Fits under the seat of my Tacoma so it takes up no important space in the cab. Sounds great and adds more than enough bass to the small speakers in that truck. Install was easy as well.

After getting tired of seeing my Big Bro tossing money out the window trying to find a sub that mixes well with the factory SQ system in his Benz., I brought and installed this one for him while he was out of town. I drove his car for a week he was gone and loved it. once my brother returned home the first thing he notice was the nice clear non muddy bass he was looking for and exactly what was missing from his system. It was simple to install. I mounted in the trunk. He loved it so much he told the Benz Car Club his in about it and they all want one. So thank you NVX for making such a great product

After looking at the Focal model which literally is exact same except for a plug for VW/BMW (I have a Ford Pickup), I felt compelled to give this one a shot. Thankfully I did because I have $300 in my pocket for something else and money isn't exactly flowing for me. Anyhow, back to the product. The bass is exactly what was missing from my system. It was simple to install. I have it vertically mounted behind the seat.
It runs for a few hours a day during my commute and I haven't had one hiccup. I am really happy with the product, the service at Sonic was excellent and my trek to work is much more enjoyable.

I wasn't looking for a "hear me from 3 blocks away window shaker". I just wanted something to fill in the low end in my Excursion. Even though I have a ton of room in the cargo area, I didn't want something that I'd have to remove every time I want to use the cargo area. I chose this because of the positive reviews and the fact that it would fit under my 2nd row seats and still allow the seats to slide forward for access to the 3rd row and fold flat for cargo. It works perfectly for this application! I have to say I'm also very impressed with how low and how tight this sub is. It was a little tricky finding the sweet spot for the gain so the remote knob would work well, but once I found it, I left it alone. I cranked all the other knobs and control the crossover from the head unit. I set it so the sub handles everything below 50Hz and it does an amazing job! I'm very happy with this sub!

I would recommend it to anyone. Response is so much quicker then standard, this used in conjunction with the under bonnet chip. Really good combo. Only negative is it is really touchy and hard to drive when cold, but easy way to get around it is star the car and warm up for 5 mins then off you go. Cheers!

I just installed this sub in my 02 Tacoma and I am very impressed. The sound quality is amazing and it is much louder than I expected. Fits perfectly under the front seat, so I don't lose any storage room. Lots of good adjustments here to fine tune the sound. Excellent value. As others have stated, this is very similar to the Focal, if not the same.

After 3 months the sound getting better and better.
I install this Sub right under the storage compartment on passenger seat.
Install it on 2013 Camaro.
You don't really need big sub for your car,all you need just this Sub to full fill the missing of the bass on every car.
I have boston audio on my car,but need more bass,so i trust this sub.
So if you want good bass get this,
If you want to rattle your car don' get this.
i do have the picture on my car,i wish there is a way to upload it.

I can only say positive things about my experience with this product so far. The price is an outstanding value for the quality of the product. I did quite a bit of research and this seemed to be by far the best option for this style of subwoofer. It contains a built-in amplifier so all you need to do is hook it up to a receiver that has an RCA pre-out (any aftermarket stereo will have one, and most factory stereos too).

I had it professionally installed and haven't had one problem with the unit.

Unbelievable sound for such a compact and low priced unit. I mostly listen to rock and indie music, but I do like hip hop every once in a while and it easily exceeds my needs.

When they said this is an audiophile sub they weren't joking. My installer didn't know about these and he was impressed!!
Clean, tight bass. You can adjust bass boost, cutoff, AND subsonic levels.
Check out the pictures and then compare this to other compacts subs. I didn't think twice about getting this and it rocks!
(I have a 300zx and it fits in the footwell behind the driver's seat just right!)

I must have looked at dozens. I kept reading that most were identical, just with different brand names- but if you look at the inputs, fuses, etc, many were similar but none were identical. I stumbled onto the Focal, and dismissed it due to price. When I found this one I pulled up photos of the Focal and compared them side by side. Every screw, input, fuse, and LED location is identical. The only differences are the aluminum housing machining patterns and possibly the design of the visible surfaces of the speaker cone.

I was convinced enough that it was a Focal rebadge to take a chance. Boy am I glad I did. One of the Focal reviews said that it was not just great for being an under seat sub, but is a great subwoofer compared to other "real" subwoofers. I agree. In my small SUV this thing sounds better than the 100 watt 10" Yamaha home theater sub I purchased around the same time. I absolutely can't believe the bass it produces. It's not going to work if you're pushing 500 watts to your mids, but if you're looking to add bass to a factory system, or aftermarket head unit, this is your sub.

Mount it close to you, have crossover control over the other speakers, have an equalizer, and have a quiet/dynamat car. Even if you have none of these you can get good results from this sub.

At 8" you aren't going to generate a lot of SPL especially if its in the trunk, it will sound like you upgraded your 5" round to 6x9s. Mine is in my hatch hidden behind a panel and it fills in perfectly but it leaves me wanting a bigger sub . I'm not willing to give up the space, so this is perfect for now.

Without crossover control over the other speakers the bass can sound a bit muddy and with a equalizer you can really fill in the mids and highs and get great results from this sub addition.

Bottom line is this is the best looking compact sub on the market with its cnc and anodized look, the blue led on the crossovers and gain knobs is a nice touch. Took one star away from durability because mine arrived WTO (won't turn off).

I needed bass in my Jeep Cherokee and that is what I received when I had the guys at Sonic Electronix install the QBUS8. It perfectly matched my deck and coax speakers giving me a full sounding vehicle. It is really small so it does not take up any space but you can hear and feel the bass. It enhances my sound system without a huge amp or woofer that will take up valuable cargo space.
