I have a hifonics jupiter 75x4 at 4 125x4 at 2 and 150x4 1, im pretty sure the amp is underatted seems to put at least 100 at 4 ohms, if anyone has ever benched one let me know what it put out. Anyway should this be good to run rainbow profi vandium 6.5s, 4's and the cal 26s. How should i go about powering them, are they bi ampable even though they are 3 way what should i do, and does anyone have an opinion on, i decided not to cheap out and get someting else to go along with the xxx's so let me know

I belive they come with a X-over u hook ur amp up to and it splits the powers for the 3 different speakers, so u really only need 2 channels. So u can bridge channels and power the speakers. Duno what Ohms u would be running at since i dont know the exact specs on the drivers.

The are not Bi-ampable pm 3.5maxspd or 6spdcoupe both are reps.
I run 100 to each 6.5 so 100 x 2 =200
I run 80 to each tweeter so 80 x 2=160
I run 80 to each 4" so 80 x 2 = 160

You will need to add an amp at some point to run the 4"s thats what I did a small 2 channel to run either the tweeters or the 4".

Just the info. Rainbow specs say min pwr for 6.5 is 75w-120w nominal-180 max. I ran 100 and they sounded great they are pretty effecient at 90db.

You can run it with what you have if it is underatted but for ultimate performance you would need a little more power I believe. You can run the entire set with your 4 channel and be fine if its underrated a bit. If you are making an honest 400 watts you should be fine IMHO. But you PM either of those two guys and they can give you no BS answer for sure. The set has total 4 x-overs.

Worst case scenario is you run one of the best 2 way comp sets money can buy and go to a 3 way later on. Thats what I did at first.
