Good quality

Im really impressed with this subwoofer really balances out my 6.5 midbass speakers and 6x8 speakers it hits really hard it definitely can overpower the speakers so far skar audio has really impressed me (minus me not receiving some reward points from previous purchases) my whole system is skar audio speakers and amps in my superduty definitely wish skar made a version of this in a 12 or 10 id definitely buy a few if they did

Just the thump I needed

If you're looking for big bass, this ain't for you. If on the other hand, you're looking to add some punch to your ride without sacrificing any usable space, this is just the ticket. Small enough to fit under a front seat, or in my case, mounted behind the back seats of a Ford F-150 Super Crew, this compact unit adds a respectable thump and picks up where the aftermarket stock-replacement speakers leave off.
Beware: the sound is so good that it will leave you wanting more, but if you're unwilling to sacrifice the space, it's the best you can ask for.

Sound excellent
Installation 📦

I installed it on a 2017 Honda Civic, and I really liked its sound, it makes the factory sound complete

Very nice

Easy way to spruce up your system. Not window rattling bass but adds a full range sound most systems are missing.
