They're not great, the volumetric size of the box the sub is in makes a huge difference to the sound it will make, too small it will sound cak, to big and it'll sound cak, the slim setup buts form over function to offer a small package but as your mrs will tell you a small package will get you nowhere laugh.gif

They simply don't have enough air behind them to do there job properly sad.gif

So much for reading everything you wrote - sorry, lol! I managed to interpret it as though you wanted to make a custom shelf and fit an amp + 6x9s!

Though it would be a rather extensive job, I'd go for modifying the standard holes. It's not hard to do, just a few days work and once everything's in place it's all worthwhile!

Yup. Fibreglass helps create wonders, though turning the doors into sub enclosures is not recommended - trust me on that one! But making a pair of 8" or 6x9s fit is possible and since you don't want a boot sub nor fit a custom shelf, I think you're out of easy-to-do neat looking options. Unless you're willing to punch a big hole in the rear seat's back rest to fit a free-air sub... wink.gif

Dependant on pennies:

MDF Stealth Shelf, some nice 6x9's / coaxials / compoments, and an 8" sub all powered by a 4 channel amp. 2 channels to power the speakers and the other 2 bridged to power the sub.

Would make for quite a nice design. If you design it good enough, you could fasten the amp to the bottom of the shelf and so you wont lose any space and nobody would ever know.

Why the extra rear speakers in the shelf, when there's room for a pair of 6.5" coax in the rear doors? smile.gif

Though 'a little extra bass' is a subective matter, I strongly beleive that a single 8" in the shelf will be a very good upgrade!


I'll be building a fibreglass box over the wheel arch to minimize loss of boot space. Most of the space above the arches aren't of much use anyway and there are plenty very good 10-12" subs that are designed to work perfectly in 10-15L boxes! Even the cheap Hertz Energy series are rather impressive. DynAudio and Peerless as well, though they're in a different price range.

I'd put them on hold for now and focus on getting more bass. Upgrading the rears makes little difference when the fronts are already done.
Also, when fitting a sub you can mess about with the high- and lowpass filters, thus letting the sub handle the deeper notes which in turn lets the mid-woofers play with much better control. The sound stage changes drastically once all speakers play what they can actually handle!

I found myself playing much louder in my Seicento once everything was set up properly. Not because it could, but because everything sounded much better with no distortion. Keep that in mind, lol!

What is the width of you parcel shelf? I'm considering going this route as well, though with my Hertz ML2500... Thinking my own advice through it struck me that making a sandwhich-structure with carbon mat, a few aluminium rods, some bitumen strips and these cheap, thin foam 'camping mattresses' ought to be both light and rigid enough if built right. Carbon fibre's not that expensive and doesn't need to look perfect in a stealth shelf! I'll need to strengthen the mounts on my 145 as one's got a will of its own... Definetely an Alfa, lol!

i know nothing about subs atm laugh.gif

erm ive no idea what the width of the shelf is atm....

im going to cut out a hole for the sub, make an mdf template and attach it to the shelf then cover the shelf in acoustic carpet

hopefully that will do the job

Keeping it simple always works. No idea why I've never gone down that route TBH...

HighPass Filter/HPF = how low frequencies your mids and tweeters are limited to.

LowPass/LPF = how high frequencies the sub's limited to.

The fronts may be able to play e.g. 50hz but will likely distort at relatively low volume. Keeping the above 80hz will then increase max volume before the sound breaks up. The same goes for the sub but the other way around. Finding the sweet-spot between fronts and sub allows louder music and better sound. There's more to it than this, but going deeper into this subject is extensive to the point of religion...


Oh, and I meant depth and width of the shelf. Was thinking of the possibility of making the shelf into a box. Even a quite flat design will have a fair amount of volume... But that's just me going nuts and over-thinking/-desisgning everything. Please forgive, lol... I just live this stuff!
