The pm and first email said you wanted to change but the second email said disregard the first. If you would like to change it let me know on the next payment and I'll recalculate it for you.

Port area is not affected by volume so as long as you are tuning at 32 keep it around 50-75 per sub

right but if the head unit puts out 25 watts a channel I'll need to drop voltage from 10 to 1 volt. A sni-15 would be the easiest way to do it.

I just don't have the time right now to fabricate a source in the dash. I'm not gonna spend the money on a radio when I can get a tablet or one of those tiny Intel computers. I haven't measured output on the headunit but I have enough headroom in power as long as the outputs arent over 6db off I can equalize the bandwith down with the DSP. I'm sure output on the factory unit is under 40 watts so if I use a SNI-15 (10:1) I'll be under 1.25 volts. I'll be using (2) 2x4's. One for tweeter and midrange, one for midbass and bass.

It can, but that isn't the right question. The real question is for what listening levels will doppler distortion and output over run the 4. The goal of a 3 way is to give the FR driver enough support on both ends, but to try to invade on its response as little as possible. Easiest way to have a point source is to use a single driver. Obviously in those mounting locations and with the low frequency noise floor in a car a single 4 on each side isn't enough.This and since the midbass is off axis i don't want it to climb into vocal range too much and throw off staging. As long as is wants and doesn't sound like shit I'll be happy. On another note I really want to keep the factory head unit for the time being. I should be able to use a 10:1 signal reducer from the factory outputs directly into the DSP right?

Alrighty here's what I thing i'm gonna do. The 6.5 in the door W6-1721 sealed in the door .55 cft gives me a F0 at 183 and F3 at 66 hz. Due to the midbass being off axis in the door and its a dedicated midbass I want to keep it under 120 hertz. The 4inch of course is in the kicks on axis. If I seal them I'm looking at a F0 at ~300 and a f3 of ~125. This will give me a null in frequency response between 120 and 300. So I'm gonna port the 4" giving me a f0 at ~125 and a f3 of 86 hz. Any comments?

Because the battery will act as a resistor limiting charging speed

DSP's are WAY outside my skill set as far as designing is concerned. As with my other product I team up with the best in the business. The DSP won't be any different it's just that this supplier will not allow it's clients to divulge who it OEM's for. They are capable of building anything that's needed. It's just that anything ODM and not OEM requires a 1,000 unit MOQ so gotta make sure all the features are right and it's not a pain in the ass to use.

well its in a box. I mean the packaging

Got one here still laying in its box

You said before that you have used a minidsp 2x4? Any features you particularly like and don't like?

The learning curve will be dumb enough for everyone to use. Even my 3 month old daughter can swipe open an iPhone. Dont worry about cost. Just because you think it's expensive doesn't make it expensive to manufacture. I.e. the Ethos.

That is the area as stated by the prompt. You then multiple that by the internal height of the box. Are you using inches or feet and inches

Push all the sides down and make sure the area behind the sub is selected

Right click in the floor of the box. Click selection, area. Multiply the area by the hieght of the box and you got ur volume.

Purely full range amps with only a gain control with the ability to purchase an outboard digital eq. You would simply plug a mic I to the processor and it'll automatically adjust the 31 bands for you. Or you can measure and adjust manually. All via a laptop.

I really have nothing to add to this thread I have some extra workers that needs more hours .... It's ok .. all in fun... don't get butt hurt .. geez I found my edit to be quite funny.

typical power. Start in the middle and work around that.
