Rockford Fosgate P2D4-10 Punch P2 DVC 4 Ohm 10-Inch 300 Watts RMS 600 Watts Peak Subwoofer

Great subwoofer, it exceeded my expectations. At first I installed it inside an Atrend sealed Bbox, which is. 85 cubic feet and within Rockford Fosgate's specifications, it sounded ok since I installed it inside my trunk. However, I wanted more bass using the same sub so I opted for a ported box instead. Thus I purchased a Sound Ordinance box from Crutchfiled. It has 1.4 cubic feet of internal volume the recommended space from Rockford when using ported boxer. This box was the only one with the correct internal volume I could find in the internet. Once I installed it, wired it, and played some music, I immediately noticed the difference. The P2 hits harder and with longer deeper bass notes I can now feel inside my car. My Alpine amp is tuned to the same settings as with the sealed box, but the sub is louder, because power efficiency is better achieved with ported box. So long story short, if your mounting this sub in a sealed trunk like mine separated from the passenger compartment go ported with the recommended internal volume. If you however, drive a wagon like a Scion Xb or something similar, a sealed box will hit hard and you'll feel and hear it. I recently installed a 10 inch P1 in my wife's Xb using my old Atrend Bbox powered by an MB Quart 400 watt rms monoblock and it sounds stupendous. Well I hope this helps and you are able to come a conclusion about your purchase and how to install this great sub based on your application.

I purchased one of these 2 years ago to go with a Memphis 5 channel amp that puts out 400w to the sub channel and mounted the sub in a custom fiberglass enclosure that is right at 1.0 cu ft air space. (which sounds better than the .7 I had) this sub still sounds fantastic! I've been building car audio systems for over 20 years and have installed and listened to just about every subwoofer out there and I have to say that this sub performs with the best of them. It puts out the bass of a high end 12" woofer and would honestly imo out perform two mediocre 12s. Not to mention this sub looks fantastic when installed. I would definitely recommend it.

Love this sub!!! Got it in a sealed single sub box with a 1200 watt mono-block amp kicking the snot out of it. Also a nice Pioneer head unit. Sounds amazing!! I listen to a lot of EDM and stuff thats very bass intensive, so i really put rhis thinf through the rigors! Accidentally blew my first one (definitely due to clipping the input of the amp) and immediately reordered a replacement. Had people comment that it's louder than people running 2x12" which it absolutely is!!!! 😁😁😁😁

I installed this in my camper van over four years ago and am very happy with it. It gives me the punch I love and I swear it sounds better over time. It really compliments my sound system. I do wish it came with the cover screen, which I think is necessary for protection, at least in my application.

Awesome sub im feeding it 300w at 2 ohms hooked up to a 5 channel amp and it shakes the inside of my car like crazy, u can feel it a little bit outside but not so much, but its fine because i only wanted to get a full sound out of it not wake up my neighbors, it doesn't hit some of the lows but i knew that from the reviews. Overall all a great subwoofer if you're looking for a full sound
