Description

The R2SD4-12 sub features a 12" mica-injected polypropylene cone that works with a high-density poly-foam surround to punch out fat, deep notes. This shallow-mount workhorse will handle up to 250 watts RMS, with a mounting depth of only 3-5/8". Rockford Fosgate stitches the tinsel leads that carry the signal to the voice coils directly into the cone, so they'll hang tough through heavy use. The stamped solid-steel frame offers the same venting found in standard-mount Rockford Fosgate subs to keep this sub running cool.

    • Damn good subs
They sound great and hit hard. 250 watts rms and I had 325 watts going to each one in a sealed downfiring under the seat box a grass bit oversized so they could reach a little bit lower bass frequencies. I could be heard coming from about 3 blocks away.

    • Sounds horrible
Bought these had less then a month and both subs just stopped working. Amp was only on gain setting 3,anything over that the subs bottom out and distort bad. Only using a 500 watt Amp. Hooked up a spare 6x9 I had laying around to make sure it wasn't the Amp and it worked. Subs don't smell burnt still move freely by hand, just no sound ... show more

Very happy with this purchase. Great price and sounds great. I have to turn them down sometimes on a 500watt amp.

Sounds great. Added to my 08 quadcab ram in a stealth box. Great quality. They hit hard for a shallow sub.

    • They didn’t even work.
I’m actually pretty upset, I paid $160 for 2 speakers and one of them is blown and the other one didint even work. Not good quality speakers in my opinion.
