P2D2-8

Easy install. Great sound quality. Made with good components. A little heavy in a good way because of the magnet which helps produce good sound. Perfect fit for ported box.

Awesome subs. Rockford Fosgate has been making high quality products for as long as they've been around. And these are no exception. Having owned Rockford, Sony, Sundown, Tantric, JL, and Kicker, I can easily say Rockford is one of my favorites. Obviously Sundown and Tantric are gonna have better SPL because of their extreme excursion and titanic motor size. But when it comes to sound quality and reliability Rockford takes the cake. I definitely could have gotten more sound out of them if I had tuned the box they're in a little higher, but at 33 hz they sound alright. I recommend if you're not a rap or dubstep listener to tune your box a little higher around 44-50 hz. I have 4 of them in a 2.6 c/f usable air space box. Nothing special, just well built, double baffled birch box. Pushing them with a Rockford R1200x1, birth sheet says 1310 watts, tuned with an O scope the amp is pushing 1287 watts clean power to them. Just over 300 apiece. I haven't metered them yet, but i'd estimate 140 db, maybe a little higher. Awesome subs for filling in the low end, but if you want alot of sound do at least 5 of them. And you can because they're cheap.

I have a 07 Acura TL type S, got tired of the crappy 8" sub that came with the car and decided to replace it. Well, I wont lie, I had to do some crazy mod's to get this in there to include taking a jigsaw to the bottom of the backdeck. Had to create a space big enough for the magnet to fit through. Well, after some other mods I had to do to get it to fit, even though this speaker is SEVERLY underpowered it sounds AMAZING... I went to a few different places in person to talk about something to power the sub with and found out that I would've done better getting a marine 8" speaker to replace it with because of the shallow mount and the fact that they don't need an enclosure (in case for anybody that's trying to do the same thing I did. However, I ordered an Audiopipe amp and from Amazon and saved about $100 there and as soon as I receive it will have PLENTY of power. I hope that this helps anybody thinking about getting this speaker, but I can only reply based on my experience. However my wife has 2 Punch P2-10's in her Mustang and with a 600 watt amp will rock your face off... I will update this review when I install my amp to talk about how much better it sounds. Hope I helped!

This review is for a Rockford Fosgate P2SD2-8. I have previously purchased the older version of this subwoofer from around 2003 from crutchfield, and that version died a little bit before this review. It lasted a long time. But that version only required 150w to produce 83 decibels, this version requires 250w. Seems odd to me that the newer version is less efficient than the older (or very older in my case). Anyway, it fit my box with the screw holes in the exact same position. I heard a distortion in one of the two subs in my box. It was from the sub on that side drawing air through the drill holes, or maybe the larger hole. A large amount of silicone fixed that issue. So if you hear the sub distorting, try using more silicone around the the holes. This was my second purchase of this item, from Amazon itself. Previously I purchased from a third party seller, Absolute Pro Music, which sent it via USP with signature verification. They did not tell me that a signature would be a requirement for a $100 item. I've previously purchased camera lenses for $x,xxx without needing a signature. WTF, right? So when UPS came and I wasn't there, it got sent back. It took about two weeks to return back, and then I waited two weeks for a refund. A whole month. Eventually I contacted amazon customer support and forced a refund. Just make sure the "sold by" field is by Amazon, and not a third party. I have no idea why they had a third party for this item by default even though amazon sells the item themselves. You can select Amazon in the "Other sellers on Amazon" list.

The sounds great. Installation in my Nissan Sentra was a pain in the butt :/

I had an early model pair of these in my SUV and played them until they wore out the surround/suspension, they sounded killer! I bought another set to replace them and the new set had a new style rubber surround and at first they were tight and had weak bass, I thought there was something wrong with them but after a few weeks they started to loosen up and sound good! I just bought another pair of these for my new car. They seem pretty stiff out of the box but they should loosen up after a few weeks.

Installed in a well sealed enclosure at .35 cubic feet after woofer displacement using a Rockford PBR500X1 with PEQ knob wired to 1 ohm. Pros: The sub looks great when using the Rockford grille. It can be ran at 1 ohm for use with PBR500x1 and PBR300x1 amps. After some tweaking it did start to sound ok. Cons: The mounting ring around this sub is made of plastic. Even with very little force I cracked it in two places using only a hand driver, supplied screws and adapter. When sub was first fired up I let it play at a normal volume for an hour or two to loosen the suspension a bit. It is very tight when new. I then started fine tuning the gain and crossover. It made a very strange noise almost like it was bottoming out. I added 8 ounces of poly-fill to enclosure and the noise seemed to subside. Hopefully after it has time to break in the sound will improve. My first impression is pretty disappointing. I expected better performance using all Rockford equipment and building to their specs.

Installed this in the stock box that came with my '04 Ford Focus SVT. Did have to heat form the back of the box a bit due to the depth of the voice coil but it came out great and the fit is just right. Remember that this is a dual voice coil setup and requires your wire up both coils, one set of plugs on each side of the magnet. I mention this because I was teaching my son about stereo systems during the install and had to point it out to him, lest he get something similar and wind up blowing something in the process of overlooking the wiring hookups.

Works really great just a bit bigger than the opening had to modify the outer diameter is bigger than the oroginal but sounds grest

気持ちいい音で、鳴くので買って良かったです
