Noticeable difference with factory head unit

I am only able to give it 4 stars at this time because I'm only pushing it with the factory head unit. After I get an Amp installed I know it'll perform up to the stards it built for.

Good upgrade

Needed a shallow woofer for my Tundra and this one fit great. The JBL system that came with the truck was ok (stereo needs to be replaced) but this speaker is an upgrade (old one final blew out)

Great OEM replacement

This is a really good speaker for those that are wanting to swap out their factory subwoofer for something better and more clear. I returned it though due to having an amplifier bought for me that could've or would've blown it if I had connected them up. If you know you're going to stay with the stock head-unit or mildly power with an amplifier that's rms is equivalent to this one then this is your choice. Can't go wrong with RF, nor with Crutchfield for customer service & support. Attached pic is for the oem woofer on the tenth gen touring & type r civic hatchback. That's the amount of backspace you have available in the oem box. A bigger sub will fit but you'll need to plan for poly fill, an extension ring, and possibly modifying the panel in front of the woofer.

Big improvement!

Night and day difference vs. the factory sub. The factory sub is 2 ohms so I wired the dual 4-ohm voice coils in parallel. In the factory location we now have a much more hard hitting sub, even though it is still in the rear-deck, free-air location.

2021 Honda Odyssey Rockford Fosgate Sub Upgrade

This was purchased to upgrade the factory subwoofer in a 2021 Honda Odyssey EX. I wired it to 2ohms to match the factory speaker and used the factory amp. Install instructions were flawless from Crutchfield. All the recommended tools were perfect and made the job a breeze. Anyways this speaker is of very high build quality. Came with detailed instructions, all the correct hardware and impact driver bit. Sound has improved. Has a richer more full sound than the factory unit. Can handle more volume without getting muddy. A perfect upgrade and I'd highly recommend buying this speaker as a factory upgrade for a stock stereo

Good sub but a little pricey

I replaced my stock sub in my 2019 Honda Civic Type R as this was recommended to me and while it was an improvement over the stock sub, it definitely needs an aftermarket amp to better power it. All in all it's a good subwoofer but I think it's a bit over priced.

Great sound at a great value

I was in the market of a subwoofer to replace the blown unit in my 04, 4runner limited w/JBL. I was able to use the existing OEM amplifier and the speaker puts out great base. Very happy with this purchase.

Working well so far. If it came with a grill/cover I would have given it 5 stars. Liked the way the wires hooked up on both sides, and it looks really sturdy. I was able to mount this in the center console of my vintage Porsche 914 and still have room for the center console gauges and a small amplifier.

Perfection!! . The sound of my Rockford Fosgate speaker surpasses the JBL speaker that was previously in my 4Runner. I could tell the first minute of hearing sound from that speaker that I had made the right choice. If you love loud music like I do, I highly recommend Rockford. Although my other speakers are sounding just fine I will be replacing them in the near future as I now know what great sound is! Crutchfield is spot on when it comes to professional customer service and shipment practices. Many thanks !!! - I am now back to listening to Alan Jackson music as loud as I want! :) "A happy customer is a repeat customer" I'm a happy customer!

Tight clean bass.

Awesome Product and customer service. Bass is a lot more than what I expected, big difference. Tight with no distortion. 2002 Yukon XL with stock equipment. Now considering upgrading the rest of the door speakers to match up to the subwoofer. So back to Crutchfield for more.

Great replacement for 2001 Suburban / Yukon XL

I purchased this 8" P3 to replace the blown subwoofer in my 2001 Chevy Suburban (also compatible with Yukon XL). After removing the trim ring edges with a Skil jigsaw it fit perfectly in the original enclosure and sounds awesome! It's great to have bass in the car again even if it is still pushed by the factory amp. The process to replace the subwoofer takes 60 - 90 minutes and requires you to cut the trim ring on the Rockford Fosgate speaker. This cutting voids your warranty so be sure you are comfortable with this risk. Ideal Tool Set: Panel tool or metal putty knife, phillips head screwdriver/bit, cordless screwdriver/drill, jigsaw with blade (I used a Bosch basic metal blade (U118A)), and a small drill bit about half the diameter of the P3 mounting screws. 1) Remove the four trim pieces in the Suburban (search WWW for videos). 2) Remove the existing subwoofer. 3) Using the Skil jigsaw trim the exterior plastic / metal ring on the Rockford Fosgate leaving only the screw holes. 4) Jump the two terminal sets on the speaker like you would a car: negative to negative and positive to positive. This makes the speaker 2 ohms for the factory amp. 5) Hold speaker to enclosure and drill four new holes. 6) Strip and attach the factory speaker wire to one set of the speaker terminals, screw into place with the included P3 mounting screws, test, and then replace the four trim pieces.

Great bang for the buck

Replaced my factory 8" and I was immediately impressed by the sound it created, not the best at catching lows but for the size it does a decent job, I also am still working off the factory amp which is for the sub exclusively I'm my 2005 Lincoln Aviator, I'm sure if I updated the amp it would be that much better. The mids are extremely crisp and the break in time was relatively short. My next step is to upgrade the door speakers which i will also be ordering from Crutchfield in the near future.

Serious for an 8 Inch sub!

Due to some modifications that I didn't expect, I haven't had a chance to install this sub yet. However, right out of the box this speaker seems like it's one serious machine! Heavy and seemingly well made. I plan to update this review after install so can offer 5 stars.
