Hi Everyone,

I'm looking to upgrade the sound of my coop with a subwoofer install. I want to install it the most stealthy as possible, looking for sound quality rather than volume, and without compromising the boot space.

I searched a bit in the forum and I liked the install in one of the boot side pockets, in the opossite side of the fuel tank. Does anyone knows how big is the space here? I need to know the capacity of the box that could be built to choose the right subwoofer and amplifier.

Another option could be to install two smaller subs, one in each side pocket; using two tiny subs like JL Audio 6w3v3 (6.5", 150 RMS each). Anyone tried something similar to this?

Thanks!
J.

I wouldn't bother with 6.5 subs, 10" is the starting point to be honest, you can buy Rockford fosgate flat subs, prime or power series, both in 10" or 12" and are very good for the money, much better then any flat pioneer but JL also do a flat sub but I haven't tested one out yet.

Shame your not in the uk, I could of done a install for you

I would look at installing a custom enclosure be hind the rear three quarter panels and fitting 8" or possibly 10"s here. Unported because I dislike the boom/ undamped sound. If you have the skills a sealed unit made from fibreglass can be made. One benefit of fitting them in the cabin space is you will here a wider range of frequency not just duff duff duff rattle duffduff.

I don't like ported either but on some applications you need to port, it depends, in cabin subs can be too over powering, it all depends on what your looking for, hi-fi or ear bleeding bass head, iv always found a sub in the boot is the way to go, if you have more then one it will be either your a bass head or your car hase a solid back pannel and you need to vent the bass into the cabin, if you still want subs in the cabin then yes 6.5 are going to be the strait fit option, personaly if your going down this route there are some freak sizes out there in 8" speakers you could try first, some have a 250-300 rms, I have fitted monster jbl 12" co-axle speakers into a 2002 lwb transit before and they where werid to look at! But powered by a PG amp and they sounded very good!

Thank you all for your answers.
It's a shame audioguy that I'm not in the UK for you to make me an install.

I don't want to go for subs installed in the cabin as I read a lot that is difficult to get rid of rattles.

So, subs in the boot is the way to go. And Im discaring the two 6.5" subs option.

And how about my first option of a custom box in the side pocket opossite to the fuel tank? How is the sound experiencie of the guys who made an install here? I'm looking for hi-fi instead of ear bleeding bass.

Thanks!

There is a company that make these to order for loads of cars, but I can't remember there name, last one I fitted was on a e46 BMW convertable

It's like these people but uk based

Somebody once did a fantastic install with a custom-made fibreglass housing in the LH side panel in the boot. Covered it in carpet material and it looked very "original" indeed. I seem to recall he worked out all the volumes too, to get a decent sound. Unfortunately it was a very long time ago, might even have been on Form Mk.1, so a search might not find it. Anyone else (the oldies!) remember this?

This one?

Thanks! Thats the post that I first saw and the one that triggered my interest in this kind of "stealth" enclosure. Unfortunately nobody could tell in that moment the capacity of that space so to decide which sub to fit (and before diciding to go for it, I would like to know that to determine if its worth giving this a try). So, if anyone still has that kind of install it would be nice to receive some feedback.

Thanks!

very nice can we some how add this link to the forum

so it doesnt get lost forever, this has given me a few clues and i may look into making a few for sale

mabe that green shed on my drive will have some use after all

Any ballpark prices if you do decide to make these?

I'd be interested to know about that as well.

Why don't you just measure the available space? A simple calculation of height x width x depth will give you the volume there and then simply match that volume with the sub specification. Have you considered a bandpass design? the space lends itself well to the idea.

If you do an Internet search there is loads of information.

It all depends how much the materials cost and doing a prototype that I can take to bits after I know it fits nice n tight, then use the peices as templates and make up as many as I need, it wouldn't be to expensive, but it's time and where to do it

leave it with me

I feel a group buy coming on............

Me too.

I think you'll have a LOT of interest in this if the price is right.

Oooh sounds like a good idea. I could get rid of the active sub I have taking up the boot!

I could not commit to this without knowing the cost, but I sometimes carry a lot of stuff in the boot. If the housing had the facility of being able to slot a bit of plastic over the speaker to protect it I think that would be good. Prob would not require much - just holders on three sides and a rotating latch (a bit like you see on a shed door) on one side.

I imagine other people would see that as useful as well though, even if I don't go through with this.

maplins do woofer covers
