Is the best choice for an active subwoofer if you do not like the ugly boxes in the trunk. - Super sound - is in the bass pressure of boxes in every way. I've even gained a puncture repair kit and everything is neat and tidy. - The trunk remains fully usable. The bass is so high turn up that the seats and hum all loose trim parts rattle, just as it is considered not in the long run from. So enough room for improvement. I had bass bins "indicated" 1700Watt ranging not ran at this. - Best processing - Easy Installation - Tailored (internal amplifier - subwoofer)
I can advise only to this purchase - about 5 star !!!
