The port makes all the difference!

I swapped out an SSL 8 inch powered sub for this ported NVX sub in my wife's Outlander. I have it positioned under the front passenger seat, with an RCA adapter to the factory headunit. Holy smokes, this sub blew the old sub out of the water! Obviously this thing isn't meant to shake mirrors, but the lows are much more pronounced, thankfully without any port noise. I've been running it for a couple weeks now and it started to really come alive a couple days after install. Very happy with this sub!

Better than the 8" competition sub in a full enclosure with a 900W amp

I had a classic VW convertible with an 8" competition sub on the rear package tray but with the top down you couldn't really get much bass out of it. Figured I would try this under the seat sub and was very surprised! I removed the sub on the package tray and will use just this one for my build. Very happy with it.

Not bad for limited spaces

Does a decent job for a small subwoofer. Not going to win any competitions buy definitely enough bass for me. I would recommend for anyone that does not have a lot of space for a subwoofer.

Lounder then you think! Great value!

Easy to install and set up. Installed in a jeep patriot. Definitely louder then you think it would be. Adds just the right amount of bass at a great value. Feels well built and durable, everything it well protected. Would 100% recommend if your just wanting that little extra bass with your music with out breaking the bank.

This thing rocks

Purchased this NVX under seat powered enclosed 8" subwoofer, for one of my 1st Gen regular cab Tacoma pickups, because of the lack of cab space.
After installing this NVX unit, I was blown away at how awesome it sounds. It really brings the bass to my music, and in a small amount of space.
I definitely recommend this NVX enclosed powered subwoofer.
I highly recommend this product.
High quality, awesome sound ,and great price. Thanks you guys at Sonic Electronix !!
