    • Great value, my third NVX AMP that doesn’t disappoint
Size: 1700W Monoblock
These amps are amazing. No frills packaging just clean power. They tend to exceed the quoted RMS when tested. Truly delivering CFA rated power. They also seems to package the electronics smaller than the competitors. The highs: Bass knob Very adjustable crossover frequency Room for large gauge wires Small form factor for the power. 1ohm stable ... show more

    • It's a speaker cooker!
Size: 440W Compact 2-Channel
Review Image by Tommy Gun Tommy Gun
The 440W 2ch Class D Sounds great and the reverse polarity protection works. Make sure your speakers can handle the power. I didn't and ended up smoking the 6.5in component speakers on FLHX while out on a ride. The amp does get pretty warm. I added a small fan in the fairing to help with air circulation. I got new speakers that can handle more power but can only turn it up half way. Even at half volume it's an impressive improvement over stock. ... show more

    • Top Shelf Amp, Lower Price Point, My Harley is Happy
Size: 440W Compact 2-Channel
This amp really woke up the Kenwood 5 3/4" speakers I had in the fairing of my street glide. I thought they were crappy speakers, so I bought this amp with some Diamond Audio speakers to get my sounds right. It sounded good with the old speakers (tested with them so as not to risk hurting the new and expensive ones). It sounds GREAT with the DA 6.5"s. I am only using 30% gain. This could run four more speakers if desired. Fit perfect on a bracket I made right above the radio. Really looks like DA's amp and it would not surprise me if it was the same unit for half the cash. Really happy with this badboy! ... show more

    • Value 5 channel with good sound
Size: 1100W 5-Channel
Good Value 5 channel that I installed in my 2014 Jeep Wrangler. Front and Rear sound amazing, cross overs and controls all work very well and produce a great sound balance. Cons - 1 star sound quality / Sub channel @ 2 ohms is lack luster. I didnt expect the same pucnh as a but for an advertised 600w at 2ohm load it is out paced by a mono 400 it replaced. - 2 stars ease of install / Speaker outputs are angled down and have pointed screw contacts. I found with the amp control wire, and anything under 16g is cut off in the clamp and screwed tight. I ended up sodering my ends to ensure that they were not cut off. These angled contacts are almost impossiable to get to once installed as well, so make sure you have plenty of space before mounting to make adjustments or connections. All in all though, even with the shallenges of connections and lower output sub channel I am satisfed with the AMP itself. Clear and clean sound, minimal to no altenator whine, and no shart snap to the speakers on startup or shut down. ... show more

    • Amazing!
Size: 400W Compact 4-Channel
Works great on my 2018 roadglide, very easy to install and fits perfect under the head unit! Amp has plenty of power to handle the two front and I’m sure it has plenty enough power to handle bag speakers if you want. Only have gain up 1/8 of the way and it jams out!

    • Great but hard to connect multiple subs
Size: 1000W Monoblock
Needs multiple outputs or larger holes for hooking up more than 1 sub.

    • It the best
Size: 400W Compact 4-Channel
The price isn’t bad but I guess I would spend more for a nicer amp. I replaced a JL Audio 400w 4 channel amp and the quality was substantially worse with the NVX. I have to turn the gain way up to get it loud enough but it is not very clear. Ultimately I am going to get a different amp. I have it connected to 4 5” JL Audio speakers. It Just doesn’t perform well enough ... 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
