Active Car Underseat Subwoofer - Need Opinions

[OGajoDaPolvora]

Hi,
So I've got a 3dr Suzuki Vitara (Or Sidekick for you American fellows), and as you may or may not know, it's pretty small.
I've upgraded the front and rear speakers, but it's lacking a LOT of bass, I have HPF on all speakers because otherwise all of the plastics would start to rumble all over the place.
So I've researched a bit and made a list of potential subs that I would buy, but I want an opinion.

List:
Infinity BassLink SL - Infinity BassLink SM | Powered 8" Under Seat Car Woofer
JBL BassPro SL - JBL BassPro SL | Powered 8" Under-seat Car Subwoofer
Alpine PWE-S8 - Bafle autoamplificado de 8” (20cm) e 240W com deteccao automatica de entrada de altavoz. - Alpine - PWE-S8
Rockford Fosgate PS-8 - Punch Single 8" Amplified Loaded Enclosure | Rockford Fosgate (R)
Pioneer TS-WX400DA - https://www.pioneer-car.eu/eur/products/ts-wx400da/specifications
MTX RTU8P - http://www.mtxaudio.eu/products/caraudio/item/rtu8p?category_id=14

I know that the Infinity and the JBL are basically the same, and that the Infinity is cheaper, but I can get the JBL locally for 190€, so that's probably what I'm going to end up buying.

If I've missed some details please let me know, I'll provide them.

Stay good

I would really like to know how those things work (that is, IF they actually work). The enclosure size seems way too small for an 8" subwoofer.

I had one, it didn't

I've seen a Clarion on a Land Rover Defender, and I think it's an 8", but of course it wasn't that booming bass.

But for being under a seat, I think some of those do a great job.

I don't have space for anything else, just something that fits under the seat, at max I would accept the sub under one seat, and an external amplifier on the other.

That doesn't surprise me. I was wondering if they are more of the "bass-shaker" kind of solution, and the "8-inch driver" in it actually isn't a driver at all, at least not like normal 8" subwoofer drivers.

It's probably just a "big" woofer that they call a subwoofer

Ok, found an interesting thread: Car underseat subwoofer
And I think it probably is the best option...
