When fitting a sub woooooofer in a car boot, should it point in any particular direction, like backwards or upward etc?

Shouldn't really make a massive difference due to the way low frequency noise travels, although try a few different positions and see if it sounds better in one of them.

As per the previous post it wont matter unless you are meaning whether to have the cone firing into the box or out of the box.

Point it out of the window to alert teenage girls to your presence, single status and your wish to breed.

Come on, a boot mounted huge speaker in an MDF box is not about music, its about being a tool in a Saxo cruising up and down Rhyl seafront. The odd factory system has some kid of sub, occasionally but generally a Sub is total overkill in a normal car, evena decent pair of 6 by 9s is enough to shake our teeth out !

I had two big ones in a previous car. I used to lower my music down in any public place (as to not look like a tool) and higher it up on the motorway. scratchchin

It made my motown sound really good and seemed to speed up long motorway journeys.

To the OP, just put it in different places and it will sound different. Pick the sound you like thumbup

Disagree.

If you've had a proper, well set up system in a car, just some 6x9s isn't good enough any more.

I'm not talking multiple subs taking up the back seats or anything. I'm just talking a nice SQ setup. 6" comps up front with a punchy 8/10" Sub in the boot. Doesn't take up a huge amount of space and if you love your music, it will make all the difference to the listening experience.

Bass is non directional. Anyway should be fine.

Depends on the car.

Normally it's recommended to go for the boot lid - otherwise you get out-of-phase reflected waves from the bootlid. By pointing it at the bootlid, *all* waves are reflected so stay in-phase.

On the other hand, I get more bass with the subs aimed at the back of the seats (well sealed saloon, difficult to get bass into the cabin).

Try each way smile

Also - I doubt PH is the best place for this unfortunately frown

Exactly this. Thanks

Phase coherence is the key thing for sub setup.
I have never put one in a car though!

You might need to move it around a bit until you find a sweet-spot.
Do you have some sort of phase adjustment available?

As a teenager, the comedy oversized subwoofer I fitted to the car was placed facing the rear of the car. Never played it like a dick, used to turn it down in towns and even more so at traffic lights, only really liked it as it drowned out my awful singing on a motorway.

My mum now has it installed in her Corsa(!) and the chaps who fitted it also put it in facing the boot lid.

My M3 has a built-in subwoofer in the rear and it's facing the boot lid too. Most subwoofers (save the Pimp-My-Ride-let's-put-65535-subwoofers-in-your-car lot) seem to face the boot lid too.

I had a Jaguar XJC a few years ago and fitted a 10" sub in the boot, pointing through a hole I cut into the metal panel behind the rear seats.

Now that definitely gave a bass you could feel wherever you sat in the car, especially if you got the middle rear seat smile

Had one when I was younger, in a Fiesta. Had the amp turned right up. Used so much power the headlights would dim slightly in time to the music. hehe I ripped the whole thing out after a week as I realised the error of my ways!

Depends on the system, some do have a simple phase switching ie 0 degree or 180 degree. Other more complex systems have more detailed controls.

For me I have never got the full on bass style of install but I do like a nice sounding hi quality stereo. I normally run a 12 inch sub in most cars I have owned along with some high quality components. The majority of standard car hi fis are rubbish.

I had a sq setup in my old BMW which was about quality of sound. Single 10 inch sub facing the boot.

Contrary to the misinformation in some posts, it matters not one iota which way the box is oriented.
At 80Hz, the wavelength (full wave) is 14ft long, at 20Hz, it's 56ft long!
Reflections aren't even a consideration - the bootlid/floor is too thin it just passes through.
Your rear seats will attenuate the sound a touch, but still won't offer reflections to your sub frequencies.
