This sub fits the bill just right, its compact enough to fit under passenger seat. The unit has plenty of adjustments available to get the right balance needed for a superb sound. I never liked overpowering bass, and most certainly not the distorted bass you hear in most installations. After "proper" adjustments were made it was truly a pleasure to listen to the radio.
Installation was easy enough and including hiding all wiring from view it took about 2 hours to finish it. After spending a week fine tuning it to my liking, balancing the sound of the radio and subwoofer, I can say it fits the bill nicely.
It’s a very well built unit and should last a long time, hopefully.
