#1 Alpine Electronics PWE-S8 – Best Under Seat Subwoofer
Among all the subs on this list, this is the reigning champion. It has so many great points, so no wonder it’s #1 on my list. Not even Alpine can get around the laws of physics. It’s an 8” sub with a slim design that still manages to create a serious boom. It’s rated at 120 Watts RMS.
It gets the job done amazingly well. Even though it’s meant to be hidden under the seat, it still has good looks. Plus, you will be able to enjoy some great sound quality without sacrificing the trunk. Groceries have the full trunk while this sub can rest under the seat.
The installation isn’t hard. Plus, there’s a built-in amp, so you don’t have to spend a few weeks trying to find something compatible. The rugged construction will allow you to use it for many years to come.
This is why it’s top of my list:
- Built to last: The rugged construction means it can take some off-road abuse with no problem.
- Wow Factor: All you have to do is add this sub to your system, and your speakers will come to life.
- Compact design: It’s a small one, so it will fit under or behind the seat, making it a great way to get a massage while driving.
A few drawbacks that I’ve encountered:
I noticed that this sub starts to struggle at the low end. With this Alpine woofer, the limit is 35Hz. Nothing comes through below that threshold.
Also, it might’ve been just me, but there weren’t enough brackets to mount this woofer.
Alpine did a great job with this subwoofer, so no wonder people are installing it left and right. My share of rides where I’ve installed it is a Nissan Hardbody, Tacoma, 4Runner, Silverado, Tundra Crewmax, and many others.
Since it’s a best-seller, I’m not surprised that the stocks are limited. The last time I checked, there were only a few left. So, make sure to order instantly if there’s one in stock or someone else will grab it from you!
If you want something a bit cheaper, check out #2 on my list below.

Don’t get me wrong, you won’t do any hair tricks or rattle the neighbor’s windows, but you are getting a strong bass-producing clean and crisp sub. Best of all, you get everything you need to set it up in your car. There’s a wiring kit included with a built in amp and enclosure while at a ridiculously low price.

A few drawbacks that you have to know about:

For some reason, manufacturers love to put some insanely bright blue LEDs in the subs. Normally it’s not a problem if it’s under the seat, but if it’s in plain view, it’s distracting.
She’s a keeper because I’ve installed it in so many cars that I’ve lost count. Here are a few from my list of happy customers: Honda Accord, Jeep JK, Nissan Murano, Subaru Forrester, Tacoma, 95 Mustang, Tundra, Jeep Liberty and Ford F-150.

#5 Kicker 11HS8 – Best Hideaway Subwoofer
This is the perfect hideaway sub if you’re afraid that thieves would steal it. It’s small and compact, so you can easily put it below the driver or passenger seat.
It’s the best 8 inch Kicker subwoofer that has 150 Watts RMS rating. To my surprise this baby slaps. Of course, it can’t compete with bigger and more power-hungry subs, yet the space-saving shape is well worth it.
