Product Description

It is a known fact that in order to create a 50% increase in your sub bass system you would need to double the power. For example, if you are hitting 135 dB's with an amp that produces 500 watts of RMS power, in order to hit 138 dB's (50% louder) you would need 1000 watts of RMS power. Taking it one step further, to double your dB''s (increase of 6 dB) you would need an additional 2000 watts of RMS power. However, if you are looking to add bass to your car audio system, but don't have the money to buy a new amp, you might want to consider upgrading your speaker box instead. Now you may be asking yourself how a simple subwoofer enclosure is going to achieve the same results as adding massive amounts of power? The short answer is by cutting a port hole in your sealed enclosure. With a sealed sub box you are hearing only half of what your subwoofer is producing. However, when you make access to the back side of your woofer via a port hole, the sound can increase up to double compared to designs where the woofer's back side is sealed off. There is no greater example of this than the "Labyrinth Power Port" that Obcon Sub Bass incorporates into all of their specialty truck boxes. Without adding an ounce of power to your current system the "Labyrinth Power Port" proves to be an easy and effective alternative to upgrading your low end on a limited budget.

This review is from: OBCON Dual 12" Chevy Ext. Cab 1999 - 2006 Speaker Box With Labyrinth Power Port (Electronics)

Looks very nice and fits perfectly. I put this box in my 2001 extended cab silverado with 2 rockford phosgate p1 subs. The box only comes with one little sheet of poly fill per chamber. Add more poly to each chamber and you will be good to go. I usually build my own boxes and decided to try this out. After buying material that is 70-80 dollars and the time it takes to put one of these boxes together, the 109 dollars shipped to my front door was well worth it. The box does not hit really low but the range of the box is very nice concidering the size of it. Just make sure you check the mounting depth of your sub before buying. The box says that the mounting depth is 5 3/4 in. The p1s that I put in have a mounting depth of 5.83 in, but they still fit without any modifications.

This box says 99-07 classic body and i have a 99 GMC with the older body style so i was hoping that it would fit completely under the seat.. The box extends out from the seat end about 2 1/2 inches but i went ahead and installed it and it still leaves room for the subs and the seat still sits flat so as long as you put the short people in the back you shouldnt have any problems. The port on this box is great it allows you to really feel the power of the speakers you install. The mounting depth may seem shallow at 5 3/4 inches but its more than enough for most speakers that you would need or want in a truck of that size.
