Never used Super Tweeters, need help with crossovers

[BFeezy 10+ year member]

I bought four Crescendo Audio XST2 supertweeters...I've never ran super tweeters before and I want to know what crossovers, or if possible could I run all four of these off one channel on a four channel amp?

You can use them on one channel as long as your final load is whatever is stable on that amp. You could do either. Just depends on how much power you wanna throw at them.

Also, you can build your own crossovers or use a 3 way active headunit. I chose the active headunit and have my Selenium ST350s running on 125wrms @ >2.5khz.

the four channel is a crunch 1004 which is putting out about 80w per channel @ 4 ohms...could i just run two of them in parallel to the amp on one channel to get a four ohm load? im not really sure what to do because ive been reading that you should run them at 4khz

If they are all 4ohms, you can wire them in Series to bring them back to a 4ohm load,they should have caps on them already,being higher grade tweets.You can dothat 1ch, but keep in mind that on 1ch, its all on rt side/left/and or frt/rear also.You will not be able to fade but to low and high, and not to balance but to one side front or rear of which one ch you put all on.You should be able to add 1 tweet to each ch without any issues in stereo mode with a set of speakers if 4ohm and adding the tweet will bring it to 2ohms, and most all amps are 2ohm stereo stable?

thanks. was running a pioneer DEH6900 until the PICO fuse blew...couldnt deal with the whining any longer

Id run a set on the left ch up front,and the rt with a set of 4ohm components, and bring it to a 2ohm load, and throw the other set in the rear/fill on another set of 4ohm components/2ways,run @2ohms and it will be just fine,In my opinion.That way you have control of the seperation/fading/balancing of all those tweets

I heard about several issues with the grounding problems with those units.Ive just taken out my Eclipse cd3000, and replacing it tomorrow with a Clarion CZ300

do you know any 2 way crossovers that will cross the tweets at 3k-4khz?

I thought that CDT had some ..Just thinking off top my head without looking up though

I just saw a set of xovers that Ive been thinking about getting in my saved section on ebay...They are made by Gravity with some nice sized caps in there along with a nice copper coil, and are 2ways, and the tweet xover set @ 3KHZ-20KHZ,and they are like $20 for a set.

are you trying to go active? if not just purchase some passive xovers and put one on each channel with a midbass

will using just any crossover damage them though? thats really what im trying to find out here...im trying to get the most out of these without damaging them
