I searched but haven't found much info on how the power is distributed on a DVC sub. So if there are 2 coils and sub's power rating is 300w RMS for example. There are 3 ways to hook it up, series, paralell and 2 channel. I undestand the first two but what about the 2 channel setup? is it 150w per coil or is it 300w per coil ? how does it work exactly?

and also I heard people saying that the older version Alpine Type R's pound better than the newer ones. I bought the SWR-1021D and it's rated at 300w RMS 1000w peak, where the newer ones are 500w RMS and 1500w peak.

Is mine considered the older version then?

Yeah, that would mean you've got the old type R's, and as for the two channel question, you can wire each coil independently to different channels on the amp, if you dont want to bridge it. If you were to opt for this route though, make sure both channels are putting out the same signal....

As for the power distribution, I believe the power from the amp would be split in half upon reaching the subwoofer. If you're sending the sub 300RMS as recommended, each coil would be faced with 150 watts... correct me if i'm wrong.

My Kicker subs are DVC 2 ohm. I tried it with 1 channel on each coil, 190 wrms@2ohm and then tried the 2 coils in series with the amp bridged 380 wrms@4ohm. Absolutley no difference.
The idea is flexibility, IF i had a different amp, such as a d class that would do 1 ohm, i could put the coils in parallel.

I am now convinced that finding a good Alpine amp cheap to drive this sub is almost impossible. But I think I can get an old school RF 500a2 for about $100 US from a guy on the net. It provides more than enough power... rated at 500w x1 RMS at 4ohm or 250w x2 RMS at 2 ohm, and the birth sheet says it was tested at 646w RMS at 4ohm. I think I can run 2 type R's with that. Thoughts ?
