Holy crap this thing sounds great!.
It was a little longer than I was expecting but still installed fine under the seat.
The 12v, remote, and ground connections are PRO. Much better than the run of the mill amp screw terminals with metal exposed.
These are screw type, with individual holes for the wires, no exposed metal or wire… nice a clean looking
It comes with a wired remote to control volume but you do not need to use it. If you leave it unplugged it sets the sub to max and then you can control the sub level with your headunit’s sub control.
The blue led light on the unit was a little distracting to me, but there is an on/off switch for it on the unit.
I didn’t mess with any of the gain / crossover settings, just plugged it in and went to town.
It sounds great. It isn’t overpowering the other speakers and it isn’t rattling the windows. It adds enough punch to the sound to be perfect to me.
In my car it is paired with 4x Polk db651s and it sounds exceptional. Zero distortion, clean bass. The very low freqs sound a little faint but I think that is expected because of the compact size,.
Overall I a very pleased with this and I highly recommend it to complement a good mid bass / tweeter setup.
