Hey JMH,
Does the W6V2 have enough air space? The specs is .9 to 1.50 cu. ft for a sealed box. I want to do exactly what you have done. I printed your pictures out to try to get a quote on how much it would cost for it to be done in my X5, I got quoted around $800. If you don't mind, how much did you pay for yours? I had a kicker 12 L7 and competed in a db competition and hit 148.9. But I love JL, I'm going to power the sub with a 500/1.

When I first heard the dsp system in my X it was pretty good but it lacked the low end that I wanted. So I search for something better but didnt want a bigass box in the back. Looked at the infinity and still it wasnt enough power. I tried a 10" bazooka tube that I had but the bass was too boomy maybe because of the hatchback, but it was loud. So I finally found kicker solobarics.
They only require a small box and plenty of power. I bought 2 l5 10" the new chrome looking ones. Built a box for them and still have some space for cargo. Although the box is bigger than both the bazooka or the infinity, the trade off is worth it. The bass is nice and tight. If you sit in the back it have enough power to give you a free massage. I tried to turn it up all the way as loud as I can sitting in the car with the windows rolled up then went outside. With the doors closed I can barely hear anything from the outside. You can feel a little bass but thats it. But with the windows down you can hear it quite loud. I still havent cover the box yet no time lately. By the way anyone know where I can find matching carpet material for the box? Painting is a way to go but its alot more work.

I love solo barics, I have an L7 12". But it gets even better with a ported box. Are you still running on your factory deck?

DSP Sub Replacement?
 

X5.0

You say you added a new sub to your DSP system. How difficult was that? Did you need a bunch of adapters?

Hi,
this is actually a friends car not mine :) . However as I know the folks pretty well who've done the work on his and my car (and many others :) ) I can tell you it would probably take 3-4 days for building and fitting the box. Now if there'd be sufficient interest they could of course build a mold they can use to speed up the build process. The box will provide enough airspace for the JL sub and it actually sounds pretty good. Now if you want to go all the way out you could consider a 12" (like I did) but this will require more extensive custom work ....

It took me about 3 days off and on to hook up the amp and another day to build the box. I worked slowly and test everything because I did not want to mess anything up. I use a line out converter that i had to hook it up to the output on the main processor or brain. It is located under the spare tire. Thanks to a member from another forum for all the info. I dont know if I can post the link so pm me if you need it.

My '03 X5 has the standard stereo. I opted for the Kenwood wOOx, a very small sub/amp product that takes up very little space and includes a remote that gives some control over frequency and volume. However, small drivers (one is passive) and 50 watts don't give you much. My backseat passengers like the "fill" it provides. To be honest, I don't notice it much. Oh well, I think I spent no more than $150 bucks on it and did the install myself. If I had to do it again, I would probably go with a custom box in the factory sub location.

Like you, I was only looking for an improvement in bass response, not anything obnoxious (BTW, I'm black. Where I'm at, it's mostly "other" folks who have the 'boomin' systems' in their accords, scions, and other imports).

thats a nice setup.

did you have to cut the panel?

Actually, I haven't mounted the wOOx in a permanent location yet (part of the reason being that I'm not sure I will keep it for the long term). It lies flat on the floor of the cargo area (maybe that is hindering performance).

My plan is to either mount it upright on the cargo floor using the supplied brackets or hide it behind the right panel door. I think I would prefer the second option, but I've been a bit too busy to measure the area to see if the wOOx would fit (I hope I don't have to relocate the fuse box). If it does, I may have to cut the panel. Maybe I can insert a speaker grill into the panel.

I will post an update if/when I get to it.

custom box mold
 

Jan, I would definitely be interested in a purchasing the custom box for the rear side panel, if enough people are interested. How many people do they require to make it worthwhile? Any idea?
