Correct me if I'm wrong...

I have 4 midrange speakers and 2 tweeters. All 4 speakers are 8 ohms and the 2 tweeters are 8 ohms. If I wire 2 speakers and 1 tweeter together on one side and 2 speakers and one tweeter together on the other side into 2 separate channels, how many ohms is that gonna give me at the amp per channel? Is it 2.67 ohms? Also, should i get a 2 ch amp and put 2 speakers and 1 tweeter per channel or should i get a 4 ch amp thats 2 ohm bridged stable (Soundstream Reference 644s) and bridge both sides? Which would sound better?

Your not gonna wanna run the tweeters off the same channel your running the mids. Mids generally play 100-3khz (just giving a general example). Where as tweeters shouldn't be playing below 2khz. You send a 200hz note through a tweeter at high volume and..well.. you won't have a tweeter for long.

so if i do it like this my tweets will blow? How should I run this then?

They sell in-line bass blockers that will basically filter out lower frequencies. I've never used them so I'm not sure how well they work, but all they are electrical components that you put in the wire to the tweeter.

Theres one there. It's like a passive crossover in a way, but not the same.

What I would do is Bi-amp, or use a 4 channel amp. Also are you running any type of crossover? Be it from an active HeadUnit, or an external processor?

EDIT : And yes, if you do what you just said your tweeters will blow, likely when the first bass note hits. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

One bass-blocker in series for each speaker. Midrange blocker for the mids and high-pass ones for the tweets. .. 8/3 for 2.6 ohms doesn't really apply here. You're blocking out a lot of the music, so figure your amp for about 5ohms on that setup.

... and of course it would be better to get a component set or the proper configuration and not try to mix stuff like that. BTW, bassblockers are usually just simple capacitors and you can get a cheaper deal if you research them right.

This may or may not help but I had done this same thing with the 2 mids and a tweeter on each channel of a 2 channel amp on high pass and it sounded good. I had put 2 door pods together, each with 2 pyle 8 ohm mids and a pyramid bullet tweeter that was rated at 4-8 ohms which confused me at first. What I did, this may be different for your particular speakers, was I wired them all in parallel, the mids totaling 4 ohms and then add in the tweeter. I soldered a capacitor, size recommended by the mf of course, in-line on the positive lead to the tweeter after the 2 mids so it only effected the tweeter and set the high pass filter on the amps crossover to about 400 hz to keep the bass from the mids. They sounded good and got very loud while staying clean and non-distorted for some cheap speakers.

"size recommended by the mf of course"

Yeah.. that's the key to all basic capacitor high-pass (HP) filters.. figuring out the mf (microfarads) needed. There are charts everywhere if you search for them.

ok so i decided to do the following, please tell me if this can work as well... my focus is to get the max out of my amps and speakers and while staying at a stable impedance. I am going to wire my 4 mids to a single amp. Then im going to run my 2 6x9's into 2 channels of a 4 ch amp, and the 2 tweets into the other 2 channels of that same 4 ch amp. So i will have all the mids running off one amp alone. And then 2 channels for the 6x9 3 ways and the other 2 channels of that very same amp for the tweeters. Since the tweets will be isolated, i shouldnt have to worry about anything anymore, right? I'm also going to get an external crossover (should i get clarion or kicker?), Please let me know.
