Welcome to the IHoP
How do you like the IXL 12 compared to the Rl-i 8 ? Only asking about the way it sounds, leaving aside the size difference. I'm half tempted to buy an ixl 10.

Welcome to the IHoP
It does look very nice and actually it is quite easy to do, especially if one is veneering over it. Kerf cuts, braces cut to the curve you want on the inside to glue to to match your curve and your rocking out. Similar things have been built by others. Those were actually done with 3/4" mdf strips all glued together and then 1/4" ply kerfed to cover. Another option is multiple layers of bendable ply. I am a little afraid of kerfing mdf as it will be a bit "digitized" in its bending. Either way, I build a center first in a plane jane square box for temporary use/evaluation before investing time/money into making the cabinets. *think I need an excuse to buy a table saw* Once the kerf is solid you can sand it to remove all the 'digitazation' Sounds like fun. NOT! I hate cutting mdf moreso even on the sanding. Well then, I've seen it done with multiple layers of thin mdf. Not that I have something with using mdf, just that I've seen it done that way.

Ahhh, scoreboards for teh sq competition are here I lost big time on imaging and focus because of the out of phase mid. Better luck next time

I knew you would enjoy pics of that. The owner supposedly has 3, one for drifting, one for drag and one grocery getter.

Welcome to the IHoP
Going to pm joo about a couple things about the mids that are wierd after enclosing them. Too tired to formulate some questions

Welcome to the IHoP
And he ranks me way under a car with 3 midbasses / door ( 2 different types) and an spl sub. Reaaaaaaaaaaly ?

Oh dear, mister golden ears teh sq judge from today really didn't know that my tweeters were off until he asked me what tweeters are those playing. What fucktards.

Welcome to the IHoP
bumpy You can't ask serious questions in the IHOP. It's against the rules. nah a serious question would be like, "what is the magnitude of a the E field inside a Gaussian sphere?" Oh shit, not that again. I failed that exam once

Welcome to the IHoP
they're quite a bit better than they were 5-10 years ago or 15, 20, 25, 30 Still not enough Come on now, they did have a few good mistakes in those years.

Welcome to the IHoP
For comps go for it, for other reasons don't. Obviously for comps, just that I don't have the tl here to measure if it helped or not.

1/4 wave box but front and back ??
The chambers of a 6-th order bandbass are tuned differently. You would have to tune the transmission lines differently too or else you get some serios cancellation. Personally, I wouldn't waste the space with transmission lines.

Welcome to the IHoP
To resin the bottom of the box or not to resin the bottom of the box ? When I doubled that up I used screws from the inside, filled them and the sanded and it's not very smooth now compared to 'raw' mdf.... HMMMMMMMMMMMMM....

Voltage drops after power leaves the amplifier
I never said it would be 40V of voltage drop on the first coil, that would only happen in parallel. I'm still not completely understanding what you're saying....however I was planning on playing with my multimeter on my system tomorrow. Thanks for the help If you never said the voltage across the first coil is 40v, then why did you calculate the power on the first coil using the voltage of the power supply ? Also, the way you said it first, the first coil 'sees' 400w and the second 200w, all out of a 400w supply. This is how things should be calculated, not by following the drawing and interpreting one component at a time and ignoring the rest :

Voltage drops after power leaves the amplifier
The diagrams should be drawn differently. Chose a direction in the loop, write down all the equations and things are easier to understand than writing voltages on each corner of the diagram.

Voltage drops after power leaves the amplifier
It is the voltage drop across a load, not after a load that we are interested in. In the first post you assumed that the first resistor has a voltage drop of 40v, exactly the voltage of the battery, which is wrong, as you can see in the picture you posted. 12v battery, 9v across the first resistor, 3v across the second. There is a drop across each component, and the first component it line will not 'see' all the voltage of the battery. Look at the circuit as a whole, not just going from the positive terminal of the battery to the negative and treating components independantly. To make things easier, wire up something and start measuring voltages. Nothing beats the hands-on approach.

Voltage drops after power leaves the amplifier
Whoa, some very wrong information posted here. When wiring in parallel, each branch of the circuit will 'see' the same voltage and the sum of the currents on the branches is equal to the current supplied by the power supply. In your example, you calculated correctly for the parallel wiring. Series wiring, the sum of the voltage drop across each coil is equal to the voltage supplied by the power supply and the current through each coil is going to be the same. In your example the correcte value is 20V and 10A through each coil. There is no 'first in line' when working on these connections and no '0v returning to the battery'. Trying not to sound harsh here but if this is how the auto electrical class is teaching you, then I feel very sorry for that school.

Subwoofer Fasteners
I've only tried threaded inserts in a fiberglass tailgate and they worked perfect. BASSmaster, 'suki' has some nice threaded inserts.
