumes . It goes as loud as your ear can physically stand and more all while being clear .Inr commend the setup mentioned above. I planned it to be a cheap stereo that sound like it cost ten times more Better than any new stock radio in a Jew infinity of Lexus . Better than Bose steroes in new cars . Or beats by DRE systems.Enjoy !

    One thing to note about this amp is it gets hot and i mean hot so make sure it is well ventilated. i cant really say that i have had any issues with it this amp it has been nice for what i wave used it for. Now if you where me you make an after market cooler for this thing to keep it cooled off better seeing how it get so hot some times you cant even touch it. this amp is easy to install and can keep its own so for the price and the performance it puts out id say its a nice little amp well worth purchasing for beginners

    I got this amp to replace a broken boss 1600 watt 4ch amp, and I’m blown away! This little amp has an amazing sound to it! The highs Are crisp the mids are clear, and I can actually hear the kick drum in rock music now that I couldn’t with my other amp. Obviously this 1000watt amp is a little less powerful than my 1600 watt boss but it still most definitely gets the job done. I’ll take sound quality over small power difference’s anyday! 10/10

    At first I was a little disappointed because the gain was very low you have to level the gain until you get a buzz and then you go down two you can hear the buzz after I figured that out it’s a very good amp for the money I did a four channel on a 1995 Corvette C4 and it sounds awesome

    The one star reviews on this product are from people who either got a dud or who are too amateur to know how to install a speaker system. Is this amp cheap? Yes. Is it going to power a King Kong sound system? No. But it’s fantastic for budget builds. I have 2 6.5 speakers, 2 4 inch speakers and a 10 inch subwoofer in a clapped out Volkswagen. It’s gone into protection mode. I traced my wires and fixed the problems, and it’s come back to life every time. I had a soft top leak and this amp got wet. It wouldn’t turn on. It sat out in the sun for eight hours and came right back to life. This amp is a beast. It’s hardy, and if you get a good one it’s going to last. If you want to get a warranty and customer service with your purchase maybe look elsewhere? But if you want to shake your trunk a little and get a taste of how an amplified sound system hits, the crunch is your answer. Plus it comes with some decent stickers. Don’t push it too hard and it’ll be nothing but a good time.

    I had been having problems with my four channel amplifier in my truck caused by corrosion on the selector switches. Rather than begin a routine of disassembly – cleaning – re-assembly – repeat, I replaced it with this amplifier. Works great and solved the problem.

    The media could not be loaded.  I currently have this amp powering a homemade bluetooth stereo set, 2 75w Rockford Fosgates, and a 6 inch subwoofer.Very loud and crisp sounds! Perfect for hearing some tunes over the sounds of a production factory.

    Put this in a 2010 Mazda 3 replacing the non working bose amp, works great, the mazda has a 6 speaker but I put them into this 4 channel since the 5th and 6th speakers are dash and rear pillars works way better than the bose ever did, super clear great bass very happy with the purchase, and it fit under the seat in the original amp location with slight mod of metal plate that covers it.
