Heavy Duty!
I would recommend this product for the guy's out there that are serious about their music. If you got good, high quality subs, then this box will make them perform to your sub's max output with out worry of blowing up your box.

good value
product worked for my new hifonics subs. that will be a winter system for my ride so i don't have to keep my main subs in all year round. i really like it mostly because its has black carpeting.

The Box that Rocks
Appears to be fairly well built. Arrived with a little dent and a tear but its too little to bother with. Sounds nice but doesn't hit as deep as I would have liked. Small size however, leaves me some room for a couple of bags of groceries. Three stars for durability since I've only owned this for about a month.

Amazing Enclosure, Even Better Price.
Ordered this as my first enclosure, put two 12" subs in it and I haven't found a box that hits as hard and as clean as this one has. Will definitely buy from SonicElectronix again for my car audio needs.

Fast and easy great buy
I got my complete set up: 12" kicker subs box 1000watt Mbquart amp and amp kit. I have always installed my own equipment, I found it helpful that they have videos that covered some of the product they carry. There are a few shop's in Texas like Best buy and Custom Sounds that offer equipment. But the professionalism of the knowledgeable staff the price and the reliability made it clear that I wanted to do business with them.

Cant beat the price. But it is really very good box. I put two 12" hifonic,also bought from here, with a 2 channel 1000 watt amp.It really shook my rearview mirror in my '97 towncar. My brother loved it so we put it in his '92 prelude.Wow!!! You can hear him before you see him. Great buy!!!
