Thanks Zoomer, I am going to check out those links you posted. I am still on the hunt for a more suiting mid, it's proving to be a pretty hard find!

well, Tang Band W4-1798S 4" Neodymium Midrange Driver | Parts-Express.com

that midrange lines up much better on the frequency response chart.

It's power rating is 40 wrms 80 watts peak... so it actually has worse power handling than the other. Which does worry me, cause i am thinking there is going to be about 70wrms going to the speaker.

Dany, can you explain the advantages of the low/mid crossover point you suggested. I can't find a 4ohm passive xover that has those x-points. And the speakers i have selected meet very well at the 2,200 and 5k points. So unless it's a "no no" i think that cheap swiss xover will make my life nice and simple.

Cheers!

Thanks for the heads-up on the mixing and matching... seems like the selections i have made are just that. 3 different brands and some of the cheapest car audio crossovers money can buy. From what i can tell, it's worth a try. If it's a fail... I guess i will have to find another application for them.

Thank you very much for all the help!!
I'm Goin In, pray for me...

i prefer most voices coming from 1 speaker even 500hz would be a bit high but its not to high.. if u could do 200hz and 8000hz would prob be even better but depends on the car and the mid.. thats y going active is an advantage with 3way. u can play with the xover and find what works best... check sonixelectronics.com u can find some cheap ones. u just dial ur desired frequency and u can control ur gain for each speaker to match the output so it doesnt sound harsh.. the clarion 3way rounds up to about 100$ on there. but u will need 2 more channels of power even if its a cheap 20watt rms per channel for the tweets for a few bux lol

but ya if u want to go custom diy will most likely need a custom xover.

That clarion crossover looks like it would be great, and it's cheap. I do also have a old alpine v12 5 channel that's rated at 50 watts to 4 and 150 to one.

But then i would need to add some more stuff to my shopping cart: amp wiring kit, 3 more rca cables and I would think i would need to upgrade my power supply (correct me if I am wrong [i have a stock battery and alternator]).

Is it really worth all the extra money? With the passive i am looking at $40 dollar price tag for the pair. with the active I am looking at close to $400, if I have to up my power supply.

Thanks Dany, let me know what you think. I really want to go the way u r advising me, but i just don't have the money to up grade my battery and or alternator. For the Drivers alone i am looking at $500 price tag.

Wow you know If i did involve my old v12 amp i would be looking at close to 100wrms to each one of my drivers... that would be quite ideal. Please someone get back to me asap,
if I don't need to upgrade my power supply I am doing it!

For the record my STOCK power supply would have a load of about 1000wrms that it would have to deal with.
(6 drivers @ 100wrms & 1 sub @ 400 wrms)

Looks like my alternator is 105 amps. That should be plenty, right? Also my pdx 5 amp is a class-D amp that runs at 90% efficiency ( if that helps).

Cheers!

This is the crossover in mind, right?

Clarion MCD360 - Crossovers - Sonic Electronix

I don't understand how i am supposed to run 6 channels and a sub...
The only way i can see it working is if the crossover is wired between the amp and speakers

Sorry for the sidetrack.


My money on a new processor is going towards a BitOne. If you want to consider used, the Alpine H700 / H701. I like to run a 3way front plus sub and not many do it.

Rod, I like those speaker choices and would go with the Dayton woofer because I'm a cheapass and it's the better value. Zoomer is steering you right regarding a 2 way setup and Solen.ca. Parts Express means duty and brokerage fees while Solen has cheap shipping. There are also some "boutique" Canadian brands that are worth looking at. Mach5 and CSS come to mind. CSS has a nice 4" full range that could be used in the dash from ~600Hz up. Then you could forgo the tweeter and get one later if you decide you need it.

As far as your question about the crossover splitting the power, the answer is yes and no. It splits the frequency spectrum. How much power is delivered to each speaker depends entirely on the music program.

If you have another amp I would say use it and go active! The crossover you linked is not exactly what you want. It does not have a bandpass channel. The midrange section has no low pass filter. Most people who go 3 way get a BitOne or similar. There is a lot of value in the extra DSP features. If you would rather avoid that expense I urge you to consider a two way with something like the Coustic XM2. Nice and simple. If you definitely want a 3 way consider the Coustic XM5e. You probably would not need to upgrade your battery or alternator either, even with the extra amp because it does not draw full power all the time and a decent battery will handle the peaks.

That Clarion won't do a true 3 way active setup. It does 2 way + sub. Your elec will be fine even with both amps, I ran 2400+ rms in my Cavalier on 85amp alt and stock Walmart Battery. I have a 2 way set of Clarion components with passive xover 6.5" woofer and 1.5" tweet that sounded amazing in my car on 230 rms for less than $200. What part of Ont. are you in?

sorry ya that that xover didnt have midrange bandpass

IDX - ARC IDX Digital Crossover
this one does but a bit more pricey

might as well start off with a 2way and xover and save up some more for a later period and get urself a good processor. like said above Audison Bit one. JBL MS-8. Pioneer P9 deck. i think zapco has something too. one of these would set u in the right direction with basicly everything u will ever want
