    • Excellent Sound And Performance
Size: 1100W 5-Channel
It's been a week since I installed the NVX VDA 11005, and I have found myself wanting to sneak away to my car for a listening session just to appreciate and absorb the improved sound fidelity over my previous amp. The NVX replaced a failing Pioneer 5 channel amp that had slowly been reduced to two channels over the past 5 years. It's the second popular name brand amp that has failed me in the last ten years, so I decided to try this amp and see what happens. I obviously cannot speak to longevity yet, but the improved sound quality...man...it's noticeable. Installation was a breeze as I already had everything in place. It has a slightly smaller footprint than the Pioneer which is nice. Wiring was straight forward and easy. The only catch is that the power and ground inputs have a little trouble accepting my 4 gauge wire which was a bit surprising. It's not as clean as I would like, and I'll probably revisit it soon. Tuning was surprisingly quick relative to my previous amps. I was able to get the sound right in the pocket without much fiddling with gain and filters. The subsonic filter may have something to do with the quality of sound. Neither of my previous amps had this feature and I suspect that my 12" subwoofer was having to work harder than it should have, trying to produce sound that it isn't capable of handling. The result is a cleaner, warmer, and thumpier base that is less directional and more consuming. It's less a shower and more a bath of sound now. I have 6.5" components up front, coax in the rear deck and of course the 12" sub in the trunk. There's plenty of power to each channel, and really, the stock satellite speaker wiring is probably limiting me at this point. The sub is a 4 ohm DVC wired in parallel to run at 2 ohm which the 5th channel gladly supports. The remote bass boost knob let's me push the sub as hard as I want to but I don't care to know the limit or come close to it. It's plenty of power for my liking. Btw, I would recommend using a capacitor to ease the power draw on your battery. Overall this is a fantastic amp for the money and is a huge win for NVX, which is a Sonic Electronics in house brand from what I understand. Nice. ... show more

    • ABSOLUTELY THE BEST VALUE FOR YOUR MONEY
Size: 1100W 5-Channel
I only started using NVX products in the last year, but let me tell you, their amps are absolutely the best value for your money. I own the NVX VAD1700.1, VAD1100.5, and the VAD1000.4 and they have all performed beyond expectation. The sound quality is amazing and the power is a true rated RMS. Several of the NVX amps have been dyno tested on Youtube if you need proof of their ratings claims. The amp does get warm, but that has not translated into any complications or issues for me as I can run my system at 3/4 volume for an extended time and the amp has never shut off or gone into protect, which is true of all of the NVX amps I own. I would recommend mounting it with spacers, like 1/4 inch thick rubber feet pads to create some extra air flow space under the amp, but that's a personal preference thing for me as I have always done that. These amps are also very compact for the amount of RMS power they put out and can easily be installed in locations such as under a seat or behind a trim panel with no modification. The other thing to know about these NVX amps is that they utilize a SUM OUTPUT. This means that you must have the left AND the right RCA going into the sub woofer channel RCA inputs of the amp from the head unit. If your head unit only has one sub RCA pre-out or if you are splitting the left rear channel RCA for your sub, you will want to make sure that you connect a "Y" adapter at the end going into the amp. If you fail to do this, you will only get half the volume or less from the amp. I have found this to be true for all NVX mono and five channel amps. You can't buy a better quality true RMS amp than these NVX VAD models for your money. If you're on the fence, get off of it and pull the trigger. You won't be disappointed. ... show more

    • The most versatile cost effective amp ever
Size: 1000W Monoblock
So small. So powerful. So perfect. This Monoblock rates 1130 watts on the dyno. Hasn’t gotten hot once. Barely warm to the touch. I have it pushing 2 CTSounds 8’s. People think they’re 12’s all the time. Mean little amp. It’s NVX for me all day over JL, RF, and the likes. You just can’t beat the price. Doesn’t draw power and make your headlights dim either. ... show more

This amplifier is awesome and the price for it amazing. Installed it in my 2022 HD Road Glide setting the input to 5v while using a speaker level to input level converter till I could flash the GTS radio and fully set the input voltage and crossover. Once I flashed the GTS radio to a flatter EQ and lower output voltage I set the input voltage on the amp with radio playing a 1khz signal at full volume using a Oscilliscope to find when it clipped and backing off to a clean signal. Scope shows that at 28.1v which with a 4ohm speaker would be 197 watts, impressive! In the garage all tuned the speakers are clean and ear bleedingly loud. Have Polk 652 speakers installed and this amp woke them up big time! Highly recomend this awesome little class D amplifier from NVX! ... show more
