Best Car Component Subwoofers in 2020

Rockville RW10CA 10" 800 Watt Under-Seat Slim Amplified Car Subwoofer +Wire Kit Review:

I have this professionally installed in a 2001 Toyota Avalon. Overall I don't think I can complain for the price. It's well built, mostly fits under my seat (even though 60% of the seat has 0 clearance underneath), and way louder than I need it to be! I keep the volume on the sub well below 50%, maybe even closer to 25%. It thumps fairly hard through the seat and it can really rattle my review mirror if its turned up past 50%.

That being said - to my ears it just sounds a bit boomy and muddy. I don't know if it's just the stock JBL system in my car needs to be upgraded too, or if the sub just doesn't sound particularly amazing. To my ears I don't feel like the frequency response is covering much of a spectrum. The low end feels like it's missing a true bottom end and I'm not hearing that much detail in the low-mids. Then again how much can you really expect from a pancake subwoofer? I was scared that If I had it installed in the trunk it would be too quiet, but after the fact I'm wondering if it would have been better in the trunk.

All in all, I still think it's a great value. I saved a ton of money and space vs what the installer was going to provide. It certainly is better than not having a sub at all like I did before. I like my music to be strong and detailed, not shake-the-neighborhood-make-everyone-hate-me kind of loud, so it's got way more boom than I need and takes up almost no space.

Skar Audio Single 10" 1200W Loaded SDR Series Vented Subwoofer Enclosure | SDR-1X10D2 Review:

This is a great sub for your vehicle. The only thing is it is huge the box takes up most of the back seat in my crew cab pickup but the sound quality is worth it. It was a simple install but that depends on your vehicle and how you run your wires. It got a nice little adjustment knob so I can turn it down when I’m pulling in my neighborhood and stuff like that do I don’t make the neighbors too mad lol. This thing hits hard. Vibrates my truck and is a very clear sound, NOT a sloppy bass sound!

Rockville SS8P 400w 8" Slim Under-Seat Active Powered Car/Truck Subwoofer Sub Review:

This Sub (not really a Sub but whatever you want to call it) is very nice for the price IF you have a factory stereo or an aftermarket stereo with no amps connected..But you shouldnt expect this thing to play real loud..I got it hoping it would be a little louder for my system..have a 100x4 amp with Alpine 6x9s and 6.5 door components,,at low to moderate sound it is fine almost perfect but if you have a loud system when you play it loud this speaker will got overpowered . And thats with the gain at max and the bass boost at near max.
I placed it behind driver seat in a 04 Grand Prix...under the seat I felt it didnt sound as good..I doubt I will keep it in my current set up but will probably keep it for the second car since the freight to return it would be to much to merit returning it.
I give it 5 stars for the price and performance on non amped stereos and 3 stars for How much I like it in my system
If you have a non high powered stereo and you wont put it in the trunk (you cant tell its there in a trunk) then for the price I think you will love it.
UPDATE::: Ok I have had this sub for about 7 months and have had hooked up 3 different ways..( all we're with my above mentioned speakers and amp))
FIRST.was connected to factory radio which is what my review was made..then SECOND OFF I installed a Sony deck and it made the sub sound a noticeabley better and was little more impressed with the sub..THIRD OFF I went back to my factory deck but installed a Clarion EQS755 equalizer and OMG what a difference unreal how much bass this Sub puts out now! I even had to turn the Sub gain down to 1/2 way ( I had it at 3/4 before EQ)and again it sounds unreal for a 8" Sub (again I have it behind front seat on rear seat floorboard)BUT for some reason it kept cutting off with the Clarion don't know why so I am back to having it connected to the Sony Deck and I will say even when I have it up very loud you do notice it and t makes a difference ( when I turn it off with the deck you see what a difference it makes.)
Through all my connections I would say a aftermarket deck will make the most difference as compared to a factory deck ( it got drowned out easier with the factory deck)
I don't listen to rap or hip hop mostly hard rock / rock .. if you listen to rap and hip hop I doubt you will be as impressed as it struggles with super low bass ( but it's a 8" sub so I doubt anyone would think it would rock with rap or hip hop)
If it lasts its an absolute steal now! I now give it 5 stars!

