After years of using different subs, sizes, box types (sealed, ported, bandpass, isobaric, etc). As a bass lover a sealed 15 is the way to go for nearly all genres.

I’m still using the same subwoofer I bought in high school back in 2005. The infinity kappa 12 vq. I love that thing. It just goes from car to car to car lol.

Try to build a box that is to the specs of the speaker and it'll sound even better

THANKs!!after weeks of back and forth your video just convinced me to go sealed and face them to the rear,i have 2 jbl GT bass pro 12 s now ,i had bought/built a custom sealed box and ive been wanting to transplant the woofers and amps for awhile but wasnt sure,thanks!

Thanks for the video The only one I seen break it down like that 2 thumbs up👍👍

I have done all these same tests as you and got the same results too. Rear facing always seems to improve "in-car" performance. Ported for more loose low end. Sealed for more accurate punchy bass. However, ive now gone for completely old-school method. I made up a 25mm thick parcel shelf which fits tightly and seals the entire hatch to form a very large sealed box effectively. I have 2x 12's in the shelf and for me its the best sound over all. Very punchy tight bass and insanely loud if you want it to be. For me offering the best Clarity overall combind with the other speakers in the car.

Ported can go much lower if tuned properly but sealed will offer better sound quality and accuracy. However it’s still possible to go low with a sealed box but you’ll have to build the box very large. For example, my friend and I built a 3.25 cu ft sealed box for a kicker 12 inch sub and it peaked around 28hz.

Dude its good you didn't pass out with the car exhaust... the video was great

You may also want to look at the Cerwin Vega Vpas 12st. It's a donut style sub enclosed with a built in amp. JBL also makes one called the JBL Bass pro Hub. They literally fit in your trunk or hatch in the recess of the spare tire. Totally stealth and leaves you with all of the space in your car. I have the Cerwin Vega, and it sounds really good. Back in the day I had a full on system, and this doesn't give me buyer's remorse. Like you, I have neighbors to consider, and also I'm not in my late teens and early twenties anymore. LOL. I don't need to shake the ground.

For science!!! Good video Jake! Love the object permanence joke 🤣

Sealed box tends to be tight, accurate bass, and ported tends to be louder and sloppier bass.

I have a 2015 VW beetle hatchback. I've tried every position and I found that mine sounds good on the side wall facing the other side. So sideways. DB competition 10" in a ported to spec's and it hits hard and sounds good on rock, country and hip-hop music.

Sealed boxes are my favorite as well nothing like hitting the bass notes and sound is on point

I just picked this sub up for $80 and a custom sealed box for my accord for only $40. Never had a sealed setup so this is literally perfect. Same exact sub.

I think if you don't mind using up a lot of the space you have you would be very happy with a 1/4 wave transmission line box. They are known to have a great flat bandwidth of a sealed box but more of the output of a ported.

"Amphetamine aficionados..." BWAHAHAHAHA!!!!!!

There is always a kid with a honda civic when you need it🤣🤣🤣🤣

First time watching one of your videos and that intro made me laugh you got a sub for that

Love it man

And that’s why I run sealed. Listen to a variety but emphasis on metal and I need that thump on the higher kicks
