5 out of 5

I've had this installed in my Focus ST for a couple of months now and couldn't be more pleased. Paired with the JL Audio XD300, Excellon XR600-6DSP, iDatalink Maestro AR, everything sounds the way it should have from the factory. It hits harder and louder than many 12"s I had in the last 20 years.

Awesome sound, nice fit, terrible mounting method

So clean and tight bass... puts all my other previous systems to shame. Expensive but worth it. Driven by a JL 300w amp. Blown away. Love it. Only painful part was installation. I had to take the body cladding apart then drill a big hole through my car body into the wheel well. Good God, what engineer thought that was a good idea? There are body posts in the area, why ask people to drill huge holes in their cars? Lastly, the speaker wire inputs are in the rear, so if you need access, you have to unbolt everything. Dumb. Can't give it 5 stars as its so bad.

The Best Option Money Can Get

Perfect fit and amazing performance. I powered it with a 5 channel amp which outputs 300 watts at 2 ohms and it meshed perfectly. I couldn't ask for anything more since it retained about all of my trunk space and added some much needed lower frequency punch.

Amazing Sounding Sub, Terrible Mounting Flaw...

Okay, first things first, build quality and packing of this Stealthbox is top notch. Just like the other 2 JL Stealthboxes I've purchased in the past, this one for the Ford Focus hatchback didn't disappoint in that regard. The carpeting quality and color used was near an exact match of the factory interior. So why am I only giving this product 3 stars? First, the "brand new" box I received directly from JL Audio shipped with a bad speaker. Secondly, the mounting solution has such a glaringly obvious design flaw, whoever designed it should be slapped silly in the face. I'll address the mounting flaw first. This Stleathbox requires drilling a 1/2" hole through the passenger side fender well. Which is fine, that's not a big deal. You then have to mount a "threaded bolt" through that 1/2" hole. The Stealthbox slides over that thread bolt and then you bolt the box to the fender well. The problem is, JL Audio installs a "threaded" insert on the Steathbox! It's impossible to thread the box onto that bolt. I actually had to drill out the threaded insert, which was a complete pain. Second flaw, was my brand new box actually shipped with a bad speaker. I paired my sub with a JL Audio XD300/1. After much trouble shooting I narrowed the problem down to a bad speaker. Crutchfield shipped a brand new one, I got that hooked up and the box sounds absolutely amazing in this small car. If I didn't run into those problems, this sub would easily have been 5 stars.

BASE ST ADD IN

This sounds great. Enclosure seems very well built. I Havent bought new technology subs since about 2001 and Im impressed. Im using a Precision power I450 with it with the gain at about 60% w/ the remote. I was worried about the shallow mount (my 1st) producing, but this is as loud (but clearer) than the audiobahn 12 in a ported box that had in my last car. Put it in at work (car dealership service) and alot of people came over to hear it and were really inpressed too. I can actually feel the spl pressure if I turn it up
