  • FEEL THE POWER!
Style: 600W Compact 2-Channel
Finally got a small footprint amp for my DIY ammo can speaker build. I am using it "full range". Install and connections were a breeze. The input sensitivity pot was turned down out of the box...had to turn it up. No big deal. THE GOOD: - Powerful-powerful-powerful (150w RMS x 2 @ 4 ohms) is an understatement. - Clean. I was worried about Class D amplification sounding choppy or weak...this amp is pure butter - Small. Perfect for ammo can builds or where space is limited - Efficient power and power consumption...won't bleed your battery down BOTTOM LINE: I have 40+ years working with amps and speakers and have a "critical ear". This amplifier is a beast of power, clean sounding, and does the job vs amplifier costing 3x as much (and larger Class A/B amps). You'll be surprised how powerful it is and what it can do. UPDATE (23 Sept 2020) - It does run very warm if left on all the time. "Hot" if you are thumping high volume levels. You might consider mounting this amp with good air ventilation and on a surface that won't be impacted by the heat. Still 5/5 stars...it hasn't let me down UPDATE (11 May 2021) - Bought a second one and bridged two of these amps in one of my ammo can builds. TWICE THE POWER! So, now I am running well over 300 watts (RMS) @ 4 ohms. These amps are beasts of power. Get this...using a standard 30-amp fuse and 10 AWG power cables. zero issues. These amps sound great. Again, I thought Class D amps would not produce clean sound, I was wrong ... show more

  • Great quality period
Style: 1700W Monoblock
Very surprised for the size, and the cost, its pushing 2 nvx 8in dual 2ohm 650rms in the skar under seat box for a 2013 ford f150 crew, and its slams. The bass is low and flexing windows and clean. Been running hard now for almost a year.

  • Excellent Sound And Performance
Style: 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
