For the price, it's a great little powered sub. Well worth the money. In my second vehicle, Nissan Frontier, with replacement speakers and a mini Clarion amp powering the speakers. I have a huge system in my Mustang but don't want or need all that in my truck. This is just a system that sounds much, much better than factory but not crazy. The sub is great for filling in lows. It's not crazy bass but still noticeable and surprisingly loud for what it is. Left me all my storage space in the cab. Good choice for classic rock. Can do hip hop but breaks up a bit with low bass or too high volume. Fills in the bass and complements my system but doesn't overpower i it.
1. Price, obviously. I love the Kicker brand but I could but 2.5 if these for one Kicker, Alpine, Focal, etc.
2. Even though it's less expensive than the bigger name brands, the quality is still there. Nice metal casing. Included bass knob. 100 RMS where others are often less.
3. Speaker level inputs and auto sensing turn on made it very easy to hook up to my factory receiver.
4. Fits perfect under the seat and would do well on the back of a cab on smaller pickups.
5. Class D amp runs relatively cool making placement easier.
6. Fully adjustable subsonic filter, crossovers, bass boost, phase. So nice to have the control. Especially the subsonic filter. Most other similar products don't have one or have a fixed subsonic filter that's either too high and cuts out too much bass or too low to be effective.
7. Accepts bare wire power connections. Easier.
Cons (nitpicking really but good things to know)
1. Claims frequency response down to 20 Hz but I don't believe that. I didn't expect it either but just keep in mind it won't go as low as bigger subs. For it's class (small powered sub) it still does well.
2. All wires are on the same side. Kind of a pro and con. Makes installing easier but the power cables so close to the speaker cables can easily introduce noise. Thankfully I have no hum!
3. Only way to mount is included screws and mounting holes. Not ideal as most floorboards aren't flat. I used zip ties in the holes and wrapped them where they didn't interfere with anything.
4. Not a volume champ. It's a "round out the system" type sub and not a thumper. High demands can distort it. If you need boom, this isn't it. I didn't and it's perfect for what I wanted.
In the right system setup and with reasonable expectations, this is a great piece of equipment. I have it on my factory receiver, gain at @6/10, subsonic filter at @30 Hz to keep our bass that it CAN play but just not loudly before breaking up, crossover at 120 Hz, bass boost at half, and bass knob at half. This is perfect as it allows me to still use the knob to turn it up when I want a bit more without distorting. I don't recommend turning the bass boost all the way up. That little 8" does well with a bit of bass boost but too much and sound quality suffers. This is starting to sound negative but I am very happy with the unit! Just keep it in it's comfort zone and it'll do great filling in the missing bass.
DO NOT just turn the sensitivity and bass boost all the way up!!! I did my initial setup and did just that out of curiosity. A ton of noise, distorted bass, and the small sub couldn't handle all that signal and bass boost. Use a light hand on the bass boost!
4.5/5 or 90/100 overall. Almost as good as it gets for the $$$. If it could just play a bit deeper it would be perfect. Still, I doubt there's a better powered sub for the $$$ out there. I'd never bought NVX before (Kicker, Polk, and Rockford only) but just wanted a small system in my truck that didn't break the bank. The reviews convinced me. NVX seems to be the real deal and a decent brand.
