Custom Subwoofer Enclosure and Amp Installed

[m5james]

Hit the damn back button halfway through, so i'm re-writing ALL of this again. Anyways....

So I spoke w/ Michelle, and it appears I need to be a Premier member in order to post on the For Sale forums since they've had issues in the past w/ fraudulant users/spammers posting in there. I'm selling this stuff for cost, and the membership is half the price of the stuff itself, so Mods, please don't delete this post.

I'll basically tell the story of how this all came about to what got me here, and where I am now. When I first looked in the back of the X, I noticed initially that the left side compartment (I have no navi, etc) was larger than the right side. My friend and I measured each area and concluded that we could make a simple square enclosure for the left side that would be slightly larger than the left side. I thought we were so cool figuring this out. The 1st box he made, he made exactly backwards, so now i've got two boxes, one for the left and a matching one for the right. I'd like to sell both if possible, so PM me if you'd like to see pics of these boxes. Once they're painted and I see the mods haven't deleted my post, i'll photobucket the photos and attach them to this post.

Well as he was making the (correct ) left side box, I was browsing around here and Google to try and find out how to wire this thing. I came across the BSW videos and noticed the actual size of the enclosure....dee dee dee on my part! Now, as noted above, we measured and calculated everyones boxes, and Zerochief's came out to be the closest in size to the stock, BSW or JL boxes. Like I said, my installer made me a quick box to test his idea that basically w/ the boxes all being this small, I wouldn't notice the difference between my two .3 cu/ft boxes and the .41 box that Zerochief has made. He was right, but at this point, if I go w/ Zero's design, I can upgrade to a 10" and get all that much more bass from my amp setup.

The dual voice coil 8" that I posted links for above can handle 175watts RMS, but my monoblock amp can easily put out 300watts RMS. Now I know that even going to a 10" w/ a larger enclosure isn't going to get me to what I have in the 7, but it'll be closer. So i'd like to see if anyone is interested in purchasing either box, sub, or both. I paid about $35 per box, so is anyone interested in having a sub and box for say, $50 shipped?

Just let me know if you have navi or anything in the left side compartment before hand so I can make sure to ship the correct box based on whichever side you're going to install the enclosure. As for the amp, i'd honestly buy the same one from the link I posted above. It's a great little amp, monoblock is best if you wanna run a dual voicecoil speaker, and it rocks for being only around $80 w/ that much power. If you need help installing, wiring, etc, I'm always willing to help. I'm a newbie here, but i've been all over Bimmerforums, Bimmfest, DTMPower, 5Driver, Roadfly, etc etc for years, so I like helping and using the forums for what they're designed for imho...to help others save money and DIY'selfers.

So, i've got a left and right side fitted box, $35 plus shipping for each if sold individually. Then all you'd need is a $16 wiring kit from WalMart and the $80 amp listed above, or something else if you don't like that one.

EDIT : We've also already made a trim ring that can be covered in carpet and mounted on the face of either left or right side panel should you decide that you wanna cut the face of the panel open. Please let me know if you plan on doing this or not though, otherwise i'll sell it w/ the other enclosure. Also, to whoever buys just the blank enclosure, I'll throw in a free 8" DVC sub that my buddy yanked from his old home theater enclosure. He gave it to me as a tested until my RE sub came in the mail. It's not nearly as good as the RE sub, but for someone who has absolutely NO BASS right now, everything is an improvement...and free is affordable

These pics are w/ the boxes unfinished. I'm going to paint them tomorrow w/ a rubberized coating so it won't rattle while sitting inside either compartment. I'll redo these pics, but I wanted to put these up in the meantime. Sorry for the size btw, I use Avant Browser and it lets me enlarge or reduce any pics on websites like this one.

Hey Zero, what did you do about the gas door lock mechanism that is behind the right side panel? Honestly i doubt i'd ever need it, so I wonder if you could increase the airspace even more by just deleting that whole mechanism and bending that bracket back and forth till the spot welds break off. That little area is like 2" deep, 6" long and 4" high.

Also, can you still send those high res pics to [email protected]. Thanks.

Looks really good!

[m5james]

Thanks, it'll look better this evening. Surprisingly, still no bites though. Trust me, this little guy sounds good, so for the price, i'd have thought they'd be snapped up sooner. Maybe after the newer and cleaner looking pics...

[m5james]

So one box is coated and ready to go. The other one I will also do if the buyer wants it coated the same way. It's just a simple rattle can type of rubberrized coating.

Ironically, the no name sub sounds good also I imagine it can't handle nearly as much power as the RE sub, but for $35 plus shipping, it's a hell of a start. The other one is still $85 plus shipping. They've both been filled w/ about 4-5 ounces of polyfill to help the sub "feel" like it's in a larger enclosure. These pics were taken moments ago.

[m5james]

So 20 minutes and $10 later, i've coated both inner compartments w/ spray on sound deadener. I coated the left side for using either sub I have now till it/they sell, then the right side for the Zero box that i'll be making once the smaller boxes sell.

james,

you are doing it the right way
but how comes you do not have "anything" in the left compartment?!

[m5james]

Thanks Essam. All i've got over there is the amp, which is tucked down parallel to the sparetire. I did have to slightly trim a bracket that is part of the bracket the holds the amp so I could slide the sub inside the opening, but it took 10 seconds w/ my Dremel. If you look at the pics of the sub enclosure installed, you can see where the fresh metal cut it between the box and the amp.

My X didn't come w/ navi or a cd changer, so i've got all that room over there. Once I build the larger enclosure for the right side, i'm going to use the left side for loose items so they don't have to be moving around in the cargo area. That's part of my issue when selling either of these boxes is that some people don't have an open cargo area on the left if their X came equipped w/ more features than mine.

So, in my relentless pursuit of perfection, i'm still on the fence as to which would be the subwoofer of choice. I've since returned the RE 8", but since then have been all over the highway as to which would be the best sub to use. I really wish I could hear Zerochief's or a similar setup before I rule out the shallow woofer, but at this point it seems to be the one that people on this thread are happy with.

I just spent an hour of work time reading all the post of the other website... Very educational

So, if you didn't have this credit issue with the company you purchased the 1st sub from which sub would you go with?

Thanks
