Customer Testimonial

When my factory radio died, I needed installation parts to put a CD stereo into my older Mercury vehicle. Sonic Electronix had everything I needed, which they helped me find with very friendly service! The prices were great, too!

If you are looking for good bass and still need to have space in your trunk this is what you need, the bass is strong and precised. Right now I have the gain up just a bit and I can hear clear strong bass inside my car.

I have a Saab 93 sedan and have the box in the trunk with plenty of free space to load other things when I need it.

I will recommend this over any under the seat powered based systems, I did purchase a Sound Ordnance™ B-8PT and I was really disappointed.

This box is plenty loud with tight and strong bass, off course if you want something that will shake your entire car and shatter your windows you will need something with more power, but for really good and tight bass to complement the lack of bass this is the box. Also the design is just fantantics, the box looks superb with the MTX logo.

I ended up buying this a few weeks ago, and couldnt be happier with it. Install was easy, it looks and sounds great. However, contrary to other reviews you CAN wake people up with this if its tuned in right, haha. It may be small but it can put out some serious bass for its size. I have it sitting behind the drivers seat of my van, and it rattles the whole van if i have it up that loud.



Again, this thing looks great, and sounds better. Got it hooked up with some 8g wire so its never going to run out of power.



if you are looking for some nice bass, but not to wake up everyone on the block, this is for you. It added the lows my music was missing and then some. I would not hesitate to buy another, or to recommend this to others

With proper placement for its size this things is a bass cannon that produces no standing waves that radiate throughout the vehicle.

I was a bit skepticle about going for the 8in sub, but decided to go for it anyway. And wow, I was sooo surprised with how this thing rumbles! The ported hole in the back of the tube blows so much of the bass out its amazing that all that thud comes from that little tube. For that same reason it can get a little "boomy" but with the remote bass control knob it isn't a problem if it bothers you. Since the amp is built in, the install was a breeze in my 99 honda crv. I highly recommend this to anyone who wants to complete their system without having your neighbors hate you haha.
