Hey luke. My car is an auto top turned manual. Is that going to be an issue?

[StereoInstaller1]

/cry so its a never?

No Sir, it will happen. Too many of you guys needs the bass.

So Luke,

Is it the tonneau motor and cover that gets in the way?

Yes, that and the brackets, the relays, all that jazz...plus the bulge on the back of the top compartment.

I will find one, hopefully Lyle can swap cars with me for a few, we shall see.

Guys, I spent a bunch of time looking at a power top vert. I have excellent measurements and photographs provided by another member. There is no way they'll fit like I want them to.

2-3 weeks? It's my gf's driver, so if you have something she wouldn't mind driving for a bit I'm sure we can work it out.

How would your girlfriend feel about driving my E30? Gimme a call, we'll talk about it.

luke, if i took measurements w/ pics would you be able to build the power top box w/ that info. or do you have to have the car to test?

Can you add anything to a manual vert that will simulate the presence of an electric mechanism?

In the meantime, here's some pictures of how the manual box looks finished (without the amp rack, of course).

i am no audio expert by any means, but i was wondering why the vert box uses two woofers and the standard e30 box only uses one?

i have a cd43, all the wiring and both harman kardon amps from a 2000 M z3 that i was thinking about installing in my vert. instead of running the little 5" or 6" woofer/box from the z3 system, could i use your vert box with good results? do i really need dual woofers?

The 'vert box functions on an entirely different basis. A true bandpass, like this one, uses 2 chambers tuned to basically the polar opposites of the desired frequency band. In this case, the box you car came with (that evil metal chamber under your top storage) is the lower end of the spectrum, while the box in the trunk, which MUST be sealed against the wall, provides the energy.

Kind of a bizarre thing, but the woofers are basically only a piston. What you actually hear is the ports and that second chamber.

I will shortly be posting some modifications I recommend you do to that chamber to seal it better and reduce some resonances. As I have said before, these things are a bear to install.

The reason the "roofed" boxes only use one driver is that really is all that is required. The single 8" makes some actual thump, the 10 makes solid bass and the 12 makes thunder...and the Beast boxes are coming soon.

I have a general design philosophy of using the least expensive, least weight, highest performing stuff I can find. Basically, it is because I expect fucking stellar performance and I am a cheapass...so I don't want to have to use all the space, I don't want to have to use a big alternator, running giant wire sucks, all that jazz...but I want the stuff I build with MY name on it to kick ass. I mean, something absolutely without equal, the best you can get, period. This is what I have done all my life and I take it (way too) seriously. You guys have given me a chance to build a new business, develop something that might become a solid thing, something I could retire from, something I can pass to my kids, hopefully...all because of the support I have gotten from just this forum. That is why I try so damn hard to get it perfect, better than any local shop could even think about doing, much less for the prices I charge.

We will get the power top thing figured out. Lyle, I might have to bribe you. Maybe I can give you an E30 of mine to drive back home in while your car stays here for 2 or 3 weeks...there is no way in the world for me to put in 50 or 60 hours of thinking and development time away from my shop. Hell, I can't be that far from my tablesaw!

Luke, if you make it down this way you can spend all the time you want with my power topped vert in my garage.
