Review
Installed these kickin' woofers as my friend had recommended me to get them. Had a preview of it on his car, and I was blown away by it. They were slightly expensive for my liking, but after getting the 'sneak peak' of it on my friend's ride, I had definitely love them. Now, after 6 months of using it, I find that it was definitely worth every cent. It produces a crystal clear tone, along with excellent low toned bass with maximum pounding. It doesn't feel 'weak' as compared to some others which after some time, the vibrations and pounds coming from the woofers get weaker. Mid and high tones are delivered well, and I must say I have enjoyed these 6 months having this woofer installed in my ride.

What I like
Excellent low toned bass that pounds, along with great sounding mid and high tone delivery.

What I do not like
Expensive for any average driver's liking.

Review
This sub is GREAT! I figured it would be since MTX has a good reputation, and the reviews were great as well. I put this sub under the middle of the front seat. It sounds spectacular, blowing me away. Tight crisp bass when I dial that in, and the boomy chest thumping bass when I dialed that in. I highly recommend you find the remote control knob and hook it up too. It gets plenty loud for what I need it to do, but I won't win any contests with this single sub. It does provide the perfect level of low end punch and boom I was looking for.

What I like
What it has to provide is really awesome. Just hear a sample of it, it'll be enough to make you go mad for it.

What I do not like
The price..
