Rockford Fosgate Prime R2D4-10

Crisp & Breathtaking Bass

Paired up with my Boss R1100M and Belva MDFS10, this makes the best single sub setup for the money! Bass is perfect and not overwhelming like my 2 12s were. Very smooth bass. 100% recommend. This is in my daily driven car and I've been running it for a while. Rockford Fosgate

Great sound

Best sub I've used. Have tried infinity, alpine, crunch, and some off brands in the same price range. This one sounds way better. Deeper and louder. Very tight, crisp. In a 1.1 cu. Box. 500 watt amp

I was looking to put some bass into the sound system I was building for the truck. As I have gotten older I was wanting a good SQ set up. I chose this sub for its value, wattage handling, & the dvc. I built the box and got it powered using a channel amp and it has delivered. I cannot comment on the durability as I have only had it a month but so far so good.

Very good sub

These subs hit nice with the right power also in a ported box. You can max these out too with sound. Nice and gives you the sound quality you want.

Good Entry Level Sub

I always build my boxes myself never buy prefabs. I built a box sealed at .8 and the sub sounded really well for $50. Rockford did a good job with this one. Definitely fills up a 1998 mustang. I just ran one and it's lasted well for two years now run on a 200 watt amp. I would buy again if on a budget.

My brother bought me this sub for my birthday, he has dual 12 inch hifonics running 800 watts a piece. My single 10 inch can keep up with his dual 12's if you are looking for good reliable bass I would say that the r2d4 is your best bet.

nice loud sub

I have one of these in a custom ported box tuned at 40hz powered by a boss 1100 watt amp. Im giving it 250w rms and it sounds great at lower volumes. When I really crank it up I can hear it outside the truck and it rattles body panels, but it dont have as nice sound quality at higher volumes. Overall its a good sub and the price is great.

Great sound and bass also great quality speaker for the price.

Very clean sound..

This sub hits hard, has some shake to it, and is very clean deep sounding.. Its absolutely amazing for the price.. Rockford fostgate did it again.

Good Value

This sub sounds great. After roughly 15-20 hours of break in time it really starts to shine. It's in the back of my crew cab Tundra in a passive box tuned to 34 Hz with a Dayton Audio 10" passive radiator. It's feeding off of a RF 300.1 and after breaking it in it keeps up with the amps power. I have bottomed it out before during a torture test but the voicecoil definitely handled every bit. The duel voicecoil is nice too for extra wiring options.
