Size: 1000W RMS Monoblock
Earlier this year, I had a shop install an old amp of mine and a pair of subwoofers in my dad's car for Father's Day - and later in the year, I borrowed the car to take my brother and his kids to the airport (about a 6 hour round trip) - well, the 5 channel amplifier didn't like the heat, or the amount of strain I put it through, and it cooked the sub channel. I ended up replacing it with a Hertz 4 channel amp for the door speakers, and this amp for the subs. This isn't one of those "thousand watt" amps that's fused at 30A, this one's fused to a total of 100A, so it very likely delivers the power it claims. I wired the subs to 2 ohms, so only 660w according to the manual, but those subs can still pound at that power level. If you buy this amp though, be aware that it has air venting on the underneath, for cooling - be prepared to mount it with some breathing room.

I blew my old amp after many years of use and it had a lot of different channel settings and was perfect for my 2 subs, after running this 2ohm box on the 4ohm bridge (1 and 2) I can tell something doesn't sound right. The highs seem to hit harder but my subs aren't hitting lows or subsonic very well. I'm hoping this amp didn't blow my subs because I'm also noticing a slightly different rattle from my car than with the old amp. It sounds like it's coming from the trunk but obviously with rattles it's hard to isolate. I'm hoping I'm not going to have to replace my subs because of this amp. No matter how many different EQ settings I try to pump into it I can't seem to hit the subsonic notes. The amp itself just doesn't have enough dials to control the various aspects of the audio like my old amp did. The amp works, it looks pretty nice and for the 200$ price tag I suppose it does what it says it will do, but I'm really not happy with the quality of sound that I'm getting from the amp. I'll probably keep it and play around with it some more but may end up returning it and trying out a different amp. I haven't gotten the chance to really dig into my subs to see if one of the cones blew out or if something got detached. I pushed my subs pretty hard after installing this amp, probably harder than I should have, but that's mostly because I wasn't getting the sound I was looking for from the amp, also the amp runs hot, I don't have a mount for it and it didn't come with spacers for me, I noticed some reviews said it comes with spacers but mine did not, right now I just have the amp sitting in my trunk with the fan face down but with how hot it gets I'm worried it's going to pop into protect mode unless I find a spot to mount it in my trunk with a bracket, so that's on the to-do list for me, the amp looks nice and the quality of material seems decent enough, it's heavy and feels sturdy, the instructions aren't very clear on the potentiometers though and whether or not the channel 5 potentiometers impact the sounds on channels 1 and 2. Also worth noting is the amp didn't arrive with the wired remote. It isn't a huge deal but I reached out to the seller to see if they can send the remote. *edit I tried hooking the subs up to channel 5 with 2 ohm resistance but there was no output for the sub channel so I hooked it back up in series to the channel 1 and 2 bridge with 4 ohms. I then proceeded to adjust the potentiometers for channel 5 which I believe adjusted the sound coming from the subs. It's late at night so I didn't have the chance to test it but it sounded a little better at least while quiet. I'll do another update in the morning and increase stars if the subsonic frequency increases and the amp allows the subs to hit the tones I'm looking for. Crossing my fingers and hoping it works.

This is a very large amplifier. Almost 20 in long, over 7 in wide, and 2.4 in tall. It's rated 135 watts per channel at 4 ohms. It does just a little bit less than that, about 120 watts per channel. You can go on YouTube, look up HiFi Vega, and he does a dyno with this exact amplifier, and a sound listening test. I'm more about sound quality than I am being loud. That being said I feel the amp sounds pretty good. Right now I'm running it in a three-way setup, running the front speakers on the front channels, and running two subs on the back channels. It's really not enough power for the subs, but for the moment it works. I plan on getting a dedicated monoblock for the subwoofer. I also made some blocks to lift the amp up. Having the fan on the bottom, there's not a lot of space between the amp and the floor. So I cut up some strips of plywood, about an inch and a half thick, carpeted them, and then screwed them to the bottom of the amp. Now the amp is off the floor about 1 and 1/2 in. That way it has a little bit of air flow now. You do want to make sure it's in a well ventilated area, because the amp does get warm, it is a class A/B amplifier. Class a b amplifiers are less efficient than class d. But they sound better than class d. When you're running your power wire you want to make sure you're running at least four gauge. You do not want to run anything smaller than that. And if you're running this amp along with another, then you definitely want to run zero gauge. So far, I've had no issues, the amp sounds great, puts out plenty of power.

It's a workhorse of an amp. It's underrated power wise for sure. The only issues I have is that the bass knob could be better built but it is accurate. The fan is on the bottom plate so if you don't elevate it high enough for it to breathe when you mount the amp it will heat up. I can't count that against NVX because that's more of a user error.

Good 3 channel amp for small system. The 3 crossovers are nice to clear up distortion and separate frequencies. The single amp makes for a clean install. It does runs hot and needs a lot of air space.
