## Customer Reviews

### ⭐⭐⭐⭐⭐ Read, think, buy.
*by B***N on October 18, 2013*

An amplifier's quality is defined by it's ability to efficiently and accurately reproduce it's input signal at a higher amplitude. Period. This amp is good.Without having metered the outputs under load, I couldn't tell you it's true RMS. What I can tell you is that this amp produces loads of clean power and is worth several times more than it costs. Any $500-$600 amp can deliver this kind of power, but likely wouldn't have as many usable features. I prefer audiophile grade gear for my own car, but this was a gift for my girlfriend and now her Civic dumps (1x RF P312D4 large slot-ported). I had to back the input sensitivity off considerably because her mids are still deck-powered (Eclipse) and she couldn't hear the lyrics. I didn't use the bass knob because it's ugly and the deck I gave her has adjustable sub control.The 4000 watt power rating is a joke, but it's the price that I'm laughing at. $125 doesn't buy much off the A-list.The multi-amplifier bridging capability is pretty rare, and much appreciated. The cable is even included. Unheard of.The power and speaker terminals accept forks, and are spaced plenty far apart. Whatever power cables you have WILL FIT.It's solid. The features are excellent. Buy two.MECP Master #CEA212201 (2013)

### ⭐⭐⭐⭐⭐ 2 months in and still rockin'
*by I***1 on September 19, 2013*

I didn't think I was getting a good quality amp, I just thought I was getting a good priced amp. Well, after a couple of months pushing this thing hard, I've got no complaints. I'm pushing two Kenwood KFC-W3013PS 4 ohm 12" subs in a sealed box. They are rated for 400 watt RMS and 1200 max. These things have almost 3" excursion and are close to blowing my windshield out at HALF power, no bass boost, sub level on 1, and the gain at 1/4. I'm scared to turn it up any higher and my Excelon mids and highs won't keep up anyway. I even went cheap on the wire, 8 gauge. Don't even notice lights dimming unless I crank the volume to 30 on my kenwood Excelon deck. I drive over an hour each way to work every day, never had any overheating problems and believe me, sometimes I jam the whole way home. I listen to everything from metal to dubstep to country. It all comes in clear and hard hitting with this affordable amp. Thanks AMAZON

### ⭐⭐⭐⭐⭐ Quality built powerhouse
*by 3***Z on April 12, 2013*

I choose this 4000watt version mostly because it is 15"X10" & fits in the Nissan 350z glove compartment with about an inch and a half of space on each side, and about 6 inches in the rear of the amp. I am using the KnuKonceptz Kolossus OFC 4guage wire kit, and no capacitor. I am using a 120AMP ANL fuse supplied with the wiring kit, the amp itself has 3, 40amp fuses. I have yet to do the big three upgrade and I still get absolutely no dimming in my headlights, LED dash/undercar lights, or map lights!!!I used a Targus AWE45US HeatDefense gel laptop cooling pad for under the amp. It is made of crystals that when heated up turn into liquid, dissipating the heat. At the moment this amp does not even get warm to the touch, it literally stays at the cars interior temperature, even after hours of use. I have this amp pushing a 10" 4ohm, single voice coil, 300-1100watt Subwoofer in the 350z touring edition's stock Bose sub location. I used spray foam and dynamat to seal it into a 12"X12"X16" enclosure that only weighs about 3 pounds =). I have it turned up to 50% gain, and about 10% bass boost, the crossover is set as high as it goes (150hz) This amp slams so hard I barely half to turn my pioneer avhx2500bt head unit to half volume. I could still easily hear and could still faintly feel the punch from about 100 feet away. I plan on upgrading to a 10" pioneer premier series DVC (2 ohm) 3000watt sub.The RMS rating on this amp are very true to what this amp is pushing, if anyone tries to tell you otherwise, either they got a defect, they have a cheap CCA (copper clad aluminum) wiring kit, or they don't know how to wire an amp. A CCA wiring kit would have to be 3 times bigger than a OFC (oxygen free copper) kit, to push the same juice. So you would need a double 0 wire (-1/0) CCA wire to equal the 4 gauge OFC. The shorter the power cables the smaller it can be. The shorter the grounds the better.RMS Ratings are as followed:1500watts RMS at 4 ohms2000watts RMS at 2 ohms2800watts RMS at 1ohm / 4000watt peak.
