Prime subwoofers are ready to rock and are the perfect first step into performance audio.The Prime R2 12" subwoofers have a peak power rating of 500 watts and a continuous RMS power rating of 250 watts. This makes them an ideal subwoofer for anyone looking to add some modest low end to their car audio system. The Prime R2 drivers feature an anodized aluminum voice coil formers for extreme heat dissipation that allow the driver to perform at optimum level during long hard hitting sessions. These subwoofers are the way to go when looking for a woofer that is built with quality & performance in mind and has been designed by industry's leading car audio manufacture.
These woofers, like their Punch brethren, are built using many of the same speaker technologies that Rockford has been famous for over 30 years for and you won't break the bank buying one. Simply put, the Prime seriesof woofers are held to the same standards of quality and performance as any other Rockford woofer but delivered at an affordable price.
Anodized Aluminum Voice Coil Former
By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.
Conforms to CEA-2031
Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.
Stitched Tinsel Leads
To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

Mounting Depth is NEEDED
One thing that NEEDS to be in the description is the MOUNTING DEPTH of the box. This is CRUCIAL for determining which speakers will actually fit in the box. Once I received the box, I estimated the mounting depth to be somewhere like 5.5" for the sub. So this does limit certain models of subwoofers, but the one I chose fit perfect. I also enjoyed that this box came with poly-fill. Sounds great with my Alpine SWE-12.

A Super super happy man!!!
I bought this Single 12" Subwoofer Angled Truck or Hatchback Box Enclosure a few days ago. So I cant explain how much happy I'm listening my music with this box, I'm an immigrant from Colombia who like to listen music such as Salsa, Reggueton, Merengue a real Latin guy. The sound is something so crazy (Perfect Sound - Space) in my car, Now I'm able to move all the toys of my son in my 2010 Toyota Matrix. If you want to have a good space & sound this is the box for you. Don't be scary for the size of this box. ;) I'm a happy Colombian.

Nice Box
I purchased this box to put a Hifonics HFX12D4 in. The box is well made and falls within specs for the sub. The carpeting, cutout, poly fill and terminals are high quality. I added about 5 oz of polyfill to make the sub think the box is bigger. The box also has a small footprint and fits easily in the trunk of my Yukon. This combo is matches up well and is highly recommended. Plus, the pairing offers a great value if you want strong bass on a budget. Sonic did a great job with the shipping :)

Good Product for the Price
Good construction but it really flexes from my Rockford P3 shallows so I had to reinforce it with resin and fiberglass

Works great.
I bought this speaker box for a mustang but I ended up with it in my extended cab f150. I raised the rear seat up 2 inches and put in a alpine sub. This box hits hard and it is sturdy. It also looks nice in my truck.
