Building my own 3 way, please critique!

hope you're not gonna be running the square kicker woofers, judging on the square subwoofers drawn in the picture.

yep, they're what I have, so they're what I'll use until I can swap them out.

I've decided to go with two of the dayton ND105-4 and DC28FS (thanks Bobby!) They look like really good, budget friendly speakers.

As for a passive crossover, about what frequency do I want to cross these over at?

[BobbyG2]

As high as you can go imo, 6k seems like a good point

I may have missed this, but do you already have your mid/high amps? Depending on what you want out of your 8's, have you considered using a 5 channel? Not so much a suggestion, but just another option, maybe. Depending on the amp, it could prevent the need for splitting your rca's.

I would probably run both sets of components off the 4 channel and run the 8's off the 2 channel. Just to keep everything together.

First off, thanks for all of the replies. I knew I'd get good feedback from this forum.

I have a 50x4 as a temporary setup until I can afford a good amp, but a good amp for the 4"s and 1"s are next on my list of things to buy.

I found the ND105-4 here for only $16. I will be ordering two of them this week.

likewise, here are the tweeters for only $17 each.

I will probably wind up going with this crossover from VM Innovations. Their customer service is simply top notch, and these crossovers are around 5khz @ 12db/octave

Questions:

1 - From what I understand, since the mid is 4 ohm and the tweet is 8 ohm, I can expect half as much power will be sent to the tweet. Also, is it true that this will affect my crossover settings as well (crossing over at a frequency lower than 5khz?)

2 - Lastly, the ND105 is rated at 30watts RMS. I understand that this is a full range rating, but since it will not see less than 100hz, (even higher once the 8's are ordered) what kind of power can I realistically deliver. Yes, I have an oscope to make sure the signal is clean.

I would run the mid/tweet off the four channel with a passive crossover and the highpass on the amp set to 500, and the 8's off the 2 channel with the highpass set somewhere between 60-80 (depends on your sub stage and how badass the 8's are) and the lowpass set at 500.

With the different ohm loads, yes your power will be reduced to the tweeter. The Mid will be crossed at 5k but the tweet will be crossed somewhere else. I'd suggest matching ohm loads and sensitivities.

[79Bronco]

All of this electrical law has my head hurting. Can someone point me to a reasonably priced passive crossover that will work with my 8 ohm tweeter and 4 ohm midbass running at about 40-50 watts rms on the mid and 20-25 watts rms on the tweeter? crossed over somewhere around 5khz-6khz @ 12db/octave.

This is not what I thought when I read "3 way".....

rumor has it kicker subs actually make your car quieter than it was without subs

Thanks for the thread dump!