UPDATE #2…........
I know have 2 of these installed in my car 1 behind driver seat and 1 behind passenger seat and adding the second one made a big difference ( no duh! Right?) And with adding the second one the subs never get "drowned out" by my amped speakers and at times it's to much bass to be honest but loving this lil sub big time! No it's not "audiophile" quality and it doesn't hit like two 10s or 12's but with the subs on the floorboard I don't have that God awfull trunk rattle sound on the outside that I have had in the past when I had subs in the trunk (not to mention I can use all of my trunk without a huge sub box in it) my rear view mirror vibrates like crazy at times ( it vibrated when I had just the 1 also) but no it won't vibrate your side view mirrors in case you were curious...people have gotten in my car I asked what subs I had in the trunk ( they didn't notice I had 2 of these on the rear floorboards). I know most people don't plan on getting 2 of these (again 1 will be noticeable) but if your thinking of getting 2 or adding another one to your excisting sub.. Do it! Also I don't currently bus the amp gain dash knob but since my decks sub volume adjustment seems to be all or nothing I plan to add the knob but will wire both subs to 1 gain knob..

Rockford Fosgate P300-12 Punch 300 Watt Powered Loaded 12-Inch Subwoofer Enclosure Review:

I had this sub in my car for 3 weeks before I got it to turn on for the first time and 10+ hours of frustrating, hair pulling installation hours spread out over the course of those 3 weeks could have been spared had I just known a few simple things to begin with.

Bear in mind, I work with audio and live sound for a living, so I thought this would be cake. But car audio installation is a different beast. So here's my 2 cents that might save another customer hours of aggravation if they plan to install this themselves.

1) get an ANL fuse that can handle 60-80 amps. Running 8 gauge power to your battery with no additional fuse to separate it from the source can be dangerous and the fuses in the sub aren't going to cover this.

2) this sub had a BUILT IN LINE OUT CONVERTER, therefore you do NOT need one of those little LOC boxes that most people buy for their subwoofer and amp kits.HOWEVER, The cables that come with the sub make you THINK you need one because they are RCA female to high level speaker input.But there's a bridge within the amp itself and you will need to cut this cables RCA ends off and splice the R positive and L positive, R negative and L negative into your cars speaker harness using a T-TAP and quick connect that you can get from any advance auto parts.

3) Tap the high level input into your cars existing subwoofer, NOT YOUR REAR OR DOOR SPEAKERS, or it will sound like crap.

4) you DO NOT NEED TO RUN A REMOTE WIRE. This was my mistake but I misread the instructions and wasted SO much time attempting to run a remote wire to my head unit and fuse box that I didn't even need, because at the high level input it has an intelligent turn on that senses audio and turns the sub on by itself.

Break the sub in slowly, do not turn up the setting for a few days and let that speaker move air without going crazy. Once it's broken in, enjoy the little powerhouse that this lightweight little sub is. In my Civic Si it rattles my windows and fills the car with the most crystal clear, tight heavy bass without being overwhelming. It's perfect!!

Rockville SS8P 400 Watt Slim Under-Seat Powered Car/Truck Subwoofer Sub+Amp Kit Review:

Wow! The reviews are spot on. This enclosure does a heck of a job. I had done a ton of research on powered subs, including Alpine, Kenwood and Pioneer 8'' enclosures. I was concerned with buying an unknown name and, based on the Amazon reviews, that this Rockville would not have any punch. I am NOT disappointed! The sub is well built, solid metal casing, and sounds tremendous. Definitely captures clear, low ends sound and fills the car with sound. Installed in a jeep jk, 80 mph down the highway and still sounds great. Easy install and it takes up no space. Plus, there is a bite and bump to the low end. You wont rattle windows, but you definitely know, and feel, you have something. Only draw back is the remote volume control is plastic and feels cheap....but who cares, crank it up and let it roll. Dont hesitate, for the price, this is amazing sub to add to your system.

