KISLOC2 line output convertor for subwoofer in Q50/V37

[HYBRID VL]

as we all know the Q50 stereo from factor has no RCA outs so i bought a Kicker output line convertor to use from the factory sub.

but im wondering as the device has L+ L- R+ R- which ones do i use for my subwoofer?

its only going to be 2 wires as im not worrying about doing my stock speakers just my sub.

do i just use the 2 L+ L- or do i use a combo of L+ R- or what?

I would just use one channel, if you use L+ and L-.  I would connect the R+ and R- input wires together, since it seems to have a 12V input, it might have some small preamps in there and you don't want them sitting with open circuit inputs.

All 4 wires from the head unit into the converter. That's both channels, so you do not lose any bass information that might be in one channel and not the other (which decent music should have, but I'm sure the shit that the kids these days are listening to probably doesn't).

Connecting both channels with alleviate the floating input problem highlighted by Greg above.

As to what you should do with the outputs from it - they should also both be connected to 2 input channels of an amp that can sum the two channels and yield a single low passed output to a single channel. There is often a switch on channel amps to achieve that goal.

If you're just listening to modern electronic music, then you can probably ignore the fact that there's two channels and just listen to one of them. If there is missing information it will probably only improve it by not being able to hear it anyway.
