Teeth Rattler

It's big. If you have the space in your trunk and not a ton of money, buy this. I just measured this package and it hits real hard around 30-40hz. I highly recommend it if you're on a budget and want huge bass. Especially considering the amp is also included. Awesome package. Keep it up, NVX.

I have to give it to Sonic as well. This shipped faster than Amazon and they kept me updated along the way.

Great “Bang” for the buck!!!

I got this for my son’s 2007 Cobalt. First off it’s a beautiful well made box with sleek/classy looking subs and the logo embroidered on top was a nice touch. The box is a bit on the large side, we had to remove rear seat and backs and go in the trunk that way to get it to fit but no biggie. The amp was simple, classy and fairly compact. Runs cool and pushes the subs perfectly. This system absolutely slams when you get it tuned up right!!! Definitely hits hard for a 500 watt system.

Awesome Price to Performance

I recently installed these in a 03 pontiac vibe matched with door speakers and tweeters. Tuned at 50hz -5db with a kicker test tone. This package performs very well for the size of the vehicle offering enough true low end bass at a fraction of the cost. My one complaint remains in the fit and finish. around the left side of the port as soon as she started receiving signal the carpet began to flay itself off the box. Picked up some Titebond III to resolve the issue. Amp stays nice and cool and was straight forward to wire. its more compact then expected saving me room to top mount both amps. overall id give it a 4 out of 5. if your not an audiophile this is a great beginner option offering true mid range quality when paired with a full system. :)

Nice set of subs with the box.

Easy way to add quick good sounding bass. Won't blow your ears off but sounds really good.

Great value

Highly recommend for anyone wanting a good sounding system for a budget. Easy installation paired with an NVX LOC, and the NVX amp wiring kit. I was surprised with how clean the system sounds, beats harder than my base kenwood system in my old car. Very impressed with all of the NVX products. getting the enclosed duel 12s and the amp, for this price this deal is unmatched by any. Best value on the market.
