VIBE Optisound 8″ Underseat active bass enclosure, Black, OPTISOUNDAUTO8A-V2

 

Cant fault it really. Was worried it would not have much affect as people say its nothing like a big sub but i beg to differ. Its much closer to having a big sub than it is to having nothing. Comes with everything needed to fit all wires and brackets to screw it in. Has gain adjustment but no others.

 

if for some reason you also own a Suzuki swift 2010-2017 3 door then be assured this subwoofer will fit EXACTLY underneath the seat without sticking out nearly at all, while the volume knob is also hilariously reachable when driving to suprise your passengers.

 

Build quality fantastic, sound quality is excellent..however not sure this could be classed as an underseat sub unless its for a van, it is massive compared to other underseat options and wont go under the seat of any of the 3 cars in our household.
Its more what I would call a space saver sub as its fairly slimline but width and depth wouldn’t allow it to fit neatly under most seats, plenty powerful and a nice plug and play option with simple install, just be aware of the size if you are planning to fit it in a tight space..unfortunately I had to return it for these reasons which was a shame as I really thought it was a fantastic bit of ki

 

Originally bought this from Halfords.
I have fit this sub in two different vehicles:
A Toyota MR2 MK2 Rev 5
and A Nissan Skyline R33 GT-R.

The sub is actually slightly too tall for the MR2’s seat so I put it behind the seat using velcro to mount on the wall.
The bass produced from this is notable and adds to current speaker setup but not powerful / deep by all means. It is easily outperformed by any proper sized boxed 8″/10″/12″ enclosure. Gain was set on max and no adjustments made to Headunit.
This sub was later replaced by 2x ported box 8″ Sony Xplod setup in the MR2.
At this point I found the sub to be underwhelming and would have rated it no more than 3 stars.

3 years later. I added this to my Nissan Skyline as a temporarily subwoofer to add to the music quality.
Again gain was set to max.
At first I thought it was too weak to even produce any real improvement. I later turned the audio up and heard the bass but it was quiet. So I turned the subwoofer up 13/15 on the head unit adjustment and all of a sudden I can hear the lows and a decent level of bass in the car. I was completely shocked by how well the sound was produced from this compact Vibe sub! There is minimal distortion as well to my surprise. It doesn’t deliver any kicks being in the boot but the tone reaches the front of the car like how most small boxed subs would.
Not to mention it does reach a decent level of low frequencies. However, if you have an aftermarket exhaust, ensure you have sound deadening at minimum otherwise the exhaust will cancel out some of the low tones.

I would definitely recommend this if all you’re looking for is audio enrichment without any space loss.
I cannot comment on its performance from Under the seat because it does not fit under both car’s factory seats. as there is not enough clearance.
