Wechle soft

Hello Together I have a question which switch should I buy for: Sub(10″ 800Watt-1000Watt, 4ohm,2x35OZ ferrite magnet) and (2x 5watt 8ohm tweeter) and (2x 3watt 4ohm tweeter) the boxes are in my rolla therefore I can’t take a bigger tweeter as the bass takes the place away (it still has too little space but no matter how much it goes) … it’s loud and also sounded relatively good the only one is just the level separates nich clean enough or even not that’s why I want to do this with a soft one that means that there is a cable with approx.1000-1400watt(I think ma not sinus but it’s closer to the description) from the end stage(backed) … so that’s why the soft one and the “8” cables from the tweeters (so together at an anscluss) and the “2” cables from the bass… Soo my question is now! Which artificial(ebay) soft can you recommend me for this because I have jetz far too many heights in the bass and other Peace P.M.
