Sub wiring help for Infinity kappa One amp

[teejay76]

I'm confused on how to wire 2 10" JBL dual 4 ohm VC subs to the Infinity Kappa One amp. Does anybody have any experience with this amp being that I'm new to car audio? Currently the subs are connected series/parallel 4 ohm into 1 of the positive and negative outputs (what about the other 2 outputs). Do I have anyother better wiring options since the specs say that this:

500W RMS x 1, at 4 ohms 1% THD + N*

800W RMS x 1, at 2 ohms 1% THD + N*

1 Ohm, stableTHD + N: 0.05%Signal-to-noise ratio:

Any help would be greatly appreciated.

Thanks

not sure what kind of power those subs will handle but, since the amp says it is 1 ohm stable, you can wire them parallel/parallel. which will give you a 1 ohm load before rise.

I'm with ^^^ for the most power get down to one ohm, then read your book that came with it and see if you need to bridge those outputs. normally you wouldn't they all flow into the same circuit board because its a mono class d but just in case, if your going more for quality though, keeping it at 4 ohms has alot less distortion

the difference in the thd when running that amp at 1ohm instead of 4 is most likely
99% of people will never hear the difference.

is it really that low?

 

[teejay76]

I was hoping I could wire the subs parallel/parallel. The subs are each rated @ 400W RMS/1200W Peak.

The manual doesn't refer to any bridging of the outputs so I'm assuming you can't. I think I'll wire to 1 ohm stable. Thanks!

So as far as wiring the subs parallel/parallel 1 ohm stable, I just connect the leads to 1 set of the positive/negative outputs on the amps?

Again I really appreciate your guys time and help

Both sets of output terminals on the amp are combined internally. There's just two sets for ease of use. You could connect the subs to each other in parallel then just connect one set of leads to the amp. Or you could connect each sub in parallel then run a set of leads from each sub to a set of terminals on the amp. It makes no difference,
