Rockford FosgateP3SD2-8 8" Dual 2-Ohm Punch Series Shallow Mount Car Subwoofer

Perfect fit and great sound in my 2005 4Runner. It works great with the factory JBL amp. To my untrained ears, it sounds better than the JBL subwoofer ever did. My kid was laughing because the new sub made his seat "bounce".It was an easy install. I found a guide online to remove the trim panels to get to the subwoofer. Once you're there, you just unplug the factory sub, strip the wires, and plug them into the Rockford Fosgate sub. The black and red wires go into the red connections on the sub, and the green and yellow wires go into the black connections. First time I connected and tested, the sub was working but not making much juice, so I switched wires to the opposite sides (i.e. black and green wires moved to right side of sub, red and yellow wires to left side). After doing that I tested it again, and was it ever thumpin'. I had to drill six holes to mount the new sub, which wasn't a big deal. The most tedious part was screwing the sub in, because I was worried I'd slip and tear a hole in it. Finally, you have to reinstall all the trim panels. Be careful with the 12-volt outlet because it seats really close to the speaker and the connections on it could poke a hole in the face of the sub. Overall replacement time for me was just under 3 hours. I went slow and took my time to make sure I didn't break any connections on the trim panels. I'd suggest a trim kit tool set. I've had one for years and it's so much easier than working with screwdrivers.

I used this with the PBR300X1, which is now discontinued, but still a great amp. This speaker shines in small boxes, often factory upgrades. I used it in an '02 Explorer and a '21 supercrew with the Ford branded box. In both cases, this was a huge upgrade from the stock sub. It will not rattle the neighbors windows, shake fillings loose, or impress your buddies, but it will provide a great foundation for a balanced system. Volume and loudness are highly subjective, but in my opinion you're better off with this and some dynamat than a pair of 12" subs with 1200W each.

The factory sub on my 2004 4Runner Limited blew. This one works great. I ordered it from amazon and then had it installed (I have too many thumbs to do it myself...) for me. It was plug and play, outside having to drill new holes. I watched while he did it and it was pretty straight forward. Took about 35 minutes to do. No need to buy anything else. If you want a good sub to replace the factory one, this one will do you well.The sound is very good. It is better than the factory JBL sub. The bass is more pronounced and sharp. At first I kind of wondered if it was too much, but it isn't. It doesn't dominate the music. Just gives more punch to the bass. I suspect the factory equipment really isn't pushing this thing too much. It is really nice to be able to listen to music again and not all the scratching, popping, etc.. of the blown sub.One other comment. I was debating between this and the Pioneer sub. The Pioneer sub was $20 cheaper on amazon. In hind sight, I'd probably give strong consideration to buying the Pioneer instead. This isn't a reflection on the RF sub. It is mainly because I don't think the factory equipment pushes the RF sub that much. I'd probably been just as happy with the Pioneer.

I have never messed with any "real" type of speaker installation so when our 2003 Toyota 4-runner sub woofer blew I looked at diret replacement which was CRAZY $$$$! So Amazon to the rescue. This thing is built like a Brick S*** House!Very nice !Fits and functions beautifully. The install was a little slow but on You Tube there is a video that shows how to remove the rear passenger side interior panel which is in itself time consuming but NOT impossible by any means. The speaker does not align with factory holes but using the new cover holes to first locate the (4) holes then using those holes and the speaker I was able to pick up the rest of the holes.Use 2 sided tape for for placing thin foam on outer edge of new cover. ALWAYS use the screws included after drilling first. Careful with screw gun not to strip, always seat srews with screwdriver.And finally...IT SOUNDS GREAT ...Great Bass response!Rocks!Thanks Amazon and Rockford Fosgate!

I knew I wanted to change out the OEM sub, I knew I wanted to keep the OEM box, and I also knew I didn't want to change out the OEM amp. I have the Ford Explorer Limited 2013 with the 10 speaker system which already sounded good.However, I knew due to age, and usage that it was time for upgrading the speakers and I decided to start with the subwoofer.I watched videos carefully on how to take apart the panel, so after watching so many videos I did it and was able to do everything in about an hour.The Ford subwoofers are dual 1.2 ohms, so the dual 2 ohms are perfect because let's face it, you'll never find 1.2ohm woofers and if you do they will not fit and on top of that they are very expensive!Now, I added poly fill inside the OEM box and it made a difference in sound completely. The bass sounded tighter and more real, it filled the cabin more compared to the OEM one.The only fear I had was that due to the difference in ohms, that there might have been some clipping. But not at all, I played hip-hop, house, jazz, alternative, rock, Spanish, Italian and it all sounded perfect.Now, I will say this, I don't know if this sub would work for the regular sound system, or even the step up from regular. I have the 10 speaker Sony system which has a higher rating of wattage compared to the others.This was an amazing upgraded to the factory system. Enjoy
