Video Request: 2 18's in a sealed enclosure

Lol, comments like that are the reason my jetta no longer has back seats and looks like this:

It will fit, you just have to make a little room here and there...

I had to be practical in one vehicle, I've earned a play vehicle! At least that's what I told the wife.

I'm a bass head through and through. I have a MK4 jetta with a single 18 I currently. In the works is a new baffle to run a pair of 18's IB while I sort out finances and can finish the final enclosure for the back seat area.

With the proper drivers, infinite baffle will be plenty of output. If you really enjoy the "peak" around 35hz that alot of ported boxes have, then you may feel like you are missing something. But infinite baffle and sealed are virtually the same type of enclosure. Airspace is the big difference. Not many 18's perform super well in less than 2 cubes, and the ones that do are usually rather pricey.

I think I can make about 7cu ft work in the MK5, I have to make a cardboard mock up to see if it will slide in or if it would have to be built in trunk.

Hello, I'm getting back into car audio after a hiatus. I'm looking to do a build in my MK5 Jetta. An idea I'm toying with is 2 18's sealed in the trunk. I should be able to just squeeze in enough space for subs forward. This idea originally started as 2 18" in an IB set up but being a basshead at heart I'm worried the IB set up won't live up to what I want.

I know the simple answer is a set of 12's in 3-4 cu ft between 32-35hz, but I'd like to step outside of the box a little bit. Im just short on room to fit 2 15's and a 8" aero port facing subs forward/port forward, so this is my last ditch effort to make large cone subs work in my application.

Hoping to see some videos of 2 18"s sealed or 2 15"s sealed. Suv, truck, hatch, trunk, I'd like to see them all! Thanks in advance.

I built two subs using this Peerless subwoofer, home theater job. Dual 15's in each of the two 5.5 cubic foot, ported enclosures, I want to say three 6” diameter ports by 5’ long due to potential vent velocity issues, f3 around 21Hz?. Powered them with a PAIR of 2000 watt crown amps, simply took your breath away, really impressive.. I'm still toying with the idea of running 2 of them in a 4ft sealed box. Now 3 of them in a 6 cubic ft sealed box (1.3 ohm load) wow! Never done an IB setup. Would think that pre drivers would be suited for that, could be wrong. I think they're around $4-$450 each, not supoer expensive for what they are.

Lol, the jetta is too small to haul the family on vacations so I bought a sorrento. No reason to keep the jetta practical anymore.

Depending on the driver and how much power you have available 7 cubes could work fine. My enclosure will be about 14 cubes after displacements, but my subs are really weird and I'm going for a very low-end oriented substage.

Is that why rap is the genre you hear the most when at a show listening to SPL orientated builds?

TBH I'm having trouble following your responses.

You really have no clue what you are talking about do you? Nobody cares how their system sounds "from the outside" btw.
