Convertible Box? No way! Lets chat.

Definitely need to cut out the triangles. The bass is mostly just loud, but it is most certainly in the cabin. I have 240 watts on it now, will be 600 tomorrow, the 240 is nearly adequate.

Test drive tomorrow! Final pics tomorrow! Ready to take payments, first 4 get them for $225 for box and porting kit...this is solid, loud, rattle-free bass.

I am interested let me know when they are ready please.

It is 1:00 AM. I just heard the (nearly) final version.

HOLY CRAP, THIS THING ROCKS!

Guys, this is easily the most amazing bass I have ever heard in a car with no roof. Installation is tough, but not impossible. You MUST cut out the rear wall, you MUST install the port tubes properly...did I mention this thing is incredible?

OK, a couple more pictures for detail.

Cutting out the holes for the ports:



Holes cut:




Cutting the holes in the back wall:



An airsaw will do this job, but I went through 9 blades.



Box in place, amps mounted (amp rack is next, but not today):



We also put the sub level controller in the center console:



I think the 4 I have nearly finished will not be enough...when you hear this, prepare to be amazed. Let me know what amp you want on bass, you can change the configuration to give you 1 ohm, 2 ohms or 4 ohms, depending on woofer and wiring choices.

That looks friggin awesome!

The pics are great !! I would imagine if anything is loose in the back seat it will rattle . I would suggest everyone tighten down all your screws and bolts . The port tubes obviously will need some attention ( sealed in place ).

As always great build Luke , without your help most of us would be riding around with rattling BS trunk sub boxes , This setup is a true audiophile sub setup the way it should be done . :up:

Yeah, currently we are researching a better way to secure and seal the ports. The seat may need to be slightly repositioned, but it really is hard to notice. Not exactly the HUGE boom I was aiming for, but damn, this is great bass. Super clean, nice and detailed with plenty of "depth".

Maybe we will take a closer look at some other drivers. I would really like to see how the RE 8" worked in this application. Most other 8" woofers just could not deal with the 1.35 cu.ft. vented side at all, they all developed HUGE ripples...but dammit, I want better power handling!

[StereoInstaller1]

Final design figured out on the ports.

Of course, I have to fabricate it myself...but it will be secure and solid, with a proper seal.

Kind of a pain in the ass, but if you want top notch sound easily in an E30, buy one with a roof.

Guys, I can ship this week, I have these ready to finish. Get on your paypal and get me a deposit NOW!

Hey guys, lets get on this. These boxes are just about ready to ship.

[DRTSRFR]

I'd love to but I've got a top motor :(

I'd love to but I've got a top motor :(

Same here...and the top motor is not even working. Has anyone found a successful way to conver the power top to manual?

[StereoInstaller1]

Yeah, several have been done. Talk to CorvallisBMW, his is a nearly perfect conversion.

Mark, I WILL find a model, we WILL do a power top version...but that is a LOT of space wasted, plus lots of little crap I can't just shove out of the way.

[DRTSRFR]

No worries Luke. I'm old and patient.;)

Thanks Luke. I just sent a message to CorvallisBMW.
