 Hi, I have question regarding phoenix gold T1000.2, and eclipse sw8122dvc subs.(aluminum cones) I have 3 of them, and am trying to figure the best way to wire with out blowing fuses, originally I had 60amp fuse for the amp. when I was running 2 subs, but added 3rd with series/parallel wiring and blew fuse in about 30 sec. so any suggestions on either wiring or fusing would be great..

Wanted: More help than most

Let me add that the VC (total of 6) are each set at 3 ohms.  my amp puts out max power at 4 ohms bridged. Do I need a bigger fues? or different wiring set up? again any help is appreciated.

well you can use ohms law to figure out the amps that the system is pulling...

If you take your amps RMS total output power and your voltage and divide you can determine how many amps you are pulling....

if you have 1000rms and 14 volts you would be drawing a little over 71 amps

I believe the recomended size fuse is 80

Good Luck

If we learn from each success and
each failure, then we can improve ourselves

I just want toget this straight. Your running 6 ohm dvc subs at 3 ohms and then how to the amp. If this is the case you might have a problem. I'm not familiar with amp. I s it one ohm stable or  is 2 ohm stereo and 4 ohm bridged. Hold it I justed looked up the amp.

If you have three 6 ohm dvc's run the voice coils in parallel and the all the subs in parallel to the amp. That's a one ohm load and your amp can handle it. I don't know what to tell you about the fuse except that if you ran the subs to the amp in series in would raise your impedance really high and I think that might cause you to blow fuses. I hope I helped. Oh yeah, nice amp.

And if this is wrong let us know how many ohms the voice coils are example; 4ohm dvc operate 2 or 8 ohms, 6 ohm dvc operate 3 or 12 ohms.

Hold up don't do the whole parallel - parallel idea thats posted.  Wire the coils in "Series" Then bridge the amp and wire the subs in parallel.

One more thing, I am not familiar with the amplifier either but I am guessing it is class A/B and by assuming this lets just presume the amplifier is 60% efficient if you are lucky.  Well thing is if it is supposed to supply 1000 watts you'll be drawing about 120 Amps at 13.8V because the rest of that power will be going up in heat.

Actually on the eclipse 12" dvc subs each vc is a 3 ohm load, if I wire each sub in series then each sub caries 6 ohm load,  the amp its self is Phoenix Golds top of the line amp the titanium series, possibly with exception to there limited edition products.the rated handling ability of the amp is 2 ohm stereo, 4 ohm mono. or bridged... any further suggestions? not real sure on class of the amp. but I do know that amps by phoenix gold are among the most efficient on the market..

I would suggest a 80 amp fuse...

wire each sub in parrallel   giving you a 6 ohm load,   wire all three subs in series giving you a 2 ohm load,    bridge at amp 1 ohm     if only 2 ohm stable dont bridge
