Playing with Big Boy Monster 15"

Looks like a big ball of snakes back there. But hey, as long as it gets the job done, that's all that matters. If those are the amps I think they are, they are incredibly small. You can barely see them.

We want to build a rack for the amps - until then neatening the wires will be a waste

I'm not sure what amps you are thinking of, these are prototypes that we may produce after further testing. So far they have not been an ounce of trouble.

I was kinda thinking they might possibly be the prototypes THE are in your signature

[sundownz 197]

Ah yes - that they are

[loudcav 1]

can I test one out?

[stealth 113]

i have a request. test the spl coil on 220 volts. 50 hz. or was it 60

[sundownz 197]

The outlet will be 60 Hz - not quite right for my car

can I test one out?

Well, if you get one, I want the other one.

Flight recorders

50.2 prototypes

Indeed

Not sure exactly what I'd call them if released... but they are good for about 50x2 @ 4 ohms, if not a bit more.

They are running front and rear components in the Jeep.

[loudcav 1]

call them the 25.2

Flight recorders

ya aircrafts got the blackbox.

so jacob was like we need a silverbox

[sundownz 197]

New box ready

Pics and results Monday!

[ford302redneck 15]

Monday, you damn tease.

[sundownz 197]

New box for testing.

About 3 cubes or so actual box volume - much higher tuning.

that port is sexy

when you gonna test it?

how does it sound against the old box?

[sundownz 197]

I'll meter it today most likely - it sounds louder than before, I can tell it is much peakier to the ear.

[sundownz 197]

149.5 dB right off the bat @ 53 Hz.

My alternator is pretty sad so it starting dropping after that.

Had to pull the CD player out of the dash and hold it to register that

[Aaron Clinton 2,372]

Nice. Surprised you went with that style port instead of an aero.

[sundownz 197]

If I can re-organize the vehicle and get fully external aero-ports I'll try them.

Found another reason for it to be dropping off - our spring loaded terminals were loose as heck. We tightened them up and put CA glue on the nuts so it won't happen again. Sub is holding up just fine - no signs of physical or thermal stress. We aren't sure when the terminals got loose - so the score may be higher. We will meter again soon and see what it does after I get the box secured - it is dancing around alot now

wow 149.5 .....geez....that insane

80

[ford302redneck 15]

Now, all you gotta do is finally turn it up.

[sundownz 197]

wow 149.5 .....geez....that insane

80

Box is also only single thickness

I am going to meter it each time I add a layer to each face to see what kind of gains are made - as a sort of reference for myself and others.

I think the top layer will probably end up being three layers - that will give the cooling vents in the motor more room to breathe and better air flow around the magnet structure in general.

The head-unit is holding us back too. I have to roll the volume up and there is only so fast I can get it to full (no pause) so I am draining current as I go. It is not exactly a high end unit either so I imagine the RCA voltage is pretty poor.
