So this means I get deeps discounts on installs?

They don't know yet. Have a sleep study in a few weeks. It's either central sleep apnea, narcolepsy, or bad thyroid. symptoms indecate central sleep apnea. It's just a trial to take two times a week to keep me from sleeping 14 hrs a day.

You can keep your NO explode, Buzz Saw, and all that shit. That's for pussies. Dr. prescribed Ritalin for narcolepsy. Made the mistake of taking it on an empty stomach. Feel like I ate a half a jug of NO explode.

I personally prefer the poly. dont care for the different shades of carbon.

Never use a coat hanger or any other object that will conduct electricity. Newer vehicles run data bus to door locks, chime ect. grounding out a wire can fry a computer module. A large zip tie made for AC ducks work best. Home depot and lowes have some up to 4 feet and bigger and they run about 75 cents. To ease installation spray the tie and wires being ran with windex. DO NOT USE WD40 or any other oil based lubricant. They are flammable and can catch fire if a wire that is powered is grounded out. Don't ask how I know that last part of info.

got the ole lady a new civic so I got this one as my new DD. Upgrading to a 12 ported. start of the box below. As long as history doesnt repeat itself I might actually finish this install.

yea, Mms is the moving mass with the air load. That's probaly close.

based on the moving mass (which the program calculated) .163mm is corect and might be close. I had my decimal places wrong. The Cms on my Ethos is ~56uM per newton which is .056mm. So .163 being ~3 times as loose would seem about right

They are way wrong. The BL is obvious. The Cms is how much force it takes to move the cone. The Cms show would be a really really stiff subwoofer

I'd relook at the specs. BL of .5? And a Cms of .16mm/N ?

WinISD does a great job comparing apples to apples. But when modeling subwoofers with small signal real world measurements will be different when modeling the vehicle at listening levels due to parameter shifts. WinIDS also does not a. Oh t for transfer function nor does it a count for inductance which when I did testing on the effects of large coils output was actually reduced upwards of 6db at some points above 40 hertz.

The below was is a 12 sample that was klippel tested. The green is large signal (high voltage to make the cone move to xmax) Thiele/Small parameters. The blue is small signal(only one volt) parameters. The same parameters most all manufactures list for their product. You can see by the shift in parameters (listed by each driver) that small signal parameters are not going to work well in the real world due to parameter shifts when the cone starts moving in a normal fashion. And most computer programs can not account for these shifts

The best place to get a copy is on Amazon. The nominal impedance is what is listed by the manufacturer. 1, 2, 4, ect. The actual impedance will vary greatly depending on frequency, excursion, and heat. Modeling a subwoofer with a program like WinISD is a horrible way to figure frequency response as it can not predict parameter shifts that occur with power. Give me a moment and I'll post some parameters of the same sub with small and large signals applied to it.

awesomeness

i like a good rice noodle

!

use as normal. The adjust EQ settings as needed. We do not perceive frequencies in a linear fashion so your curve on paper will more than likely not be perfectly horizontal

you need to RTA the vehicle first before you know what you need to model for

yep

Same shit happens to gen 3 vipers. A low/bad battery will throw a fuse under the hood pucking up the passkey (or what ever they call it) and creates all kind of crazy ass codes to pop up. Car will turn over but not crank.

See above post

I got a XBL motor ill ship to you for flat rate shipping fee. Got a couple coils I can send with it. ~22mm xmax ~500 watts rms.

Mobile so will be in and out.
