Well.... since almost no one is interested anyways i guess it doesnt matter. Haven't heard back from Rapid-x in two days... So everything is probably still available.... Sigh

Also, halving the impedance doesn't double the output. As stated in the previous paragraph, the amplifier probably won't be able to handle the additional current meaning that there will most likely severe losses as the internal resistance increases due to heat, the distortion will rise as the load drops, and it will severely shorten the lifespan of the amplifier. What you're suggesting is very likely to destroy the equipment.

In addition, a pair of dual 2 ohm subs can be wired to 0.5 (parallel-parallel), 2 (parallel-series or series-parallel), or 8 ohms (series-series). Wiring them in parallel-parallel would either throw the amplifier immediately into protection mode or damage the amplifier.

Sorry to thread dump, I just don't want anyone to buy the stuff then destroy it and blame the seller.
Did you read what I wrote?

Quote:
FYI a class D amp is best driven at 1 ohm impedence. With both 15 inchers at 2 ohm, wire them both to the amp in Parallel, to drop the impedence to 1 ohm and almost double the amp output (~1400W). Then you'll hear what the amp is capable of, if it can handle a 1 ohm impedence. Not all amps are design for such a beating. I know my Orion HCCAs can.

Good luck with the sale.
Jeez... I wrote "almost double" and "if it can handle". As for the impedence, sorry for the confusion. I forgot they were DVCs (Dual Voice Coils). Your explanation is correct.