BassPro SL - JBL 8" 125W RMS Powered Under-Seat Compact Subwoofer Enclosure System Review:

This is a great subwoofer/amp combo. Some reviews stated it didn't really have any "thump" but it has more than enough for me, as all I wanted was a nice way to fill out the lower end. The quality is fantastic (as most anything made by Harman/Kardon is) and the sound is great. I installed it under the left-rear seat in my crew cab pickup and am very pleased with the result. I really like that I didn't have to find room for and amp, and a speaker box. It's a great product, and the price from this vendor was much better than others! Great shipping as well!

Rockford Fosgate P300-10 Punch Single 10" 300 Watt Amplified Subwoofer Review:

In the mid 1990s, I had two RF Punch 12s in a bandpass enclosure, driven by a Punch amp. It was amazing. Here I am in my 40s, missing that kick in my commute. Thus, I ordered the P300-12 for Father's Day. The next day I installed it in my mid-life commuter car--a Toyota Prius. Yeah, that's right--a Prius. It saved me 5k in gas last year... I'm over it. Anyway, the P300 exceeded my expectations, especially in a small car like this. I run around with the knob set at 50%, and it's everything I remember RF being, except smoother and less bouncy than the bandpass I had in my lowrider. Definitely the booming-est Prius in the gated neighborhood. My wife suggested this purchase is the sign of a possible mid-life crisis. I told her it's cheaper than a Corvette or a boat. She agreed. So if you see a cool Prius bumpin' Bone Thugs n' Harmony, driven by a responsible and practical man... that's me.

Oh... the install was easy. I followed the advice from previous reviews and ran a remote wire with the coax and everything worked great. I'm pretty sure this thing cracked my windshield due to the harmonic vibration of the rear-view, and I'm totally okay with that.

Single 12" Kicker CompC Sub Package with Kicker 11DX250.1 Refurbished Amp & Vented Enclosure Review:

Perfect match for my daughter's existing kicker speakers in her car. Great value for the money. Hits hard, yet smooth.

MTX TNP212D2 12" 1200W Dual Loaded Car Subwoofer Audio Sub+Box+Amplifier+Amp Kit Review:

I helped my son buy this speaker kit for his first car. We figured this would be a good starter speaker kit for a cheap price. This kit does come with the amp wiring kit as well, it just ships separate. We got everything installed in his car and then followed the amp tuning instructions on MTX's website. Once the amp was adjusted we couldn't believe the sound quality from this amp and speakers. My closest neighbor who lives about a quarter mile away could hear the bass. We are very happy with this purchase.

Sound Storm LOPRO10 Amplified Car Subwoofer - 1200 Watts Max Power, Low Profile, 10 Inch Subwoofer, Remote Subwoofer Control, Great For Vehicles That Need Bass But Have Limited Space Review:

*edit* 10/28/15 - 16 months in and unit is still running great!

I have been running this in my 96 4Runner for about 5 months now.The sounds is decent, a definite improvement. It really fills in the lows and rounds out the sound. I wasnt expecting huge sound from this because of its size and price, but it does a great job. I used to have an infinity basslink II in the trunk of my mustang, which sounded slightly better, but I did not want to lose ANY cargo space this time. In my car, it doesnt really shake mirrors or anything, but you can surely hear and feel the bass now. I generally use it for rock and alternative rock, and it really brings out the bass guitar, and you can hear/feel the kick drum. The sound quality isnt the greatest, but it is inexpensive and fits under the seat...

It was very simple to install and setup. I used the inexpensive Boss wiring kit amazon sells for the installation. I haven't seen any reliability issues with the unit, if i do, I will be sure to update my review. I thought I had an issue, and the SoundStorm Labs/BOSS stepped up and took care of it (my shipping expense though). It was determined that the issue was a intermittent ground connection on my installation. The only thing, is I am sure this unit isn't really 600w RMS, it has a 25A fuse, so perfect efficiency it could possibly output 25Ax14.4V= 360W or continuous power. It is one of the cheaper under seat subs out there, and It has not disappointed me yet!

I installed this and an Alpine head unit at the same time. My plan is to use these 2 for a while until I can get some nicer speakers and an amp. the Sub combined with using the HPF on the headunit provides a huge sound improvement and will help avoid blowing the stock speakers by pushing too much low frequency. Seems to have good results so far. I generally set the LPF to 60Hz on my head unit and it seems to work well for me.
