My car audio set up is as follows:
Infinity REF5761A 560 Watt 6-Channel Power Amplifier
REF6010CS 6-1/2" two-way compo system (ch 1/2)
REF6012SI 6-1/2" two-way shallow-mount lspeaker (ch3/4)
KAPPA 100.3dvc - 10" Dual-Voice-Coil Subwoofer (bridged ch 5/6) Nom Imp 4 ohms per coil 275 RMS 1100 Peak
Amplifier specs
CEA Rated: Yes
Power Output: 56 watts RMS x 4 channels + 107 watts RMS x 2 channels at 4 ohms and ¡Ü 1% THD + Noise 148 watts x 2 + 287 watts x 1 at 4 ohms, 14.4V supply and ¡Ü 1% THD + N2
Signal-to-Noise Ratio: 82dBA (reference 1 watt at 4 ohms)
Dynamic Power: 117 watts (channels 1,2,3,4); 163 watts (channels 5,6)
Effective Damping Factor: 6.373 at 4 ohms
Frequency Response (-3dB): 10Hz to 57kHz (channels 1,2,3,4) 10Hz to 302Hz (channels 5,6)
Maximum Input Signal: 6.3V
Maximum Sensitivity: 250mV
Output Regulation: .063dB at 4 ohms
Queation is how do i wire the sub since i bridged ch 5/6. I connected the two coils positive-positive/neg-neg. Or would it be better to wire ch 5/6 separately to the two subwoofer coils.

Since this is a 4+4 DVC and you have 2 channels for the sub, your safest option is to run one coil set to each amp channel. (5&6)
You cannot bridge 5&6 channels and run a 2 ohm load here. (both coils in parallel) as the amp may go into protect mode. If you had a 4 ohm SVC, then you can bridge those channels for a bit more output.
However, the few extra watts gained this way, will not have a notable impact on sub performance. Here, the Infinity Kappa Perfect 10.1d (SVC, 4 ohms coil) is a better choice.

Hello Swez,
Just want to know what's the pros and cons of wiring my sub the way it is now (bridged ch 5/6) as to your reply (separate ch 5/6). My goal is to get that booming sound from the sub without putting danger to my amp.
Also, what exactly does a lower OHM number do to your system.
Again, thanks.
Ronald
