Great sub box

Sub box produces good bass easy installation using box for alpine type s 12 in 2014 maxima

Tight sound

Box is well built. Handles hard knock with no box vibration. Make sure you stuff the box with poly. Makes it sound twice as big

Great Value

This box is well built with a nice carpet finish, well worth the money!

Sounds awesome, great quality

I have 2 Pioneer TS W3003D4 12" subs in this box. I was doubting the airspace but let me tell you, if you want these subs to last, and you want to run them at a true 1200 watts RMS, do yourself a favor and get this enclosure. Any bigger and you might wreck the subwoofer suspension or motors after a bit. The subs are VERY loud in it. I didn't want to deal with the whole prefabricated ported box crap (yet) and I did not want to pay $200 for a nice custom made ported enclosure. Plus, I really hate how ported boxes only allow you to play music a few hertz around tuning frequency. I wanted clean precise bass at all frequencies. Trust me sealed boxes CAN pound, and cleanly. Only thing I would STRONGLY recommend is you dont even use the speaker terminals on the box. I have my 12 gauge subwoofer wires ran through the box via a drilled hole, and into a 2 in 1 power/ground distribution block (1 distribution block for each sub, 4 wires in from sub, 2 wires out to amp), each distribution block has two 8 gauge wires going from it to my subwoofer amp speaker inputs. If you dont want to spend more money, you can just connect some 12 gauge wires straight to your amp through a drilled hole in the box as previously mentioned.

Drill a hole in each chamber, wire the subs with 12 gauge wire to the amp and seal the hole with a hot glue gun, or expanding foam spray and silicone. Let it dry overnight.

That being said, the bass on 2 12s in this box, and my SoundQubed 1200 mono amp is very loud and hits hard. Roof flexes and windshield flexes when I want it to. But of course, if I want very musical bass, this box does it flawlessly aswell. It does it all. Deep bass, low bass that shakes everything hard, and great punchy and "kicky" bass if you like Rock or Electronic music.

Great box

This is a very good constructed box, and the "carpet" finish is flawless. The spring loaded terminals are a breeze to use, and hooked up easily using 12 gauge wire. However, the reason for only three stars on ease of use was because the cutout diameter was slightly too big for the Alpine subs I installed. But because of the power supplied to them, I left the original baffle on the box and glued and screwed a new baffle with the correct size cutouts on the box and covered it with exact fabric. Can't go wrong with a double baffle lol...great box overall.

Box called for exact cubic ft that my subs called for

Its a really well built box the only thing i would change is the connectors they need to be updated to better ones.

Well made, excellent quality

After researching many sealed enclosures, I was able to speak with Sonic Electronics technical support (spoke with Jeremy). He was very knowledgeable and assisted me in many ways. He even went as far as emailing me sound graphs that correlate to the exact box that would work best for my 12 inch subs. Box is strong and very well made. Great Customer experience as well.
