Getting more power out of my subwoofer?
I have an Infinity Kappa Perfect (with dual voice coils), which is currently operating in 4 Ohms...
Amp in 2 channel mode pushes 200W at 2 Ohms for each channel SO! In order to get the 200W per channel, the load of each coil of the subwoofer has to be 2 Ohms. Adding a 4 Ohm resistor in parallel would make it 2 Ohms, but half the power would be lost in the resister, so it would only be 100W per channel. How can I wire this up so I can get the 200 watts per channel to each voice coil?

can't you bridge the ampo, get 400W at 2ohm on 1 channel, and just wire the sub so it's a 2 ohm sub.

Unbridged: 200W at 2 Ohms we want the sub to operate each voice coil at 2 Ohms, so bridging won't work... Is there anything we can put with 2 1/Ohm Conductance in series so it will knock 2 Ohms off the 4 Ohm rating of each coil? We just want each coil to be able to take 200W at 2 Ohms... |

what amp do you have?
isn't 400w@4ohms = 800w@2ohms? that is if your sub can handle that... as far as making each coil 2 ohm, i don't think that can easily be done. i mean you could add a 4 ohm subwoofer to each coil in parallel to get a 2ohm load. but then you'd have 3 subs  hehe |
