[QUOTE="zane, post: 276, member: 540617"] Ok, sounds like where we need to focus is the wiring, and possibly the crossover points. Your explanation made complete sense, less one part--you said the subs are wired in series 3 -3. what exactly do you mean like this? 3 subs to a series, or wired at 3 ohms mono, etc? According to the info that I have The Thunder 8000 subs are 4 ohms each. This would mean that with an 81000D amp on each set(2) subs with series wiring, there would be a final impedence of 8ohms for each set(2) subs. If they were wired in paralel, the final impedence would be 2 ohms per set(2) of subs. The 81000D has optimal output at 2 ohms. Right from the MTX site---> Specifications Power 12.5 VDC Input 2 Ohm Load 1000 w x 1 Low Level 4 Ohm Load 500 w x 1 Crossover(s) Power 14.4 VDC Low Pass 40Hz-200Hz - 2 Ohm Load 1500 w x 1 Variable 4 Ohm Load 850 w x1 RCA Output Low Pass Only Dimensions (with ISO Feet) Other Features Compression Circuitry 17.8" x 9.75" x 2.1" Thunder EQ 45.2cm x 24.8cm x 5.3cm EBC2 Port [URL="http://www.mtx.com/caraudio/products/amplifiers/thunder81000d.cfm"]http://www.mtx.com/caraudio/products/amplifiers/thunder81000d.cfm[/URL] I would suggest re working the wiring so that each set(2) of subs is at 2 ohms. This should fully utilize the complete potential of the amp. Take it easy, -zane [/QUOTE]
