Howdy, I want to setup and active system with equipments and specifications as below: HU: Alpine 9887 (in 3-way mode) 1) Front: Hertz HSK 165 (Woofer: 100Wrms, Tweeter: 120 Wpeak): 125Wrms with its passive xover 2) Rear: Hertz HSK 130 (Woofer: 90Wrms, Tweeter: 120Wpeak): 100Wrms with its passive xover 3) Amp: Hertz HDP4(D-class 1000w): 4*150Wrms @4ohm (4*250Wrsm @2ohm) 4) Sub: Hertz EBX-200: 250Wrms (500Wpeak) 5) Sub-Amp: Hertz HE1D(900W): 1*200Wrms My question is about bi-amping and the finest SQ-oriented design alternatives! First proper solution is to connect each woofer/tweeter pair in parallel with my HDP4 in each of these ways: 1) Channel 1: Right front+rear tweeters in parallel Channel 2: Left front+rear tweeters in parallel Channel 3: Right front+rear woofers in parallel Channel 4: Left front+rear woofers in parallel OR 2) Channel 1: Right+Left front tweeters in parallel Channel 2: Right+Left rear tweeters in parallel Channel 3: Right+Left front 16.5" woofers in parallel Channel 4: Right+Left rear 13" woofers in parallel But I think I'm wasting power for my tweeters! so I could use those 4 channels to drive 4 woofers! And change my HE1D Mono to HE4.1: HE4(800W): 2*100Wrms @2ohm + 1*200Wrms @4ohm To drive 4 tweeters with 2 channels in parallel and bridge the other 2, to drive my sub! In this third method I guess sub would be under-powered! and also tweeters may not sound as good/nice/aligned to/with my woofers! I like nice, clear, flat, real sound with a normal quality, soft sub sound (no vibrations,...) and I was driving same speakers with a EP5 AMP (which I sold) in passive mode for two years: EP5 (630W): 4*60Wrms @4ohms + 1*160Wrms @4ohm Any suggestions/help/experiences?
